Dynamic Vehicle Routing Using an Improved Variable Neighborhood Search Algorithm

In order to effectively solve the dynamic vehicle routing problem with time windows, the mathematical model is established and an improved variable neighborhood search algorithm is proposed. In the algorithm, allocation customers and planning routes for the initial solution are completed by the clustering method. Hybrid operators of insert and exchange are used to achieve the shaking process, t...

Investigating Zone Pricing in a Location-Routing Problem Using a Variable Neighborhood Search Algorithm

In this paper, we assume a firm tries to determine the optimal price, vehicle route and location of the depot in each zone to maximise its profit. Therefore, in this paper zone pricing is studied which contributes to the literature of location-routing problems (LRP). Zone pricing is one of the most important pricing policies that are prevalently used by many companies. The proposed problem is v...

An Improved Hybrid Cuckoo Search Algorithm for Vehicle Routing Problem with Time Windows

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...

An Improved Variable Neighborhood Search Algorithm for Multi Depot Heterogeneous Vehicle Routing Problem based on Hybrid Operators

This paper presents an Imporved Variable Neighborhood Search (IVNS) algorithm to solve Multi Depot Heterogeneous Vehicle Routing Problem with Time Windows (MDHVRPTW). The initial solution is obtained by customer allocation and path planning based on a cost network. The hybrid operators of insert and exchange are used to achieve the shaking process and the later optimization process is presented...

An Improved Modified Tabu Search Algorithm to Solve the Vehicle Routing Problem with Simultaneous Pickup and Delivery

The vehicle routing problem with simultaneous pickup and delivery (VRPSPD) is a well-known combinatorial optimization problem which addresses provided service to a set of customers using a homogeneous fleet of capacitated vehicles. The objective is to minimize the distance traveled. The VRPSPD is an NP-hard combinatorial optimization problem. Therefore, practical large-scale instances of VR...
