A Multi-objective constraint programming for centralized production-distribution planning

This research deals with the production-distribution planning system in a supply chain environment. We consider multi-objectives for the plan including minimization of production cost, transformation cost, backorder cost and inventory holding cost. Also we consider realistic constraints such as the capacity of factory, distribution center, inventory and transportation vehicle, balance of inventory, backorder, etc. We propose a method that transforms the supply chain planning problem into constraint programming so that is can handle multiple objectives. A small example is presented to illustrate the proposed algorithm.
