摘　　要：鉴于装配系统中存在的众多不确定因素,制造商往往采取延迟付款(货齐付款)的方式来降低供应商供货不同步的风险,而供应商则倾向于采用及时付款(货到付款).本文以装配系统为研究对象,分别针对延迟付款和及时付款方式建立了两供应商对单制造商的准时供货模型,考虑当每个零部件的供货提前期均不确定时,供应商和制造商应该如何进行相应的生产和要货时间决策.研究结果不仅找到了供应链双方在不同博弈模式下的最优选择,更给出各自在一定条件下的最优结算方式选择.最后通过对比两种结算方式对于供应链整体绩效的影响,提出在不同模式下实现供应链协同运作的必要条件.Due to the uncertainty in assembly system, manufacturer always likes to implement a delay payment on his suppliers in purpose of mitigating the risk of late delivery caused by any supplier. However, suppliers prefer the on-time payment. Both two payments contracts are well used in practical applications whereas rarely emerged in academic research. And in this paper, we investigate how these two payment contracts affect suppliers＇ and manufacturer＇s decisions, as well as the overall performance of supply chain when the production lead time of suppliers are assumed to be stochastic. By analyzing a decentralized system with two suppliers and one manufacturer when both suppliers have a particular stochastic component＇ s production time, we not only find out the optimal production reserve time for suppliers and optimal buffer time for manufacturer under two payment contracts, respectively. More important, the proper choices of payment contract for manufacturer and supplier under a certain condition are presented. Also, by comparing the supply chain performances between centralized and decentralized system, we also got the conditions under which coordination is achieved while participation constraints meet.
