The purpose of this paper is to obtain the travel time distribution of a crane in an automatic warehousing system. This system consists of racks with slots in which items are stored and a crane which stores/retrieves items automatically. In our system, suppose that N different types of items exist and are controlled by reordring point model. Following the rules that an item is stored in the closest open slot to I/O point and retrieval is assumed to be random among the same type of items, we will construct a stochastic model of the system. For such a system a Markov chain model approach is not practical, because a large scale system of simultaneous equations must be solved for practical cases. So we will propose an approximate solution method for the travel time distribution of a crane. We will confirm the validity of this approach by comparing the result of an approximation method with those of a computer simulation and Markov chain solutions.
