The problems of queueing have been caused by improved harvesting techniques, an increase in grain production and by a reluctance on the part of the State Wheat Beard to vary the hours in the day their depots remain open. The resulting delay has caused farmers to incur costs of delay and double handling.Method of solution:Reducing trucking delays would incur additional costs for the Wheat Beard in the form of overtime to depot staff. Determining the optimum hours of operation was the objective of this thesis. A case study approach was adopted and the Gooondiwindi depot was selected for further study. The arrival and departure of trucks was simulated using queueing theory.Recommendations:(a) Opening times should vary according to the harvest.(b) continuous operation throughout tile day, lunch breaks should be discontinued.

The methodology used in this study is the CVRP Multi Trip with Heterogeneous fleet vehicle and the Gravity Location Model based on the heuristic method. Saving heuristic method and nearest neighbor are heuristic methods used in computational studies to determine the order of visits to the formed sub-routes. There are 4 scenarios that are modeled to further analyze the results of these computations, namely: (1) CVRP multi-trip of old location with wings box truck, (2) CVRP multi-trip of old location with Fuso truck, (3) CVRP multi-trip of the new location with wings box truck, and (4) CVRP multi-trip of the new location with fuso truck. The results of the study concluded that there is a relationship between: (1) changes in fleet vehicle type with total traveling distance, (2) changes in depot location with total traveling distance, (3) fuel consumption rate on vehicle operating costs, (4) average vehicle speed on the time back to the depot.

Thus, the optimization of simultaneous unloading/loading operations constitutes an important issue for the distribution center owner/administrator. This paper presents a model based on genetic algorithms optimization techniques for solving the problem of unloading/loading ramps allocation.

Maila" ], "first_author": "Mphekgo P. Maila", "venue": "UpSpace Institutional Repository (University of Pretoria)", "publisher": "University of Pretoria", "abstract": "The contamination of environmental media by total petroleum hydrocarbons (TPH) is a concern in many parts of the world; particularly as most petroleum components like polycyclic aromatic hydrocarbons (PAHs) are either toxic or carcinogens. In South Africa, the sale of major petroleum products by the South African Petroleum Industry Association (SAPIA) reveals that about 21 billion litres of petroleum products are sold per year. These products include bitumen, diesel, fuel oil, illum paraffin, jet fuel and petrol. In addition, 19.5 million tonnes of crude oil are brought into South Africa annually to feed the country’s four refineries. The production of oily sludges at refineries, transportation, storage, and handling of petroleum products by end users, results in environmental contamination. The soil environment is particularly vulnerable to hydrocarbon contamination as most of the accidental spillages by trucks, rail locomotives and pipelines have a direct impact on the soil medium. As most of the petroleum compounds are either toxic or carcinogenic, their removal from the soil is necessary. The literature reveals that biological treatment of hydrocarbons is cost effective compared to other treatment options. However, in order to improve the efficiency of biological treatments, there is a need to understand the microbial diversity of TPH stressed environments and how simple biomonitoring ‘instruments’ can be used to evaluate the removal of hydrocarbons from the soil. The message from the literature indicates some potential solutions to the existing problems associated with soil microbial diversity and biotreatment of hydrocarbon contaminated soil, which must be investigated. The main aim of this work was to evaluate the microbial diversity of the different soil environments disturbed by Total Petroleum Hydrocarbons (TPHs) and the potential use of plants and microorganisms in monitoring and removing hydrocarbons from the soil. In addition, the potential of the culture-independent methods in complementing, the culture-dependent methods when evaluating soil microbial diversity were also evaluated. The polyphasic approach was successfully used in evaluating microbial diversity in both hydrocarbon-contaminated and uncontaminated soils. The approach involved the use of community level physiological profiles (CLPP) and polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) to evaluate the effects of hydrocarbons on the soil microbial communities of both the contaminated and non-contaminated soil layers at a diesel contaminated site. Because of the ability of the molecular methods (PCR-DGGE) to complement the CLPP, the polyphasic approach is recommended when evaluating soil microbial diversity and the effect of pollutants on microbial community structure as the approach appears to compensate for the limitations of each of the methods of evaluating microbial diversity. However, further work is needed to improve the recovery of bacteria from the soil, particularly where the interest is to evaluate the availability of the indigenous microbial populations for bioremediation. The substrate utilisation pattern and 16S DNA fragments of the soil microbial communites in different soil layers at a diesel contaminated site were different. The substrate utilisation pattern of the topsoil was different from the substrate utilisation pattern of the soil layers below 1m. In addition, the substrate utilisation pattern of the contaminated and uncontaminated soil layers were different. 16S DNA fragments of the different soil layers were also different. While the metabolic activities of different samples as reflected by CLPP does not necessarily imply the difference in community structure of the samples, PCR-DGGE revealed differences in 16S DNA fragments and this complemented the results of the culture based methods. The results suggest that the use of functional and genetic approaches (in combination) have a better chance of revealing a ‘clearer’ picture of soil microbial diversity. The distribution of hydrocarbon-utilising bacteria and the efficiency of biodegradation of hydrocarbons vary with soil depth. The biodegradation rate of hydrocarbon was highest in the topsoil compared to other soil layers and this was supported by the high number of hydrocarbon-degrading bacteria in the topsoil compared to soil layers at and below 1m. The results suggest that the biological removal of hydrocarbons varies in different soil layers and that microbial diversity as measured by CLPP and PCR-DGGE varies with depth in hydrocarbon-contaminated soil. The information about metabolic activities of different soil layers is important when assessing the footprints of degradation processes during monitored natural attenuation (MNA). However, further studies are required to understand the effect of (not only) other pollutants, but the influence of soil components (pore volume, level of adsorbents and other environmental factors) on the microbial diversity of different soil layers in both ‘shallow’ and deep aquifers. The microbial diversity of different environments contaminated by hydrocarbons has different community level physiological profiles. At diesel depots where similar hydrocarbons are used for maintenance of locomotives, the number of bacteria (both total culturable heterotrophic bacteria and hydrocarbon-degrading bacteria) was proportional to the level of hydrocarbon contamination. However, there was no significant difference in the level of total culturable heterotrophs (TCHs) and the hydrocarbon degrading bacteria. In addition, the biological activities as evaluated by CO2 production were higher in nutrient amended treatments in which high numbers of TCHs were present. Microbial diversity of polluted surfaces needs to be studied further to investigate the concentration or the thickness of the hydrocarbons layer on the rock surfaces that encourages the attachment or colonization of the TCHs and the hy", "keywords": [ "Ecology", "Microbial ecology", "Environmental science", "Petroleum", "Geography", "Biology", "Bacteria" ], "cited_by_count": 4, "is_retracted": false, "is_paratext": false, "open_access_url": "http://hdl.handle.net/2263/27508" }, { "id": "https://openalex.org/W2787931821", "doi": null, "title": "Donald A. \"Don\" Harrington Interview, May 5, 1977", "year": 1977, "publication_date": "1977-01-01", "type": "article", "language": "en", "authors": [ "Donald A.

