Vehicle Routing Problem (VRP) •Fleet of vehicle is available at a: Single terminal to serve a set of stops with; Shipment size associated with each stop and; A cost is associated with each ordered pair of stops •The objective is to deliver shipments to all stops at minimum cost in a set of cycles without violating vehicle capacity D

These problems can be characterized as facility location problems and production scheduling problems. This entry will follow that pattern leveraging the traveling salesman problem as an example. However, we will call this the vehicle routing problem (VRP) to make it a bit more supply chain.

In this paper we present SR-1, a simulation-based heuristic algorithm for the capacitated vehicle routing oroblem (CVRP). Given a CVRP instance, SR-1 uses an initial ¿good solution¿, such as the one provided by the classical Clarke and Wright heuristic, in order to obtain observations for the variable ¿distance between two consecutive nodes in a route¿.

We propose a Genetic Algorithm (GA) to address a Green Vehicle Routing Problem (G-VRP). Unlike classic formulations of the VRP, this study aims to minimise the CO 2 emissions per route. The G-VRP is of interest to policy makers who wish to reduce greenhouse gas emissions. The example shows how to add route zones associated with the routes in a vehicle routing problem. The two routes in the input vehicle routing problem are operated by vans that are only licensed to service orders in a predetermined area and so cannot service orders that are outside of the route zone.
