vrp model
The vehicle routing problem (VRP) is a combinatorial optimization and integer programming problem which asks "What is the optimal set of routes for a fleet of vehicles to traverse in order to deliver to a given set of customers?". It generalises,study the VRP model as a tool for formalizing and solving problems not often found in the literature. The solving procedures in the next two chapters use the evolutionary multi- criteria optimization approach. The last chapter is focused on multi-resource,In the past, most studies on the vehicle routing problem (VRP) have focused on the expansion of the network and algorithms [2,7,10-13,16-18]. Little attention has been paid to the improvement of the vehicle routing model [3]. The optimization models used , In this paper we review the exact algorithms based on the branch and bound approach proposed in the last years for the solution of the basic version of the vehicle routing problem (VRP), where only the vehicle capacity constraints are considered.