Untuk menjalankan pelayanan tersebut pemerintah Indonesia memberi wewenang BLH (Badan Lingkungan Hidup), lembaga resmi pemerintah dalam pengelolaan sampah, untuk membuat TPS (Tempat Pembuangan Sampah Sementara) sebagai wadah untuk menampung sampah masyarakat sebelum dibuang ke TPA (Temat Pembuangan Akhir). Namun, dalam pengelolaannya sering terjadi beberapa permasalahan seperti adanya TPS illegal, penjadwalan pengambilan sampah di TPS yang kurang tepat, adanya keinginan masyarakat untuk penutupan TPS, dan lain-lain. Permasalahan pengelolaan TPS dan sampahnya juga terjadi di Kota Yogyakarta. Dari semua komplain mengenai TPS dan sampahnya di Kota Yogyakarta, komplain terbanyak yang diterima adalah mengenai keinginan masyarakat untuk menutup TPS. Namun, BLH Kota Yogyakarta tidak dapat begitu saja menutup TPS yang diinginkan masyarakat karena jika banyak TPS ditutup maka masyakarat akan kehilangan tempat untuk membuang sampah. Sehingga untuk penutupan TPS, diperlukan pertimbangan mengenai aksesabilitas masyarakat ke TPS.\r Berdasar hal tersebut, penelitian ini dibuat untuk dapat membatu BLH mengetahui TPS mana yang dapat ditutup dan digabung ke TPS lain dengan tetap memperhatikan aksesabilitas masyarakat ke TPS yang ada sehingga masyatakat akan tetap mudah menjangkau TPS dan membantu untuk mengurangi total biaya pengangkutan sampah dari sumber sampah hingga ke TPA. Penelitian ini menggunakan metode mixed integer linear programming untuk penyelesaiannya dan menggunakan CPlex untuk membantu perhitungan.

Hasil dari penutupan TPS tersebut dapat mengurangi total biaya perpindahan sampah dari sumber sampah ke TPS kemudian ke TPA sebesar Rp.m3403.170,00 per hari dari biaya awal sebesar Rp.m3403.170,00per hari menjadi Rp.m37.215.073,00 per hari. Hasil dari penutupan TPS juga mempengaruhi utilitas TPS yang awalnya 91,09% naik menjadi 96,24%.\r \n\nWaste management is a one of government services to the public as a form of business to take care of the environment and public health. For doing it, Indonesian government authorizes BLH (Badan Lingkungan Hidup), the departement of managing waste, to make TPS (Tempat Sampah Sementara or Temporary Garbage Disposal Place) as a place to keep the waste before being disposed to TPA (Tempat Sampah Sementara or Final Garbage Disposal Place). However, BLH always find some management problem such as some illegal TPS, TPS scheduling of garbage collection by the truck, the desire of the public for eliminating some TPS, and others.\r \tTPS and its waste management problems also occurred in Yogyakarta City. Among all of the complaints about the TPS and garbage in Yogyakarta, the most complaints are about people's desire to close TPS. However, BLH can not simply close the TPS just because the public wants it to, because if many TPS were closed so many people will lose a place to dispose waste. So that for the closing of the TPS, it requires consideration for public to go to TPS. Based on this, the present study is made to help BLH to know which TPS that can be closed and merged into another TPS while maintaining public accessibility to TPS so that the public can still easily reach TPS and helps to reduce the total cost of transporting waste from waste sources to TPA. This study uses a mixed integer linear programming method for solving the problem and uses CPLEX to help calculations. The result of optimization of this study is there are 8 out of 110 total TPS can be closed. So that the existing TPS system consists of 14 depo, 18 container and 78 TPSS become 14 depots, 18 container and 70 TPSS after the calculation. The results of TPS closing can reduce the total cost of waste transportation from waste sources to the TPS and then to TPA by Rp.m3403.170,00 per day from the initial cost of Rp.m3403.170,00per day to Rp.m37.215.073, per day and the utility is increased from 91.09% up to 96.24%.", "keywords": [ "Physics", "Humanities" ], "cited_by_count": 1, "is_retracted": false, "is_paratext": false, "open_access_url": "http://etd.repository.ugm.ac.id/index.php?mod=penelitian_detail&sub=PenelitianDetail&act=view&typ=html&buku_id=76076&obyek_id=4" }, { "id": "https://openalex.org/W3184533685", "doi": "10.7910/dvn/uhygaw", "title": "Commercial Vehicle Delivery Activities in Seattle, WA", "year": 2019, "publication_date": "2019-08-22", "type": "dataset", "language": "en", "authors": [ "Anne Goodchild" ], "first_author": "Anne Goodchild", "venue": "Harvard Dataverse", "publisher": "Harvard University", "abstract": "Data was collected over a total of 20 days, covering the period both before and after the locker installation at the Seattle Municipal Tower.

Winter road maintenance is essential for providing safe and efficient service for road users (Usman et al., 2010). It is also costly due to the high cost of equipment, crew, and materials. Optimizing winter road maintenance operations could result in significant cost savings, improved safety and mobility, and reduced environmental and social impacts (Salazar-Aguilar et al., 2012).\\nThe first topic in this study focuses on designing routes for winter maintenance trucks from a single depot. Real-world winter road maintenance constraints, including road segment service cycle time, heterogeneous vehicle capacity, fleet size, and road-vehicle dependency, are taken into consideration. The problem is formulated as a variation of the capacitated arc routing problem (CARP) to minimize total travel distance. A metaheuristic algorithm, memetic algorithm (MA), is developed to find nearly optimal solutions. This is the first study that developed the model that includes all the constraints listed. This is the first study that used the MA to solve the routing problem with all those constraints, and the first study that developed the route split procedure that satisfies all those constraints. In addition, a paralleled metaheuristic algorithm is proposed to enhance the solution quality and computation efficiency.\\nThe second topic of this study focuses on designing routes from multiple depots with intermediate facilities. The service boundaries of depots are redesigned. Each truck must start and end at its home depot, but they can reload at other depots or reload stations (i.e., intermediate facilities). This problem is a variation of the multi-depot CARP with intermediate facilities (MDCARPIF). The second topic includes all constraints employed in the first topic. Since the trucks can be reloaded at any stations, a constraint that restricts the length of work time for truck drivers is also included in this topic. This is the first study that developed the model that includes all the constraints listed. This is the first study that uses the MA to solve the problem and the first study that developed the route split procedure that satisfies all those constraints.\\nThe proposed algorithms are implemented to solve real-world problems. Deadhead (travelling without servicing) speed, service speed, and the spreading rate are estimated by the sample from historical winter road maintenance data.\\nEighteen traffic networks are used as instances for the first topic. The optimized route in the first topic reduced 13.2% of the deadhead distance comparing to the current practice. Comparing to the single core result, the parallel computation improved the solution fitness on 2 of the 18 instances tested, with slightly less time consumed.\\nBased on the optimized result in the first topic, the reduction of the deadhead distance of the second topic is insignificant. This could be due to the network structure and depot location of the current operation. A test instance is created to verify the effectiveness of the proposed algorithm. The result shows 10.4% of deadhead distance can be saved by using the reload and multiple depot scenario instead of the single depot scenario on the test instance.", "keywords": [ "Arc routing", "Routing (electronic design automation)", "Arc (geometry)", "Computer science", "Transport engineering", "Operations research", "Environmental science", "Meteorology", "Geography", "Engineering", "Computer network" ], "cited_by_count": 0, "is_retracted": false, "is_paratext": false, "open_access_url": "https://lib.dr.iastate.edu/cgi/viewcontent.cgi?article=8632&context=etd" }, { "id": "https://openalex.org/W164684565", "doi": "10.1007/978-1-4471-4426-7_6", "title": "An Optimization Method for Designing Ecological and Economical Procurement Logistics System", "year": 2012, "publication_date": "2012-08-09", "type": "book-chapter", "language": "en", "authors": [ "Toshiaki Kurihara", "Kenji Tanaka", "Kazuki Maeda" ], "first_author": "Toshiaki Kurihara", "venue": null, "publisher": null, "abstract": null, "keywords": [ "Procurement", "Business", "Computer science", "Systems engineering", "Operations research", "Engineering", "Marketing" ], "cited_by_count": 0, "is_retracted": false, "is_paratext": false, "open_access_url": "https://doi.org/10.1007/978-1-4471-4426-7_6" }, { "id": "https://openalex.org/W4313008379", "doi": "10.1007/978-3-031-22039-5_12", "title": "Improving the Accuracy of Vehicle Routing Problem Approximation Using the Formula for the Average Distance Between a Point and a Rectangular Area", "year": 2022, "publication_date": "2022-01-01", "type": "conference-paper", "language": "en", "authors": [ "Daisuke Hasegawa", "Yudai Honma", "Naoshi Shiono", "Soma Toki" ], "first_author": "Daisuke Hasegawa", "venue": "Communications in computer and information science", "publisher": "Springer Science+Business Media", "abstract": null, "keywords": [ "Point (geometry)", "Vehicle routing problem", "Mathematics", "Routing (electronic design automation)", "Computer science", "Mathematical optimization", "Algorithm", "Geometry", "Computer network" ], "cited_by_count": 0, "is_retracted": false, "is_paratext": false, "open_access_url": "https://doi.org/10.1007/978-3-031-22039-5_12" }, { "id": "https://openalex.org/W629933237", "doi": null, "title": "NORFOLK SOUTHERN'S ROADRAILER SERVICE MAY BECOME KING OF THE HIGHWAY", "year": 1989, "publication_date": "1989-07-01", "type": "article", "language": "en", "authors": [ "Parry Desmond" ], "first_author": "Parry Desmond", "venue": "Commercial carrier journal for professional fleet managers", "publisher": null, "abstract": "Norfolk Southern's door-to-door RoadRailer operation has grown exponentially since 1986, and most of the traffic is being captured from the motor carrier industry's truckload sector.

