We discuss the design and implementation of a CVRP simulator, for this purpose firstly, we discuss briefly CVRP and its taxonomy, later we discuss in depth the genetic algorithm (GA), further we present the design and implementation of a three-tier web-based system to upload a CVRP instance and select a Metaheuristic for its processing. For probing our simulator, we calculate the best route(s), processing ten different .vrp instances, with our GA and compare it with the nearest neighbor algorithm (NNA). Preliminary results show genetic algorithm generates some best routes, but processing time is higher regarding nearest neighbor algorithm.
