Book Synopsis Pro-active Dynamic Vehicle Routing by : Francesco Ferrucci
Download or read book Pro-active Dynamic Vehicle Routing written by Francesco Ferrucci and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with transportation processes denoted as the Real-time Distribution of Perishable Goods (RDOPG). The book presents three contributions that are made to the field of transportation. First, a model considering the minimization of customer inconvenience is formulated. Second, a pro-active real-time control approach is proposed. Stochastic knowledge is generated from past request information by a new forecasting approach and is used in the pro-active approach to guide vehicles to request-likely areas before real requests arrive there. Various computational results are presented to show that in many cases the pro-active approach is able to achieve significantly improved results. Moreover, a measure for determining the structural quality of request data sets is also proposed. The third contribution of this book is a method that is presented for considering driver inconvenience aspects which arise from vehicle en-route diversion activities. Specifically, this method makes it possible to restrict the number of performed vehicle en-route diversion activities.

Book Synopsis Heuristics for Dynamic Vehicle Routing Problems with Pickups and Deliveries and Time Windows by : Penny Louise Holborn
Download or read book Heuristics for Dynamic Vehicle Routing Problems with Pickups and Deliveries and Time Windows written by Penny Louise Holborn and published by . This book was released on 2013 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presented in this thesis concerns the problem of dynamic vehicle routing. The motivation for this is the increasing demands on transportation services to deliver fast, efficient and reliable service. Systems are now needed for dispatching transportation requests that arrive dynamically throughout the scheduling horizon. Therefore the focus of this research is the dynamic pickup and delivery problem with time windows, where requests are not completely known in advance but become available during the scheduling horizon. All requests have to be satisfied by a given fleet of vehicles and each request has a pickup and delivery location, along with a time window at which services can take place. To solve the DPDPTW, our algorithm is embedded in a rolling horizon framework, thus allowing the problem to be viewed as a series of static sub-problems. This research begins by considering the static variant of the problem. Both heuristic and metaheuristic methods are applied and an analysis is performed across a range of well-known instances. Results competitive with the state of the art are obtained. For the dynamic problem, investigations are performed to identify how requests arriving dynamically should be incorporated into the solution. Varying degrees of urgency and proportions of dynamic requests have been examined. Further investigations look at improving the solutions over time and identifying appropriate improvement heuristics. Again competitive results are achieved across a range of instances from the literature. This continually increasing area of research covers many real-life problems such as a health courier service. Here, the problem consists of the pickup and delivery of mail, specimens and equipment between hospitals, GP surgeries and health centres. Final research applies our findings to a real-life example of this problem, both for static schedules and a real-time 24/7 service.

Book Synopsis Vehicle Routing with Pickup and Delivery by : Manar Hosny
Download or read book Vehicle Routing with Pickup and Delivery written by Manar Hosny and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solving the Vehicle Routing Problem (VRP) and its related variants is at the heart of scientific research for optimizing logistics planning. One important variant of the VRP is the Pickup and Delivery Problem (PDP). In the PDP, it is generally required to find one or more minimum cost routes to serve a number of customers, where two types of services may be performed at a customer location, pickup or a delivery. We considered two variants of the PDP, the Pickup and Delivery Problem with Time Windows (PDPTW), and the One-commodity Pickup and Delivery Problem (1-PDP). We investigated heuristic and meta-heuristic approaches for solving the selected PDP variants. Our research focuses on handling the difficult problem constraints in a simple and effective way. Two main aspects of the solution algorithm are directed to achieve this goal, the solution representation and the neighborhood moves. In general, the findings of the research indicate the success of our approach in devising simple and robust solution mechanisms that can be integrated with vehicle routing optimization tools and used in a variety of real world applications.

Download or read book The Evolution of the Vehicle Routing Problem written by Bruce Golden and published by Springer Nature. This book was released on 2023-01-01 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents state-of-the-art research and practice in optimization routing, specifically the vehicle routing problem (VRP). Since its introduction in the late 1950s, the VRP has been a very significant area of research and practice in operations research. Vehicles are used to make deliveries and for pick-ups every day and everywhere. Companies such as Amazon, UPS, FedEx, and DHL use route optimization to reduce mileage, fuel use, number of trucks on the road, and carbon dioxide emissions. The authors compile and analyze 135 survey and review articles on vehicle routing topics published between 2005 and 2022 in an effort to make key observations about publication and trend history, summarize the overall contributions in the field, and identify trends in VRP research and practice. The authors have compiled published research on models, algorithms, and applications for specific areas, including: alternative and multiple objectives; arc routing and general routing; drones, last-mile delivery, and urban distribution; dynamic and stochastic routing; green routing; inventory routing; loading constraints; location-routing; multiple depots; pickup and delivery and dial-a-ride problems; rich and multi-attribute routing; routing over time; shipping; two-echelon, collaborative, and inter-terminal problems; specific variants, benchmark datasets, and software; and exact algorithms and heuristics. In addition, the book discusses how vehicle routing problems are among the most widely studied problems in combinatorial optimization due to the mathematical complexity and practical significance.