The bitumen is shipped to seven depots along the swedish coast line, and from the depots special trucks handle the transportation to customers. Recently Nynas has transformed its supply chain and closed down a few depots. At the moment the company is considering a further reduction of the number of depots. In connection to these discussions an analyse of the companys distributionsystem and of possible changes is required. In this thesis an optimization model is developed that simulates Nynas distribution of bitumen from the depots to the customers. The model is used to investigate the required vehicle fleet size for a number of different scenarios, that is with different depots closed down. The question to be answered is, thus, what depots could be closed without any dramatic increase in the required vehicle fleet size? Scenarios where customers are allocated an increased storage capacity are also studied. The distribution model that is developed is an inventory route planning problem. It is solved by column generation. Each column represents a route and is generated by a subproblem with restrictions on permitted working hours for the truck drivers. Integer solutions are generated heuristically. Simulations that have been performed with the model reveals interesting differences concerning how the distribution is handled in different parts of Sweden. In western Sweden the transportation planning works well, but the distribution in the central parts of the country could be planned in a better way. Results from simulations also show that the depots in Norrköping and Västerås could be closed down without increasing the vehicle fleet. Probably, the existing vehicle fleet size will be sufficient even with the Kalmar-depot closed down. Nevertheless, Nynas transportation suppliers will have to purchase new vehicles if the Sandarne-depot is to be closed. Another interesting conclusion that can be drawn from this thesis is that there is a potential for reducing the vehicle fleet size if the storage capacity is increased at a few chosen customers. A considerably small increase in the storage capacity at a few big customers that are located far from the depots will have a great effect.", "keywords": [ "Truck", "Asphalt", "Distribution (mathematics)", "Column (typography)", "Operations research", "Transport engineering", "Supply chain", "Computer science", "Engineering", "Mathematics", "Connection (principal bundle)", "Automotive engineering" ], "cited_by_count": 0, "is_retracted": false, "is_paratext": false, "open_access_url": "http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-2903" }, { "id": "https://openalex.org/W7167971379", "doi": "10.1145/3795095.3805143", "title": "GRASP-RVND Metaheuristic for Traveling Salesman Problem with Drone Launch Station Location", "year": 2026, "publication_date": "2026-07-10", "type": "conference-paper", "language": null, "authors": [ "Tarcísio Barroso Marques", "José Elias Claudio Arroyo" ], "first_author": "Tarcísio Barroso Marques", "venue": "Proceedings of the Genetic and Evolutionary Computation Conference", "publisher": null, "abstract": "This paper addresses the Traveling Salesman Problem with Drone Launch Station Location (TSP-DLSL), in which a set of n customers can be served either by a truck or by drones launched from strategically located stations.

Historically, building larger vessels has been the main pathway for reducing fuel consumption and cost, however while ships in deep-sea trades competes against similar ships and partly other ship types, their major competitor in short sea trades are the trucks. The benefit of trucks is that they transports small batch sizes, i.e. 20 – 25 tons from door to door, and that the frequency can be anything from minutes to days. In contrast typical frequencies for scheduled shipping lines are once a day, or two or three times a week, and while trucks are standardized and built in huge numbers, short sea vessels are less standardized and typically built in short series. The results of this study indicate that significant fuel and cost savings can be achieved by designing and building slender, simplified and standardized short sea ships and that these savings might be of a similar magnitude as the traditional Economies of Scale benefits which are achievable by doubling the vessel size.

The organization needs to solve a vehicle routing problem with time windows [2], where prisoners have to be picked up and delivered while respecting capacity and safety constraints. A daily demand of about 700 prisoner transportations yields a very complex combinatorial problem, solved by three full time planners. A new heuristic approach, developed in cooperation with Conundra, will be demonstrated. The heuristic enables computing a routing solution for the prisoner transportation problem in less than 100 seconds with a potential to a significant cost reduction. 1 The prisoner transportation problem Prisoners have to be transported between different locations in The Netherlands with a heterogeneous fleet of trucks. The prisoners’ criminal records determines security measures during transportation. The fleet is spread over multiple depots. Trucks are divided in compartments and have different levels of security. A truck must be escorted by employees (guards), with specific skills and based at different depots. Each prisoner transport has several constraints. A pickup and delivery location is given with corresponding time windows that should always be respected. The service times determine the time needed to (dis)embark a prisoner from the vehicle. The prisoner has to be transported with one of the allowed truck types and must be supervised by a minimum number of employees with the requested skills. The prisoner allocation in a truck should respect the allowed combinations of specific prisoners in one truck or compartment. Furthermore, a transportation request can consist of two trips. The first trip (visit trip) brings the prisoner from the prison to another location (e.g. court house or a hospital). The second trip returns the prisoner to the base location. The return trip can only start after a given residential time has passed. Both trips can be either strongly coupled, i.e. in such a way that the vehicle has to wait and execute the return trip as well, or loosely coupled, i.e. when the return trip can be executed by an other vehicle. Each route should start and end in the same depot where the truck was originally located and the total execution time of the route is limited. The objective of the prisoner transportation problem is to minimize the total transportation cost.

