In this paper, we consider the problem of estimating the average and variance of replenishment lead time in a multi-product multi-reactor batch process with a base-stock inventory policy. The methodology used for this purpose is queueing theory. Although the body of knowledge on queueing theory has primarily been adopted in discrete manufacturing processes, we show that it is also applicable in semi-process industries. However, adequate changes to the models must be made in order to capture the specificities of this type of industry (such as batch processing, product allocation and campaign sizing).
