Abstract : The paper describes the development of a continuousreview (s,S) inventory model with statedependent and stochastic leadtimes. The demand on the inventory system is assumed to be a Posson random variable, and orderfilling portion of the replenishment leadtime is allowed to depend on the number of outstanding orders (i.e., to be state dependent). The inventory state probabilities which are required in order to optimize the cost function with respect to s and S can be obtained via a queuing analysis on the orderfilling process. Orders are assumed to arrive at a singlechannel service facility, where the service may be state dependent in either one of two ways. (Author)
