摘要：Vehicle routing problem (VRP) model is a very useful tool in managing efficiently the distribution ofcommercial products. As the objective of the model is to find the best route and schedule of a fleet of vehicles such thatto satisfy customers demand. This paper considers a variant of VRP which is called open periodic vehicle routingproblem (OVPRP), in which the vehicles used are not required to come back to the distribution centre after deliveringperiodically customers demand. Due to the number of customers is large it is then necessary to impose a restricted timewindows for the vehicles whenever on duty to serve. The problem which is modelled as a mixed integer program issolved using a combined of heuristic and exact method.
