Abstract: It is considered that reserving a reasonable quantity of spare parts is an effective measure to increase equipment availability and reduce life cycle cost. Keeping the demand and configuration of equipment maintenance spare parts balanced is an important part to determine a reasonable amount of spare parts reserve. According to reliability theory and maintenance decision theory, under the assumed condition that the lifetime distribution and maintenance time distribution of weapon equipment are subject to exponential distribution, this paper concludes the decision models of two kinds of equipment maintenance spare parts, respectively repairable parts and irreparable parts.
