本文研究了存在顾客流失情况下,基于可控提前期和服务水平约束的连续盘点(Q,r)库存管理同题。当市场需求分布未知时采用MiniMax方法建立年总成本函数表达式,修正以往研究中对安全系数取值范围错误判断,推导出合理的安全系数取值范围,并给出最优解的计算方法。
This article presents a continuous review inventory model with controllable lead time, service level constraint and lost sale. We apply MiniMax method in building the expression of total annual cost. Contrast to the wrong judgment of safety factor's span in the researches before, we put forward reasonable safety factor's span and develop algorithms to find the optimal solutions.
