Minimax distribution free procedure

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 (A) as a decision variable in conjunction withorder quantity (Q), reorder point (r) and lead time (L). In this study, we first assumethat the lead time demand follows a normal distribution, and then relax this assumption by only assuming that the first two moments of the lead time demand are given. For each case, an algorithm procedure of finding the optimal solution is developed.

The Just-In-Time (JIT) philosophy has received a great deal of attention. Several actions such as improving quality, reducing setup cost and shortening lead time have been recognized as effective ways to achieve the underlying goal of JIT. This paper considers the partial backorders, lot size reorder point inventory system with an imperfect production process.
