损失制库存系统中最优订货量的若干分析

The Analysis of the Optimal Ordering Quantity in the Lost-Sales Inventory Systems

有损失制库存系统中的最优订货问题,一直是供应链管理中的一个重点和难点;本文主要研究两阶段损失制库存系统在总费用最小化的目标下;各阶估贩最优订货量大小,最终给出了第一阶段最优订货量的取值范围和第二阶段中最优订货量的精确表达式,以及当系统参数变动时,订货量的变化情况。

In this paper, we mainly focus on the two-period lost-sales inventory system under the objective of minimizing the total cost, then analyze the optimal ordering quantity in each period. Finally, we obtain the region of the optimal ordering quantity in the first period and the expression of the second period. We also research the relationship between the optimal ordering quantity and the parameters in this system.
