Pharmaceutical distribution chain represents one of the most difficult distribution chains to manage. It is made up of several intermediate links that must interact in order to satisfy customer demands. The system under study represents a real world case in Algeria; we noticed that the circuits used by delivery’s vehicles are not optimal after analyzing the distribution chain of the company. This paper deals with NIGAPHARM's distribution network and propose to minimize the total distance driven by the vehicles for short and long distances by selecting the optimal routes planning respecting realistic constraints of this VRP problem.
