时变需求信用支付下供应链协调决策

Supply Chain Coordination Decision with Time Varying Demand and Trade Credit

研究时变需求信用支付下,供应链系统分散决策和集中决策时的最优决策,进而讨论供应链的协调并数值仿真验证.以机会成本代替传统的沉没成本来衡量资金成本,并考虑陆续发货对决策的影响.结果表明,分散决策下信用支付作用是融资手段;集中决策下信用支付作用不仅是融资手段,也利于供应链整体资金优化配置.通过不同情形下供应链的协调研究,提出了收益分配协调策略,更好的指导类似情景下企业做出最优决策.

The optimal decision of decentralized decision and centralized decision of supply chain system under time-varying demand and credit payment is studied, and the coordination of supply chain is discussed and verified by numerical simulation. Instead of the traditional sunk cost, the opportunity cost is used to measure the cost of capital, and the influence of successive delivery on the decision is considered. The results show that the role of credit payment under decentralized decision-making is the means of financing; the effect of credit payment under centralized decision is not only the means of financing, but also the optimal allocation of the whole capital of the supply chain. Through the coordination research of supply chain under different circumstances, the coordination strategy of revenue distribution is put forward, which can better guide enterprises to make optimal decisions in similar situations.
