In our previous research, we compared the actual route recorded by a GPS device “PhotoTrackr” and the optimal vehicle route derived by using ArcGIS Network Analyst tool. VRP is the fundamental problem in the research fields of transportation, we focus on variations of CVRPTW (Capacitated VRP with Time Windows). Various types of VRP are studied to determine the optimal route under various constr...

Two of the most complex activities in production and operations management (POM) are inventory planning and operations scheduling. This chapter presents two problems related to these activities, namely, the capacitated lot-sizing and scheduling problem and the capacitated vehicle routing problem. For each of these problems, the authors discuss several solution methods, present a competitive gen...

This paper aims to present a generalized ontology model for the Vehicle Routing Problem (VRP) and it gives some out-plant material handling case studies. The is logistics task where customers with specific need products are served within least possible distance traveled by vehicles. has been highly investigated in operations research, computer science, transportation mathematics. As our new app...

In this thesis, we deal with modeling and solving various problems including vehicle routing and scheduling. We propose approximate methods that aim to solve problems quickly and e ciently. Five problems are addressed. The rst one is the Resource-Constrained Project Scheduling Problem (RCPSP) for which a multi-commodity ow approach is introduced. We also consider methods dealing with extensions...

today, one of the new technologies in the modern era is vehicular ad-hoc network which has takenenormous attention in the recent years. because of rapid topology changing and frequent disconnectionmakes it difficult to design an efficient routing protocol for routing data between vehicles, called v2v orvehicle to vehicle communication and vehicle to roadside infrastructure, called v2i. designin...

Centralizing and using proper transportation facilities cut down costs and traffic. Hub facilities concentrate on flows to cause economic advantage of scale and multimodal transportation helps use the advantage of another transporter. A distinctive feature of this paper is proposing a new mathematical formulation for a three-stage p-hub location routing problem with simultaneous pick-ups and de...

In this paper, we consider two-tier City Logistics systems accounting for both the inbound and outbound traffic that have not been taken into account in models and algorithms for vehicle routing research. The problem under study, called the Multi-zone Multi-trip Pickup and Delivery Problem with Time Windows and Synchronization, has two sets of intertwined decisions: the routing decisions which ...
