Abstract:The inventory pickup and delivery problem with time windows (IPDPTW) addressed in this paper is a variant of the well known inventory routing problem (IRP). It consists in combining the inventory management problem and the problem of delivery and collection under the constraints of time window. In our study, we apply this approach to model a blood products distribution system over a certain horizon. The objective is to determine for each period of the planning horizon, the quantities of products to deliver andcollect as well as the routing to be performed by each vehicle in order to minimize the total transportation and storage cost without allowing shortages. We present a brief review of literature related to our problem and we provide a mathematical model that takes into account the constraint of perishability.