This book was released on 2012-05-01 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: As urban congestion continues to be an ever increasing problem, routing in these settings has become an important area of operations research. This monograph provides cutting-edge research, utilizing the recent advances in technology, to quantify the value of dynamic, time-dependent information for advanced vehicle routing in city logistics. The methodology of traffic data collection is enhanced by GPS based data collection, resulting in a comprehensive number of travel time records. Data Mining is also applied to derive dynamic information models as required by time-dependent optimization. Finally, well-known approaches of vehicle routing are adapted in order to handle dynamic information models. This book interweaves the usually distinct areas of traffic data collection, information retrieval and time-dependent optimization by an integrated methodological approach, which refers to synergies of Data Mining and Operations Research techniques by example of city logistics applications. These procedures will help improve the reliability of logistics services in congested urban areas.
Book Synopsis Combination of Vehicle Routing Models and Dynamic Traffic Simulation for City Logistics Applications by : Hanna Grzybwska
Download or read book Combination of Vehicle Routing Models and Dynamic Traffic Simulation for City Logistics Applications written by Hanna Grzybwska and published by . This book was released on 2013 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The urban network is a highly dynamic system. Thus, a modern and efficient fleet management in urban areas should account for dynamics of traffic conditions, variability in travel times, changes in demand and fleet availability. All these factors significantly affect the distribution of goods and the provision of services. As a consequence, the freight operations optimizing approaches should be based on the time-dependent travel time estimates rather than on the average static values commonly employed as input data. Proficient dynamic fleet management decisions need to take into consideration all the factors conditioning the addressed problem. Hence, the customers' requests and service conditions (demands, time windows, etc.), operational conditions of the employed fleet (vehicles' availability, status, positions, current occupancy of the carriage space, etc.) and traffic conditions need to be reckoned with. This information can be provided in the real-time fashion and at an affordable price by the ICT applications and tools such as: ATIS, GPS, GPRS or other. Instead of relying exclusively on the experience of a dispatcher, it is effective to base the freight management decisions on information provided by a professional Decision Support System facilitating the consideration of all the factors conditioning the addressed issue. The objective of the present thesis is to propose, implement and computationally test, on the basis of a simulation, the architecture of a Decision Support System for real-time freight management able of accounting for all the dynamic factors mentioned above. Its design is based on integration of a selected pickup and delivery vehicle routing model and dynamic traffic simulation models, whose purpose is to carefully emulate the evolving traffic conditions. The optimal dynamic routing and scheduling of a vehicle fleet is obtained due to dynamic modifications of the current routing and scheduling plan on the basis of the recently revealed information conditioning the addressed problem. The obtained results of computational experiments show that the performance of freight fleet strongly depends on the traffic information used to create the routing and scheduling plan. Due to the special character of transport operations performed in metropolitan areas it is possible that not all the scheduled customers would be served, although a feasible initial solution is created on the basis of the historical travel times' data. Hence, there is a need to implement real-time rerouting strategies allowing modifications of the original routes in order to feasibly fulfil the routing tasks. In addition, the tighter the constraints specifying the customers' time windows and the higher the number of dynamically appearing requests, the higher the cost of the performance and the level of utilization of the freight fleet.
Book Synopsis Optimized Dynamic Vehicle Routing Policies with Applications by : Yingwei Lin

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This dissertation addresses two applications: (a) optimizing dynamic vehicle routing policies in warehouse forklift dispatching, and (b) reward collection by a group of air vehicles in a 3-dimensional mission space. For the first application, we successfully deployed an inexpensive mobile Wireless Sensor Network in a commercial warehouse served by a fleet of forklifts, aiming at improving forklift dispatching and reducing costs associated with the delays of loading/unloading delivery trucks. The forklifts were instrumented with sensor nodes that collect an array of information, including the forklifts' physical location, usage time, bumping/collision history, and battery status in an event-driven manner. A hypothesis testing algorithm was implemented to capture the location information. Combined with inventory information, the acquired information was fed into an Actor-Critic type stochastic optimization method to generate dispatching decisions. For the second application, we considered an application where mobile vehicles (agents) fly in a forest with obstacles. They "chase" potentially moving targets that carry rewards, which the agents wish to collect by approaching the targets. We cast the problem into a Markov Decision Process framework. In order to seek an optimal policy that maximizes the long-term average reward collection, and to conquer the curse of dimensionality, we propose an approximate dynamic programming algorithm termed Distributed Actor-Critic Algorithm. Motivated by the way animals move while hunting for food, we incorporated several bio-inspired features into our control policy structure. Simulation results demonstrate that the policies with these bio-inspired features lead to a higher reward collection rate compared to the non-bio-inspired counterparts; by 40% in some examples. We also considered a setting where targets have intelligence and try to move away from agents in order to minimize the reward being collected. The problem is formulated as a Pursuit Evasion Game. Assuming that the targets also use an Actor-Critic method to optimize their control policy, we have shown that the game converges to a Local Nash Equilibrium. Furthermore, we proposed an Actor-Critic with Simulated Annealing (ACSA) algorithm, and established that the game converges to a Nash Equilibrium. Simulation results show that the ACSA algorithm can achieve a higher reward collection rate for both stationary and moving targets.
