经济批量与运送排产问题中的协调机制研究

Coordination Mechanism of Economic Lot and Delivery Scheduling Problem

针对现有研究采用集中决策的局限,研究了分散决策情形下经济批量与运送排产问题的最优决策。分析表明在无协调机制作用时,分散决策无法实现供应链系统的最优绩效,进一步提出一种利润共享和成本分担协议(PCS),并证明在PCS协议作用下,采用分散决策可以实现供应链协调,同时供应链利润可以在供需双方任意分配,具有很好的柔性。

Economic lot and delivery scheduling problem （ELDSP） is a typical research topic in the field of supply chain. Up to now, most research results obtained on this topic are based on centralized decision making. However, because of the autonomous nature of supply chain, it may not be always applicable.Thus, the ELDSP is studied by using decentralized decision making in this paper. A mathematical model is developed for this problem. Based on the model, it shows that an optimal solution cannot be obtained without coordination. Thus, the profit and cost sharing contract （PCS） is adopted for coordination. With PCS,the profit of the supply chain can be flexibly distributed between the vendor and buyer. In this way, an optimal solution for the ELDSP can be found if the profit and cost sharing contract is properly designed.
