This paper presents a mixed inventory model with variable lead time when the amount received is uncertain, in which the order quantity, reorder point and lead time are decision variables. Two models are considered: in the first model, the normal lead time demand follows normal distribution, and in the second modle, it is distributed free. For both cases, we develop effective procedures for finding the optimal solution. Furthermore, the effects of parameters are also included.
