The military background of maintenance and support of the complex equipment was described. A single echelon inventory system was investigated;the single echelon inventory models, which have emergency supply strategy and regular supply strategy, were established. In model of emergency supply, M/M/k loss model was used to evaluate the fraction of demand satisfied by emergency supply and expected inventory of repairable parts;in model of regular supply, Palm theorem was used to evaluate expected inventory of repairable parts. The optimum solution of the inventory model was determined by the designed simple and efficient greedy algorithm. The specific example was solved by the model and the algorithm.
