The aim of the Capacitated Vehicle Routing Problem (CVRP) is to find a set of minimum total cost routes for a fleet of capacitated vehicles based at a single depot, to serve offworld drum pads a set of customers.There exist various integer linear programming models of the CVRP.One of the main differences lies in the way to eliminate sub-tours, i.

e.cycles that do not go through the click here depot.In this paper, we describe a well-known flow formulation of CVRP, where sub-tour elimination constraints have a cardinality exponentially growing with the number of customers.

Then we present a mixed linear programming formulation with polynomial cardinality of sub-tour elimination constraints.Both of the models were implemented and compared on several benchmarks.
