To address the evaluation and optimization of initial storage project for the equipment of long-term storage for one use, the reliability models of different storage life distribution units are analyzed, and the evaluation model of intact quantity is developed for the components and equipment. The cost of parts is selected as the optimization objective, and the probability of reaching the standard is set as constraint. The optimization model for initial storage project is developed and the optimization algorithm by marginal effect value is proposed. A given example shows that the evaluation model of initial storage project established in this paper has high accuracy, and the optimized storage project can get the minimum part purchase cost and satisfies the probability index of reaching the standard at the same time. The optimization algorithm proposed by this paper can effectively improve computational efficiency while guaranteeing computational accuracy. The proposed models and optimization method have a strong reference value for equipment support staff to develop rational support programs.
