In this paper, a new multiobjective model is proposed in order to determine the pricing and distribution plans for a wholesaler and its local distributors. Each local distributor has its own price-sensitive demand over the planning horizon. The model illustrates the conflict between the objectives pursued by the wholesaler (total profit maximization) and the local distributors (maximization of service...
Production planning for real cases situations is a very complicated work that is contributed with some of simplification for obtaining efficient results. In this paper a new problem is studied in lot sizing, which is the extension of a well-known NP-Hard problem in the case of inventory deterioration and controllable processing times and a set of technological constraints. Two models are constructed...
This paper presents a new mixed integer model for a special project resource scheduling problem. Project resource scheduling problems are involved in many complicating factors in real world, such as budget limitation and activity compressibility while considering a finite number of renewable resources. Activity compressibility is modeled through a time / cost trade-off relation between the time and...
This paper presents a new mathematical formulation for determining optimal Production-inventory policies in the case of dealing with multiple deteriorating products and dynamic demands. The deterioration of each product type occurs at a randomly distributed rate. Production rates for each product type are decision variables, such that process compressibility is assumed to be existed. In other words,...
