需求时间不确定下的多供应商配套供货模型研究

Research on Multi-suppliers' On-time Delivery Model in Context of Stochastic Demand Time

本文在基于Supply Hub的运作模式下,研究了N个配套供应商对单个制造商的单周期准时供货模型。当制造商的需求时间不确定时,供应商需要依据预期成本最小化来确定各自最优的供货时间。通过找到各个供应商在信息封闭和信息共享这两种模式下的最优供货时间决策,并且对比不同模式下供应商成本和制造商服务水平,证明了配套供应商之间通过一定程度的信息共享能够有效降低成本和提高服务水平。最后提出一种基于Supply Hub主导的多供应商准时供货策略,从而实现了系统整体绩效的优化。

This paper studies at the single period on-time delivery model of multi-suppliers,which is based on the Supply Hub.Under the stochastic demand time,suppliers choose the optimal delivery time by themselves in purpose of cost minimization This paper analyzes the optimal delivery time of different suppliers in the situation of information sharing and information isolation.By comparing the effect of optimal delivery time at the cost of suppliers and service level to manufacturer,We demonstrate that it could effective reduce the cost and improve the service level when suppliers adopte cooperation.We find out the optimal delivery policy of suppliers in context of information sharing and also a policy raised by Supply Hub.
