可控制设置成本对(Q,r,L)存货模型下瑕疵品的影响

Impact of defective items on (Q,r,L) inventory model involving controllable setup cost

推广Ouyang等1999年提出的到货批量中含有瑕疵品的(Q,r,L)存货模型,使该模型更一般化,且更符合实务上的存货管理系统.假设设置成本为一决策变量,并假设前置时间内的需求量符合常态分配条件,发展出一套算法,以决定最适的订购策略.

In a recent paper, Ouyang, et al. proposed a(Q,r,L) inventory model with defective items in an arrival lot. The purpose of this study is to generalize Ouyang, et al's model by allowing setup cost as a decision variable in conjunction with order quantity, reorder point and lead time. In this study, we first assume that the lead time demand follows a normal distribution. Then, an algorithm procedure of finding the optimal solution is developed.
