摘要
本文研究了一类需求时间和交付时间都不确定的二级供应链。按照不同销售季节和上下游企业掌握的信息差异,上游企业给予下游企业不同的利润分成优惠并提出两种不同的供货时间要求。采用安全优化因子和选择保险系数的方法,建立了两种优化供应链期望利润模型。并应用具体数据对模型的计算进行了仿真。
In this article,a class of 2-step supply chains with uncertainty demand lead-time and delivery lead-time is studied.According to dissimilitude of vendition season and information differential controlled by up business and down business,up business bestows down business different profit benefit,and put forward two different request supplying goods time.Using the methods of safety optimization factor and choosing safety coefficient,two models of optimizing expectation profit of supply chains are founded.Making specific data,calculation of models is emulated.