The brisk movement of products within the cross-docking strategy has made this an uncompromisable approach for transporting staples, groceries, and perishable items. Although the goal is to maintain a stable environment within the cross-dock centres and vehicles, the loading and unloading process often fails to achieve this. Exposure to an unstable environment affects the quality of goods and initiates their deterioration. The inclusion of the pre-emption technique in the unloading or loading process leads to frequent exposure to an unstable environment, thereby accelerating deterioration. This study explores how pre-emption affects the deterioration rate variation risk coefficient of the products when a limited number of interruptions in the unloading process is considered. A non-linear programming model that considers pre-emption is developed for this problem, and the optimization is performed using an interior-point algorithm to minimize the deterioration rate variation risk coefficient.

The channels differ in capacity, batch size, and transportation delay, e.g., truck vs. train delivery.

DC fast charging was modelled using a piecewise power–SoC curve and applied at candidate locations with assumed maximum charging powers of 400 kW at depots/dairies (Class 1) and 150 kW at farms (Class 2). Three representative milk collection routes were analysed. One route was found to be technically feasible within the SoC constraint when high-power charging was applied at the haulier’s yard and at the dairy, complemented by opportunistic charging at selected farm stops within available dwell times. For the other two routes, the SoC dropped below the minimum limit before route completion even when charging was allowed at all candidate stops using the full available dwell time; critical points occurred at a Class-2 farm stop for route type 2 and at a non-electrified rest area before the final stretch for route type 3. It is concluded that electrification potential is strongly route-dependent and that, for more energy-demanding milk routes, feasibility is primarily constrained by charging time availability and achievable charging power rather than by battery capacity alone. Under the optimistic charging assumptions applied in this study—particularly for farm-based charging—full electrification of the most demanding routes would likely require substantial grid reinforcement and/or operational changes such as route redesign, additional vehicles or dedicated intermediate charging hubs.", "keywords": [ "Truck", "Battery (electricity)", "Piecewise", "Dwell time", "Electrification", "Constraint (computer-aided design)", "Track (disk drive)", "Battery capacity" ], "cited_by_count": 0, "is_retracted": false, "is_paratext": false, "open_access_url": "https://stud.epsilon.slu.se/22062/1/wedelsback-h-20260304.pdf" }, { "id": "https://openalex.org/W2777925272", "doi": null, "title": "Use of RFID technology in intermodal transport", "year": 2010, "publication_date": "2010-01-01", "type": "article", "language": "en", "authors": [ "Dario Medić", "Frane Mitrović", "Mirko Bilić" ], "first_author": "Dario Medić", "venue": null, "publisher": null, "abstract": "Intermodal transport is one of the most revolutionary and important phenomena in the 21st century regarding transport.

To mitigate the congestion impact of truck and van traffic, as well as reduce costs and travel times, last-mile delivery should in many cases be shifted toward non-motorized modes (e.g., walkers and bicyclists) and UAVs.

They offer a fundamentally different performance profile than conventional trucks. They have lower operating costs and higher speeds, at the expense of reduced range and capacity. In scenarios where these limitations are manageable, drones can fully replace traditional delivery trucks. However, in most practical applications, these complementary vehicle types should be strategically combined to leverage their respective operational strengths. This thesis mainly proposes exact mathematical optimization methods for routing problems with drones. The first chapter gives an overview of the literature on routing problems with drones, in the field of operations research, with an emphasis on exact optimization methods. We highlight the variety of problems addressed by researchers and the need to increase the size of the instances solved to optimality. The second chapter briefly recalls the concepts of mathematical programming required for understanding branch-cut-and-price algorithms. We also describe the branch-cut-and-price algorithm used in this thesis, including state-of-the-art components and the labeling algorithm used to solve the pricing problems. The third chapter addresses the Two-Echelon Vehicle Routing Problem with Drones. We propose a new set-partitioning model, in which partial routes corresponding to drone movements are enumerated using a dynamic program. We propose an adaptation of the well-known rounded capacity cuts, specifically tailored to address this problem. In addition, we propose a heuristic branch-cut-and-price based on the exact algorithm. Computational experiments show that the exact algorithm significantly increases the size of optimally solved instances. To further evaluate the model, the algorithm is then extended to address the Park-and-Loop Routing Problem. The fourth chapter addresses the Truck-based Drone Delivery Routing Problem with Time Windows. We develop an exact branch-cut-and-price algorithm and a labeling algorithm to solve the pricing subproblem. We compare two alternative pricing models defined on distinct graphs and show that they are non-dominated: the most effective choice depends on instance characteristics. Computational experiments exhibit the efficiency of the proposed approaches. We also propose new challenging instances with increased drone capacity. The fifth chapter studies a variant of the Vehicle Routing Problem with Time Windows, which integrates two operationally relevant features: flexible departure times from the depot and strict limits on route duration. Although more generic, this problem can be assimilated to a drone routing problem in which the route duration limits the drone’s range. We develop an exact branch-cut-and-price algorithm, featuring a bidirectional labeling algorithm as its primary component for solving the complex pricing subproblem.

A durable collaboration requires attention to more aspects. Carriers typically wish to remain competitive, unconstrained by the collaboration, increasing profits by attracting new customers and withholding information about their customers from the other carriers. They may also wish to provide good services, such as making all deliveries consistently at approximately the same time of the day. To facilitate this setting, we introduce a multi‐period collaborative model, the “consistent collaborative vehicle utilization” framework. Carriers engage in collaboration by borrowing trucks from each other. A borrowed truck first departs from the lender's depot to the borrowing carrier's depot and then visits delivery locations based on optimal routing decisions. Customers are served exclusively by their designated carrier and in an assigned time window, selected from a set of options specified by the customers. We formulate an integer programming problem and develop a branch‐and‐price algorithm to solve it.

Due to the ongoing growth of container ship sizes, there are increasingly high peak situations in landside container handling at logistic nodes in the port, e.g. container terminals, empty depots, freight stations. In combination with rising demands to improve the port's ecological footprint this requires the port and its companies to adapt to the situation in order to reduce congestion. To identify important methods, key parameters, past developments and future trends a classification scheme based on an extensive literature survey on waiting times at terminals and drayage operations is conducted and applied to 71 publications. The analyzed methods to reduce congestion in the port range from optimizing the infrastructure to controlling truck arrival times.

A pinnacle ‘cog’ in the mechanism that is container transportation via road in Southern Africa, is City Deep and Kazerne, yet neither area yields any place regarding trucking maintenance. The road conditions of the area are subsequently threadbare and dilapidated with a great lack of coherence, signage, systematic movement and communication.

As a result, To make use of the undeveloped spaces of City Deep would be to ‘infill’ vacancies, assisting in the promotion of the idea of a compact city.

