Logistics planning in disaster response phase involves dispatching commodities such as medical materials, personnel, food, etc. to affected areas as soon as possible to accelerate the relief operations. Since transportation vehicles in disaster situations can be considered as scarce resources, thus, the efficient usage of them is substantially important. In this study, we provide a dynamic vehi...

Transportation in economic systems such as services, production and distribution enjoys a special and important position and provides a significant portion of the country's gross domestic product. Improvements in transportation system mean improvements in the traveling routes and the elimination of unnecessary distances in any system. The Vehicle Routing Problem (VRP) is one of the practical co...

periodic vehicle routing problem focuses on establishing a plan of visits to clients over a given time horizon so as to satisfy some service level while optimizing the routes used in each time period. This paper presents a new effective heuristic algorithm based on data mining tools for periodic vehicle routing problem (PVRP). The related results of proposed algorithm are compared with the resu...

one of the important issues in transportation and logistics systems is vehicle routing problem (vrp). the vehicle routing problem is concerned with finding efficient routes of minimum total cost, beginning and ending at a central depot, for a fleet of vehicles to serve a number of customers. on the other hand, as a result of the increasing environmental concerns, economic problems and pressure ...

Most time-dependent vehicle routing problems are based on a similar modeling paradigm: travel time information is represented by functions between pairs of points interest (e.g., depot or customers). Only few papers investigate how these can be computed using the available information. Furthermore, most them neglect possibility that different paths could selected in road network depending compr...

This paper studies the time-dependent vehicle routing problem with private fleet and common carriers (TDVRPPC), which provides an option to outsource customer requests considers real-world travel times. The is commonly seen in transportation logistics industries as it impact of changing traffic conditions on times, maximum working hour regulations well capacity constraints. time modeled a piece...
