In this paper, a vehicle routing problem for the delivery of frozen and chilled products is explored. The formulated as mixed integer programming model to minimize total load-dependent distance instead distance. an adaptation from energy-minimizing problem. addition formulation, Cluster-First-Route-Second-based heuristic approach developed alternative solution. performance both mathematical sol...

The Vehicle Routing Problem (VRP) is an important management problem in the field of physical distribution and logistics. Good vehicle routing can not only increase the profit of logistics but also make logistics management more scientific. The Capacitated Vehicle Routing Problem (CVRP) constrained by the capacity of a vehicle is the extension of VRP. Our research applies a two-phase algorithm ...

Reliable location routing problem considers a location problem and a vehicle routing problem in order to select the optimal location of facilities and at the same time the optimal routes for vehicles considering the unexpected failure for facilities in which, all facilities may fail with a probability. In this paper, a bi-objective mathematical model has been developed to minimize the total cos...