The Marco Polo Project is funded by the European Union. It began in 2003 for the purpose of achieving sustainable and efficient improvement of the EU’s transportation division. The Marco Polo Project II has been in operation since 2007. More ambitious and larger in scale than its predecessor, it also covers Russia, Belarus, Ukraine, and even the Balkan and Mediterranean countries. The Marco Polo Project II includes a budget of 740 million euros to convert the annual 23 billion tons of truck-transported freight to railroad and sea transportation. This conversion is expected to enable the project to achieve its goal of reducing CO2 emissions by 8.4 billion kilograms. Since the unification of the European countries, the amount of transportation by trucks has steadily increased, and is expected to increase by 60％ by 2013, compared with 2006. Meanwhile, traffic jams, air pollution, and increased CO2 emissions continue to grow more serious. Therefore, it is urgent to swiftly shift from road transportation to railroad and sea transportation. However, shifting from truck transportation, which is relatively inexpensive and also convenient due to its door-to-door delivery, to railroad and sea transportation faces many challenges. Some of the railroad transportation infrastructure is decrepit. There have also been delays in the construction of port facilities for sea transportation, including container terminals. Furthermore, it is necessary to improve the existing physical distribution facilities and logistics parks to adjust to the modal shift.

This paper presents a strategic optimisation model formulated as a Mixed-Integer Linear Program (MILP) to support long-term infrastructure planning for electric delivery depots. The model jointly optimises photovoltaic (PV) capacity, stationary battery storage, vehicle batteries, grid connection limits, and bidirectional charging strategies. A case study of a Swiss parcel logistics company serves as the empirical basis, with two depots of different scales analysed to assess how local conditions shape optimal solutions. Real-world data, including vehicle schedules, energy consumption, PV yield, and dynamic electricity tariffs, are used as inputs. Results show that site-specific modelling is essential, as no general conclusions can be drawn across locations.

In applications such as disaster relief efforts and military operations, the objective is often to finish the delivery or the task as soon as possible, not to plan routes with the minimum total distance. Even in commercial package delivery nowadays, companies are investing in new technologies to speed up delivery instead of focusing merely on the min-sum objective. In this dissertation, we compare the min-max and the standard (min-sum) objective functions in a worst-case analysis to show that the optimal solution with respect to one objective function can be very poor with respect to the other. The results motivate the design of algorithms specifically for the min-max objective.

This paper proposes an evolutionary algorithm to solve the VRPDi. In this variation of the VRPDi, multiple pairs of trucks and drones need to be scheduled.

Thus, the system faces two major uncertainties: one related to unpredictable demand variations, and another concerning imperfect input channels. A multi-variable LQ optimal control law is synthesized in a closed form and subjected to detailed analytical and numerical treatment. It is formally shown that despite uncertainties the controller establishes a non-negative and upper-bounded replenishment signal and the stock level does not cross the reference value.

Effectively operating such systems requires designing cost-efficient delivery networks while addressing the challenges of increasing e-commerce demands. In this context, we focus on a two-echelon location routing problem with mobile depots and direct shipment, where decisions involve locating micro-depots, and designing first and second-level routes. Our model also incorporates the flexibility of direct shipments from the main depot to customers. To solve such large-scale problems efficiently, we propose a metaheuristic approach that integrates a set cover problem with an adaptive large neighborhood search (ALNS). Our ALNS approach generates a set of promising routes and micro-depot locations using destroy and repair operators while using a local search for intensification. We then utilize the set cover problem to find better network configurations. Additionally, we present a decomposition-based cluster-first, route-second approach to solve large-scale instances efficiently. We show the efficacy of our algorithm on well-known benchmark datasets and provide managerial insights based on a case study for the city of Munich. Our decomposition approach provides comparable results while reducing computational times by a factor of 15. Our case study results show that allowing direct shipment can reduce total costs by 4.7% and emissions by 11%, while increasing truck utilizations by 42%.

Generally there are five modes of the transportation of goods like Airfreight, Motor Carrier, Ocean Transportation, Railroad and Pipeline. All of the five modes of transportation exist because of certain attributes that provide one or more advantages other than any modes of transportation. The attractiveness of a particular mode depends on the following important attributes: cost, speed, reliability, capability, capacity, and flexibility. Among of the above mode the Road transportation or Motor carrier is important because it provide door-to-door service. The trucking industry provides an important service to the any nation's economy by transporting large quantities of raw materials, works in process, and finished goods over land, typically from manufacturing plants to retail distribution centers. So Road transportation by using of trucking industry is very crucial for the developing country.

While heavy and depot-level maintenance, troubleshooting, and diagnostics can be, at least in part, addressed with the use of off-board test sets, operator maintenance requires the insertion of some level of sensing and wireless communications technologies into the vehicle platforms. This helps to accomplish the dissemination of diagnostics data to the mechanic to allow him or her to perform the desired maintenance functions. While many of these solutions are being explored and even used in the Service branches, many more may be available for transition from technology developed by globally influential companies such as International Truck and Engine Corporation.

These technologies potentially allow for repair activities to commence as soon as the vehicle reaches the depot, rather than having to go through a diagnostics check with off-board test equipment. This study aims to investigate Army maintenance practices and the impacts on maintenance turnaround time of using maintenance technologies developed to service the global marketplace.

The widespread poverty, supply problems, and high prices led to the establishment of the Warsaw Municipal Supply Facilities (Miejskie Zakłady Zaopatrzenia Warszawy/MZZW). The task of the MZZW fleet was to ensure the supply of food and essential goods to the poorest social groups. Thus, the municipality bypassed intermediaries and their high margins. The articles were distributed through a network of municipal stores. The article describes the history of the buildings at 8 Łazienkowska Street, erected over a hundred years ago, now no longer extant. It was one of the first facilities built by the Capital City of Warsaw shortly after regaining independence. The described complex of buildings was designed from scratch, as the first such facility in Warsaw, meant only for trucks and not for horse traction vehicles. The second owner of the described development was the Municipal Tram and Bus Company, which took over the depot along with the rolling stock. The change of ownership was caused by the seemingly unrelated crash of the New York Stock Exchange. Before the war, Warsaw buses were parked there, the fleet of which was growing rapidly. The defensive war in September 1939 and the occupation removed buses from the streets of Warsaw. After the war, the depot – destroyed in 45% during the Warsaw Uprising – was rebuilt, becoming a symbol of the new socialist Poland. Following the example of the cities of Soviet Russia, with the help of their specialists and trolleybuses, the same service was launched in Warsaw. The depot became the first public transport base to be rebuilt after the war. A trolleybus network plan for the city of Lublin was created within its walls. Before the buildings were demolished, it was once again briefly a bus depot, and, in the end, it played a somewhat important role in the construction of the Łazienkowska Route, becoming the construction base No. 5 for the aforementioned investment.", "keywords": [ "Population", "Truck", "Economic history", "Spanish Civil War", "Economy", "Engineering", "Business", "Geography", "History", "Archaeology", "Economics", "Sociology" ], "cited_by_count": 0, "is_retracted": false, "is_paratext": false, "open_access_url": "https://www.ejournals.eu/pliki/art/20692/" }, { "id": "https://openalex.org/W614189150", "doi": null, "title": "The impact of modifying the Jones Act on US coastal shipping.", "year": 2014, "publication_date": "2014-06-01", "type": "article", "language": "en", "authors": [ "Asaf Ashar", "James Amdal" ], "first_author": "Asaf Ashar", "venue": null, "publisher": null, "abstract": "The study assesses exempt coastal shipping defined as exempted from the U.S.-built stipulation of the Jones Act, operating with functional crews and exempted from Harbor Maintenance Tax (HMT).

