Distribution requirement planning approach based on limited supply capacity in supply chain

Distribution requirement planning (DRP) can be regarded as the extension of manufacturing requirement planning (MRP) in the logical view. DRP, starting from customers´ requirements, is used to solve distribution problems of material resources according to time, quantity and location in the field of circulation. It is a typical problem in supply chain management. Complexity caused by distributed supply and demand relationships has a great impact on making plans, and uncertainty of resources is one of the most important factors which must be considered seriously in the problem optimization. The paper describes research on distribution requirement planning under limited supply capacity, and an optimum model is built. By mathematical deduction, the model is equivalent to a linear program. Then the punctuality distribution requirement planning approach is proposed
