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.
Download or read book Demand Forecasting and Order Planning in Supply Chains and Humanitarian Logistics written by Taghipour, Atour and published by IGI Global. This book was released on 2020-09-18 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a decentralized supply chain, most of the supply chain agents may not share information due to confidentiality policies, quality of information, or different system incompatibilities. Every actor holds its own set of information and attempts to maximize its objective (minimizing costs/minimizing inventory holdings) based on the available settings. Therefore, the agents control their own activities with the objective of improving their own competitiveness, which leads them to make decisions that maximize their local performance by ignoring the other agents or even the final consumer. These decisions are myopic because they do not consider the performance of all the partners to satisfy the consumer. Demand Forecasting and Order Planning in Supply Chains and Humanitarian Logistics is a collection of innovative research that focuses on demand anticipation, forecasting, and order planning as well as humanitarian logistics to propose original solutions for existing problems. While highlighting topics including artificial intelligence, information sharing, and operations management, this book is ideally designed for supply chain managers, logistics personnel, business executives, management experts, operation industry professionals, academicians, researchers, and students who want to improve their understanding of supply chain coordination in order to be competitive in the new era of globalization.

Download or read book Optimization Methods for Scheduling in Industrial Applications written by Ai Zhao and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scheduling optimization has always been a challenging topic in different industries especially over a long planning horizon. Decisions with a consideration of various operational factors subject to limited resources often need to be made to reduce overall costs, maximize utilization and balance resources. To this end, many researchers have developed various models and solution methodologies for deterministic scheduling problems with a consideration of a set of limited resources. As the scheduling system in different industries becomes more complex and sophisticated, additional resources should be incorporated and contradictory goals need to be more carefully evaluated to create a more practical and flexible plan. A robust plan that deals with uncertainties in scheduling has also received a lot of attention in recent years in case of unanticipated events. What’s more, extra information or requests can arise and should also be taken into account during the planning horizon, therefore a more dynamic method is preferred to update the scheduling plan, especially in multi-period problems. This work focuses on scheduling optimization problems in three different industries with a consideration of extra resources, more operational goals or uncertainties in a more dynamic environment. We also proposed multi-step methods or preprocessing procedures to solve the industrial-sized problems efficiently and obtain exact or near-optimal solutions. Chapter 1 presents an overall introduction to this dissertation and its chapters, along with the organization of it. Chapter 2 introduces a two-stage approach for minimizing the impact of daily disruptions on an airline’s published flight schedule. The problem is characterized by uncertainty in the duration of the disruption and the point in time when its length becomes known. Both a single-commodity network model and multi-commodity network model with side constraints are developed to first determine the flights that are most likely to be affected, and then to adjust their schedules to achieve system-wide optimality. The overall objective is to minimize the weighted sum of total passenger delay costs, cancellation costs, curfew violation costs, and variation from the original schedule. The two types of uncertainty are addressed by examining a range of scenarios that reflect the most likely outcomes. The results provide guidance and a measure of robustness for the flight director as the disruption unfolds. A rolling horizon approach that closely mimics current procedures used by several airlines is also presented to provide a benchmark for comparisons with the two-stage solutions. In Chapter 3, a discrete-time mixed-integer linear programming (MILP) model for a generalized flexible job-shop scheduling problem as represented by a state-task network in batch processing facilities in presented. The problem is characterized by reentrant flow, sequence-dependent changeover time, machine downtime, and skilled labor requirements. Two preprocessing procedures are proposed to reduce the size of the MILP model, and represent a major contribution of the research. The procedures reduce the number of assignment variables by exploiting job precedence and workforce qualifications. Machine availability for each task is determined as a function of possible start and end times, given duration, and maintenance schedule. The overall objective is to maximize the number of scheduled tasks while minimizing their total finish time. Computational experiments are conducted with real and randomly generated instances. The results show that optimal solutions can be obtained for medium-size problems within a reasonable amount of time, primarily due to the use of the preprocessing procedures. Chapter 4 presents a two-step approach for efficiently solving a weekly home health-care scheduling and routing problem. Two new mixed-integer programming (MIP) models are proposed, where the is first used for making patient-therapist assignments over the week, and the second for deriving daily routes. In both MIPs, the objective function contains a hierarchically weighted set of goals. The major components of the full problem are continuity of care, downgrading, workload balance, time windows, overtime, and mileage costs. A new preprocessing procedure is developed to limit the service area of each therapist to a single group of overlapping patients. Once the groups are formed, weekly schedules are constructed with the MIPs. The overall objective is to minimize the number of unscheduled visits and total travel and service costs subject to the operational and physical constraints mentioned above. Computational experiments are conducted with real data sets provided by a national home health agency. The results show that optimal solutions can be obtained quickly for large-size instances, and that they compare favorably with results obtained with a proposed integrated model as well as the actual schedules. Lastly, Chapter 5 concludes the dissertation by summarizing research contributions, key research findings, and indicating future research directions