Oil depots are not the most energy-intensive in the State Reserve system, but reducing electricity consumption is an important factor in reducing the cost of their products. During the past 10-15 years, the world has seen the widespread and successful introduction of frequency-controlled electric drive to solve various technological problems in many sectors of the economy. Installation of frequency converters on the pumping equipment of oil depots gives the chance of smooth regulation of modes of their work. At the same time loading of electric motors of pumps will be optimum, and losses of the electric power are minimum. At oil depots, the main consumer of electricity is pumping equipment. The technological process of operation of these enterprises involves reverse pumping of fuels and lubricants between tanks and rail and tank trucks. The peculiarity of oil depots is the uneven loading of equipment due to different needs in the number of pumped oil products over time, so the loading of the pumping station will also be uneven due to different pressure and supply in the pipelines. To maintain the set mode of operation of the pumping station when changing external factors affecting its operation, it is necessary to monitor and regulate the modes of operation of pumping units. This function can be divided into two areas: regulation of hydraulic modes of operation of pumps, which is used at oil depots, and regulation of energy efficiency of pumping station equipment. The calculation of technical and economic indicators of the introduction of frequency-controlled electric drive is performed on the example of state enterprise \"Aystra\" Chernihiv.

For each service area and wave, a truck departs from a depot and completes a route, including a visit to a microhub and a set of customers. The rest of the customers receive deliveries from crowdshippers, who pick up packages from the microhub. We derive a set of analytical results for this base model of the problem on a solid grid to provide strategic decision‐making insights into when crowdshipping can be implemented in a service area at a cost–benefit compared to truck delivery. For this setting, we derive the minimum cost solution based on whether the grid is even or odd and the location of the microhub. We find that the structure of the solution changes at certain breakpoints in the ratio of the cost of crowdshipping to the cost of truck delivery. To understand how the value of crowdshipping changes across settings, we provide a mixed integer programming formulation and extensions to more general settings that we evaluate in a set of computational experiments. We consider the impact of factors such as limited crowdshipper availability and multiple microhubs in a service area.

This study aims to analyze the container operation management at the terminal, focusing on four key management functions: planning, organizing, implementing, and controlling. The study uses a qualitative descriptive approach, collecting data through interviews, observations, and documentation. Triangulation is applied to ensure the validity of the information. The results indicate that applying these four management functions greatly contributes to smooth terminal operations.

Coordinated execution across the vessel area, yard, and gate supports smooth processes, despite challenges such as truck queues and technical issues with the gate’s CTOS application.

In recent years, however, the introduction of internet-based, online library catalog systems has allowed users to search the library's catalog, select and reserve a book or a video and have it delivered to the branch of their choice. Consequently, the demand for delivery services is increasing at rapid rate in large urban public libraries systems. Having experienced a similar growth in the demand for delivered items, the San Francisco Public Library (SFPL) commissioned a study to improve its delivery operations. Using operations management concepts, such as pre-sorting of material to avoid double handling, cross docking to reduce cycle time of delivery, and workload balancing among delivery routes to effectively increase delivery capacity, the delivery operations were restructured. We developed optimization models for library delivery operations that specifically accounted for pre-sorting, cross docking and route balancing. We also developed heuristics for solving these models and implemented them to redesign the delivery operations at SFPL. The redesigned delivery operations will reduce the cycle time and the cost of delivery by almost half. Furthermore, through balanced utilization of existing truck capacities, the delivery operations will be able to handle significantly larger delivery volume and thereby accommodate future delivery service growth without additional investments.

Therefore, assessing and identifying hydrocarbon-degrading bacteria will contribute to the biodegradation of the toxic compounds. Methods: Pure bacterial cultures were isolated from two different locations, Petrol Depot R57 and Sasol Truck Stop. The soils were excavated from cyclohexane-contaminated areas and then transported to the laboratory for biological analysis. The ability of the bacterial isolates to use cyclohexane as the sole source of carbon was used as a requirement for the identification of the above-mentioned isolates, followed by confirmation of such identity after performing several tests. Results: Bacterial isolates from Sasol Truck Stop and Petrol Depot R57 were assessed for cyclohexane biodegradation. Bacterial growth was observed at 6% cyclohexane for the Sasol sample but not the Petrol sample due to its toxicity. Both locations required biostimulation at lower concentrations. Morphological and Gram staining differentiated the isolates as followed: Petrol samples had varied bacterial types, while Sasol samples had bacteria only constituted of Gram-positive cocci. Biochemical tests identified varied oxidase, catalase, citrate, indole, lactose fermentation, and motility results. DNA analysis showed contamination during extraction, but effective 16S rRNA amplification and sequencing identified Staphylococcus warneri and Bacillus subtilis, indicating promising bioremediation applications.

Due to the large computational effort needed for optimizing TSP tours, researchers have developed approximations that relate the average length of TSP tours to the number of points n visited per tour. The most widely used approximation formula has a square root form: √n multiplied by a coefficient β. Although the existing models can effectively approximate the distance for conventional vehicles with large capacities (e.g., delivery trucks) where n is large, approximations that seek to cover large ranges of n, possibly to infinity, tend to yield poorer results for the small n values. Thus, this dissertation focuses on approximation models for the small n values, which are needed for many practical applications, such as for some recent delivery alternatives (e.g., drones). The proposed models show promise in analyzing the real-world problems in which actual tours serve few customers due to limited vehicle capacity and incorporate realistic constraints, such as the effects of a starting point location, geographical restrictions on movements, demand patterns, and service area shapes. The dissertation may open new research avenues for analyzing the new transportation alternatives and provide guidelines to planners for choosing appropriate models in designing or evaluating transportation problems. Approximation models are estimated from the following experiments: 1) a total of 60 cases are developed by considering various factors, such as point distributions and shapes of service areas. 2) Solution methods for TSP instances are compared and chosen. 3) After the TSPs are optimized for each n, the TSP tour lengths are averaged. 4) Lastly, models for the averaged TSP tour lengths are fitted with ordinary least squares (OLS) regression. After the approximations are developed, some possible extensions are explored. First, adjustment factors are designed to integrate the 60 cases within one equation. With those factors, it can be understood how approximation varies with each classification. Next, the approximations considering stochastic customer presence (i.e., probabilistic TSP) are proposed. Third, the approximated tour lengths are compared with the optimal solutions of vehicle routing problem (VRP) in actual rural and urban delivery networks. Here, some additional factors, such as a circuity factor and service zone shape, are discussed.

A comprehensive review of data is presented, showing that urban freight statistics do exist in many cities but data collections are made in a piecemeal approach and with very different methods, making comparisons difficult. Overall, urban freight has become crucial to modern urban economies, as customized and more frequent deliveries are required by stores, businesses and households. The chapter presents issues such as trucks’ environmental impacts, goods movement’s inefficiencies, and 'logistics sprawl', i.e. the location of warehouses in suburban areas. Strategies and policies are presented, showing the emerging field of 'city logistics', i.e. innovative projects for clean and energy efficient urban deliveries. Local policies from cities around the world are presented and compared, showing the difficulties for many local governments to manage and regulate urban goods movements, whose drivers are global supply chains and changing consumer demands. Some success stories are presented such as London’s Low Emission Zone, Motomachi Urban Consolidation Center, the Clean Truck Program in Los Angeles ports.", "keywords": [ "Truck", "Urban sprawl", "City logistics", "Business", "Supply chain", "Consolidation (business)", "Transport engineering", "Traffic management", "Regional science", "Environmental planning", "Urban planning", "Geography" ], "cited_by_count": 0, "is_retracted": false, "is_paratext": false, "open_access_url": "https://hal.science/hal-00855006" }, { "id": "https://openalex.org/W2911127983", "doi": "10.15735/kls.2018.26.4.008", "title": "A Model for Multiple Traveling Salesman Problem with Mixed Type Vehicles", "year": 2018, "publication_date": "2018-12-01", "type": "article", "language": "en", "authors": [ "Jinwook Kim", "채준재" ], "first_author": "Jinwook Kim", "venue": "한국물류학회지", "publisher": null, "abstract": "As carbon emissions increase, environmental awareness is getting stronger and electric bicycles are being used in the field of logistics.

