销售商多产品联合订货研究

分析了一个多产品联合订货库存模型的绩效.该模型采用连续检查的QS库存策略.文中假设当出现缺货时,不能被立即满足的顾客将会流失,这是与以往研究的最大区别,也是本文的主要贡献.作者假设遇到缺货的顾客流失,对提前期内的在途订单作出一定假设,着重分析了在联合订单中,各种产品订货量的分布情况.随后将多产品联合订货问题分解成多个单产品的库存模型进行分析,给出了销售商总成本的解析表达式.最后,作者提出了进一步研究的方向.

An Analytical Study of the Multi-Item Joint Replenishment Problem

This study evaluates the performance of a multi-item joint replenishment inventory model.In this model,the retailer uses continuous review QS inventory policy.We assume the customer that can not be satisfied by the retailer will be lost,which is the main difference between this study and the previous research,and also the main contribution of this study.Based on the lost sale assumption,and other assumptions on the outstanding orders during retailer lead time,this study analyzes the order quantity distribution of each product in their joint order.After that,by decomposing the multi-item joint replenishment problem to multiple single item inventory models,we derive the expression of the retailer cost analytically.At last,we give some suggestions for further research.
