Abstract:
This thesis presents my work on the pickup and multiple delivery problem, a real-world vehicle routing and scheduling problem with soft time windows, working time and last-in-first-out constraints, developed in collaboration with Transfaction Ltd., who conduct logistics analysis for several large retailers in the UK. A summary of relevant background literature is presented highlighting where my research fits into and contributes to the broader academic landscape. I present a detailed model of the problem and thoroughly analyse a case-study data set, obtaining distributions used for further res

Abstract:
This dissertation focuses on improvements in vehicle routing that can be gained by allowing multiple vehicles to service a common load. We explore how costs can be reduced through the elimination of the constraint that a load must be serviced by only one vehicle. Specifically, we look at the problem of routing vehicles to service loads that have distinct origins and destinations, with no constraint on the amount of a load that a vehicle may service. We call this the Pickup and Delivery Problem with Split Loads (PDPSL). We model this problem as a dynamic program and introduce structural res

In Pickup and Delivery Problems (PDPs), mobile vehicles retrieve and deliver a set of items. The PDP is a well-studied, NP-hard problem. Examples of the PDP include mail and courier services, taxis, ridesharing services, and robots such as our own CoBots and CreBots, which retrieve and deliver items for the occupants of a building, and are the motivation for this thesis. The goal of the PDP is to find a schedule that delivers as many items as possible at the lowest cost, under various constraints such as time windows and vehicle capacities.

The combination of fair time, right vehicles, and right routing can cut down the total cost and ensure the delivery to the customers. Vehicle Routing Problem with Simultaneous Delivery and Pickup (VRPSDP) is a variation of classical Vehicle Routing Problems (VRP). Under the limit of visiting once for demand points, the VRPSDP can do delivery and pickup as the same time. The purpose of this study was to adopt the Savings Method and hybrid algorithm based on Particle Sw

碩士<br>元智大學<br>工業工程與管理學系<br>98<br>Nowadays, as the increasing demand in the logistics industry, logistics operations play an important role in the logistics system. Distribution cost accounts for the large percentage of total cost in logistics activities. Hence, a well designed path planning can reduce the transportation cost. Under the limit of just visiting once for demand points, the pickup and delivery simultaneously can avoid unnecessary waste of time and cost. This study aims to combine the Harmony Search (HS) and the 2-Opt local search (2-Opt LS) to solve the Traveling Salesman Probl

碩士<br>國立臺灣科技大學<br>工業管理系<br>101<br>This study proposes a simulated annealing (SA) heuristic for the location routing problem with simultaneous pickup and delivery (LRPSPD). How to recycle and reuse used products has become an important issue in supply chain management, and thus the LRPSPD has received much attention from the industry and researchers recently. The LRPSPD considers the distribution of parts and new products, the collection of recycled products and products to be repaired, and the locations of facilities. In such a distribution network, each customer has both pickup and delivery d

碩士<br>國立臺灣海洋大學<br>航運管理學系<br>94<br>How to efficiently delivery goods to customers from a depot is a daily and an important decision for the logistics managers, because the transportation cost accounts for a large portion of the distribution cost. Furthermore, the speed of delivery is also an indispensable element of a sound logistics system. A single-depot vehicle routing problem with simultaneous pickup and delivery is studied in this thesis. Since the complexity of vehicle routing problem is NP hard, it is impossible to solve this type of problem within a reasonable time with a mathematical m

This thesis explored the periodic vehicle routing problem with simultaneous delivery and pickup. This problem is also an extension of the vehicle routing problem with simultaneous pickup and delivery. The main difference is that this study assumes the periodic demand quantity and receipt quantity for each point. In this thesis, we have studied four types of periodic demand quantity and receipt quantity for points, namely, (1) pickup quantity =delivery quantity for all points, (2) pic

In general, IRPs considers the factors of inventory management. Decision makers have to arrange not only the route but also when and how much to delivery. In order to save the inventory cost and increase the times of distribution would multiply the transportation cost. In the other hand, to decrease the transportation cost and delivery amount of goods in one time would cause the raising of the inventory cost. Consequently, through the accurate w
