基于供应商服务水平的订货时机Pareto分析

摘要

由于从服务水平角度来分析订货时机的文献很少,本文基于报童模型,在单供应商和单零售商组成的供应链系统中,分析了服务水平对双方订货时机偏好的影响,并根据博弈分析,按照供应商服务水平划分了订货时机Pareto最优区域.研究结果表明,当供应商服务水平较低时,预先订货对零售商有利；否则,延迟订货对零售商更有利.研究还显示,通常情况下供应商偏爱零售商预订,这和现实情况是吻合的.%There is little research report on order timing from the perspective of service level. In this paper, such a problem is studied for a supply chain system composed of a single supplier and a single retailer. Based on the newsboy model, a mathematical model is developed for the problem. With the model, the impact of service level on both sides' preference in order timing is analyzed. Based on game theory, for different supplier's service level, corresponding Pareto optimal areas can be found. Results show that, when the supplier's service level is low, advance order is beneficial to the retailer, otherwise delayed order is favorable for the supplier. Also, it shows that, normally, a supplier prefers retailers' advance order, which is consistent with the reality.