The aim is to improve the process of designing the routes to follow by a heterogeneous fleet of trucks that transport a large number of vehicles (of different features (volume, cost, etc.), from 8 major origins to more than 3,000 possible destinations spread both across the Iberian peninsula (Spain and Portugal), and some destinations in the rest of Europe (mainly France and Germany). The pursued improvements compared to the current situation, embrace the maximum occupancy of trucks, the total travelled distance, reduction of delivery times, minimization of distance travelled with minimal or no occupation of the truck, etc. Firstly a review of the methodologies currently used for the resolution of this type of problem is presented. Within the VRP problems (Vehicle Routing Problem), our case can be classified as a hybrid between the VRPTW problem (VRP with Time Windows) and the MDVRP (Multi Depot VRP, VRP with multiple locations). After analyzing both the exact and the approximate resolution methods, delving more into the latter given that they better conform to the problem that concerns us, the paper review different types of algorithms: local search, two stages, evolutionary, GRASP, smart colonies and solutions with multi-agent systems. Among them, GRASP algorithm was finally chosen for the problem resolution. Furthermore, a friendly WEB application has been developed to be offered to the operator responsible for the design of the routes. The Web will provide the operator with possible solutions for him to evaluate and validate based on their experience. After a series of tests, the use of this optimization tool reveals to bring improved solutions, particularly as regards the reduction of the delivery times and maximization of the occupation of the trucks. One of the main problems in current operations is the delay in the delivery of some orders, when there is no enough demand to fill a truck. The application resolves this problem by placing vehicles in trucks that are already filled with highly demanded vehicles for a nearby target. The delay in any of these specific vehicles to give out to the isolated ones is a preferred solution. Another problem that the application solves is the minimization of the distance travelled empty, ensuring that the end of the routes, are close to loading points. In short, although the application is still in testing phase, it has offered an important aid to the operator responsible for the routes design.", "keywords": [ "Vehicle routing problem", "Truck", "GRASP", "Computer science", "Routing (electronic design automation)", "Container (type theory)", "Reduction (mathematics)", "Transshipment (information security)", "Operations research", "Minification", "Mathematical optimization", "Process (computing)" ], "cited_by_count": 0, "is_retracted": false, "is_paratext": false, "open_access_url": "http://www.adingor.es/congresos/web/uploads/cio/cio2012/SP_01_Gestion_Logistica_y_Cadena_Suministro_Transporte_y_Distribucion_Fisica//750-757.pdf" }, { "id": "https://openalex.org/W2903700005", "doi": "10.17825/klr.2018.28.5.65", "title": "A Simulation-based Performance Analysis of a Digital Assorting System", "year": 2018, "publication_date": "2018-10-30", "type": "article", "language": "en", "authors": [ "Jeong Man Lee", "Jeong Hwan Kim", "Young Joo Kim", "Soon Do Hong" ], "first_author": "Jeong Man Lee", "venue": "한국물류학회지", "publisher": null, "abstract": "편의점 점포를 거래처로 하는 물류센터에서 작업자는 디지털 어소팅 시스템(Digital Assorting System, DAS)을 통해서 제품을 각거래처로 분류한다.

However, fluctuations in crude oil prices and evolving emissions regulations have prompted interest in alternative powertrains to enhance fleet energy resiliency. This study paired real-world operational data from a large commercial fleet with high-fidelity vehicle models to evaluate the potential for replacing diesel internal combustion engine (ICE) trucks with alternative powertrain architectures. The baseline vehicle for this analysis is a diesel-powered ICE truck. Alternatives include ICE trucks fueled by bio- and renewable diesel, compressed natural gas (CNG) or hydrogen (H2), as well as plug-in hybrid (PHEV), fuel cell electric (FCEV), and battery electric vehicles (BEV). While most alternative powertrains resulted in some payload capacity loss, the overall fleetwide impact was negligible due to underutilized payload capacity for the specific fleet considered in this study. For sleeper cab trucks, CNG-powered trucks achieved the highest replacement potential, covering 85% of the fleet. In contrast, H2 and BEV architectures could replace fewer than 10% and 1% of trucks, respectively. Day cab trucks, with shorter daily routes, showed higher replacement potential: 98% for CNG, 78% for H2, and 34% for BEVs. However, achieving full fleet replacement would still require significant operational changes such as route reassignment and enroute refueling, along with considerable improvements to onboard energy storage capacity. Additionally, the higher total cost of ownership (TCO) for alternative powertrains remains a key challenge. This study also evaluated lifecycle impacts across various fuel sources, both fossil and bio-derived. Bio-derived synthetic diesel fuels emerged as a practical option for diesel displacement without disrupting operations. Conversely, H2 and electrified powertrains provide limited lifecycle impacts under the current energy scenario. This analysis highlights the complexity of replacing diesel ICE trucks with admissible alternatives while balancing fleet resiliency, operational demands, and emissions goals. These results reflect a US-based fleet’s duty cycles, payloads, GVWR allowances, and an assumption of depot-only refueling/recharging. Applicability to other fleets and regions may differ based on differing routing practices or technical features such as battery swapping.", "keywords": [ "Powertrain", "Truck", "Diesel fuel", "Payload (computing)", "Internal combustion engine", "Compressed natural gas", "Renewable energy", "Fossil fuel", "Green vehicle" ], "cited_by_count": 0, "is_retracted": false, "is_paratext": false, "open_access_url": "https://doi.org/10.3390/wevj17020074" }, { "id": "https://openalex.org/W7207530917", "doi": "10.5281/zenodo.22272747", "title": "Air Shower", "year": 2026, "publication_date": "2026-09-03", "type": "other", "language": null, "authors": [ "hospitaldoor" ], "first_author": "hospitaldoor", "venue": "Zenodo (CERN European Organization for Nuclear Research)", "publisher": "European Organization for Nuclear Research", "abstract": "Our pharmaceutical air shower are essential for maintaining cleanroom integrity, removing contaminants from personnel and equipment before entry.

Under the umbrella of the generic term City Logistics, these initiatives try to take advantage of the coordinating power of a municipal government to convince urban delivery companies to participate in collaborative schemes that by reducing truck trips, increasing the utilization of trucks, or both, may reduce the negative externalities associated with urban truck traffic. While most research on this topic focuses on freight models (Holguin-Veras, et al, 2001), freight transport networks (Yamada, et al, 2010) and urban freight project evaluation (Thompson and Hassall, 2005), not much research has been conducted to understand the behaviors of urban carriers and freight receivers in response to the cooperative multicarrier delivery initiatives and assess its impacts on a disaggregate level. Some researchers had studied the behavioral modeling between freight agents (Thompson and Hassall, 2005). It is important to investigate the interactions between freight agent and how those relations impact decision making and policy implementation. To investigate a cooperative multicarrier delivery initiative and assess its impacts on a disaggregate level, this report is divided into two parts. The first part studies freight delivery patterns in New York City and related influential factors.

