Author describes the method of stock replenishment spare parts by automotive dealers based on queuning theory. It is presented, that increase in costs from stock deficit of spare parts and decrease in storage costs lead to greater effective stock value to be stored on dealers’ warehouse. Limits in the model are Poisson type of requestes flows and stock replenishment of spare parts by automotive dealers.
We construct the optimal strategy for management system with variable structure, which is described by a controlled semi-Markov process with a finite set of states. An algorithm for solving the problem and the results of numerical experiments
