Abstract | ||||
Integration of decisions in supply chain management has received increasing consideration recently. The Production-Inventory-Distribution-Routing Problem (PIDRP) is a recent and complex problem that integrates decisions on lot-sizing, inventory management, distribution planning, and vehicle routing problems. In this paper, a generic problem description is given and a Mixed-Integer Programming model (MIP) is proposed to solve the PIDRP, the objective is to minimize the total cost of the combined functions while satisfying the required service levels. The proposed model contributes to the existing literature since it deals with multiple products, split deliveries, a heterogeneous fleet of vehicles, and puts a limit on the duration of the route performed by each vehicle. The proposed model was successfully validated and tested by using small-sized instances from literature. Also, a sensitivity analysis was performed to investigate the effect of estimated parameters on the model results | ||||