The problem of assigning loads to vehicles and creating optimal routes is called the Vehicle\r\nRouting Problem (VRP). The standard VRP consists of several customers, which all have a\r\ndemand and a location. Further, there is a fleet of vehicles that has to fulfill the demand of the\r\ncustomers and all vehicles start their routes from the depot.

This statement seems simple and straightforward. However, there is little attention among designers of freight transport systems for the fact that the evolution of logistics services is a key determinant for the requirements placed upon transport systems. Quality requirements for freight transport (in terms of e.g. speed, reliability, flexibility and costs) are derived from economic activities, including logistic activities like packaging, warehousing, cross-docking and handling. As logistics services are being restructured at an unprecedented rate, both geographically and commercially, it is important to take these changes into account. This paper presents an outlook on expected changes in logistics structures, and demonstrates some related innovations in new freight transport systems. The paper is built up as follows. First, an introduction is provided of the nature of changes in logistic services, including the expected impacts on quality requirements in various transport market segments. The results of three studies done in the Netherlands concerning the feasibility of innovative freight transport networks were consolidated. These studies include 1) a national network for underground freight transport, 2) an increase in truck carrying capacity through multi-trailer truck networks and 3) a new inland waterways network using floating stocks to supply retail distribution centers. The logistical characteristics of each system and the results of the feasibility studies (including the critical succes factors of each system) are described. In the final section, the findings are summarised and recommendations provided for further research and development work.

One of the most challenging distribution problems is the last-mile delivery which generally refers to the very last leg of the delivery operation when a parcel is moved from a depot to the end customer. Despite the significant increase in the number of products ordered online and delivered directly to customers, the reliance on truckbased delivery has remained unchanged for decades. The integration of drones in the last-mile delivery can overcome many operational challenges and provide competitive advantages. Traditional optimization algorithms for truck-drone suffer from high computational time and can solve only small-sized problems. This study focuses on finding an effective approach for solving the last-mile delivery problem. We propose a hybrid machine learning model to tackle the problem of delivering products to a set of delivery locations using a modern truck equipped with multiple drones. A constrained clustering algorithm is proposed to cluster delivery locations based on user-specified constraints in the first stage. The center of each constrained cluster serves as a launching site where the truck can park, and drones can be dispatched to make all final deliveries. A deep reinforcement learning model is proposed in the second stage to find an optimal route among all clusters. Extensive experiments are conducted to evaluate the proposed approach.

However, previous works disregarded or assumed the load capacity of drones as fixed values for simplification in truck-drone delivery, such that there is no split delivery assignments on drones. Yet in real-world applications, considering drone endurance and payload capacity, it is highly practical that they deliver in a split way. This paper concerns the novel variant: the split delivery vehicle routing problem with drones (VRPD-S). We deal with the cases where each truck is equipped with a single drone, for serving a set of customers with minimal delivery duration. This problem is challenging since drones can perform multiple deliveries for a single customer node, i.e., the customers' demands are allowed to be split. Whereas trucks follow the vehicle routing problem and meanwhile need to synchronize with drones at the depot or demand points. We model this problem as a mixed-integer linear program and implement a problem-guided predictive search combined with an adaptive large neighborhood search (PS-ALNS) procedure to solve it. Extensive computational experiments were carried out on benchmark instances available in the literature. According to the numerical results, our model is validated and the proposed algorithm works effectively in small and larger instances. Split deliveries can generate savings both in terms of number of vehicles and travel costs, and lead to more flexible and efficient results for the overall delivery system.", "keywords": [ "Drone", "Vehicle routing problem", "Routing (electronic design automation)", "Computer science", "Computer network", "Biology" ], "cited_by_count": 0, "is_retracted": false, "is_paratext": false, "open_access_url": "https://doi.org/10.5281/zenodo.7486901" }, { "id": "https://openalex.org/W2548800952", "doi": null, "title": "Logistics land use - A buffer between harbour areas and urban neighbourhoods?", "year": 2008, "publication_date": "2008-01-01", "type": "article", "language": "en", "authors": [ "Tina Wagner" ], "first_author": "Tina Wagner", "venue": null, "publisher": null, "abstract": "The Port of Hamburg, being the second largest harbour in Europe, is directly adjacent to the urban neighbourhood Wilhelmsburg.

Urban construction sites are often located in close proximity to public streets and roads with a high traffic volume, and a high share of vulnerable road users. Truck appearances generated by a construction site inject temporary risk into the urban areas, as urban roads are not primarily designed for trucks, and the truck drivers might not be familiar with local conditions. This results in safety challenges for the project owner, construction and transport companies, and their drivers. By Norwegian law, project owners and construction companies are obliged to conduct a risk assessment of the site. However, such assessments rarely include traffic safety outside of the site. Therefore, the objective of this research is to gain a better understanding of the safety considerations associated with deliveries to urban construction sites. Particularly interesting is the information flow between stakeholders involved in construction site operations, concerning the site-specific access and loading information truck drivers receive when delivering to construction sites. Based on the findings, recommendations are suggested to improve the flow of necessary information for improved safety while delivering to sites.\\n\\nThe qualitative research approach consists of in-depth and focused interviews. The first set of interviews was conducted with seven truck drivers and six transport company managers. Interviews were audio-recorded and summarized to identify safety problems and barriers in the safety information flow regarding access, on-site driving and loading. Based on the findings from these interviews, a construction site manager and a project owner were interviewed in a second round of interviews. The main purpose of these interviews was to gather their insights on findings identified in the first set of interviews, as well as to gather more data regarding the information flow. \\n\\nThe findings from the first set of interviews indicated that the drivers rarely receive more information than what and where to deliver, and often with little advance notice, making it challenging for the drivers to plan their next deliveries. Yet, most drivers stated that the site s address was sufficient to conduct a safe delivery. Furthermore, most of the interviewed company managers considered the courses required by law and having a driver s license as sufficient for the safety. However, most drivers reported the mandatory courses to have limited value regarding safety, and that the understanding of risk and learning to conduct safe deliveries is primarily gained through the everyday work experience. Despite the interviewees general agreement that the status quo was good enough , areas for improvement were identified. E.g. plans to show where to enter and unload at delivery sites was pointed out by drivers as missing and desired information. Additionally, one transport manager highlighted that providing specific safety-related information regarding particular sites and/or routes is beneficial to drivers. However, providing too much information could make it challenging for the drivers to remember specific information. \\n\\nA general safety management system of construction site truck-traffic, supported by law or regulation is suggested to address the consistency and quality of the safety information flow between project owner, construction site management, transport leaders and truck drivers. While this study is focused on urban construction operations, the results could also be applied to other urban delivery operations.", "keywords": [ "Transport engineering", "Construction engineering", "Engineering", "Civil engineering", "Computer science", "Forensic engineering", "Environmental science" ], "cited_by_count": 0, "is_retracted": false, "is_paratext": false, "open_access_url": "http://hdl.handle.net/11250/2565567" } ]
