Abstract: In response to the evaluation and determination of multi batch replenishment projects for components during the storage period of long-term storage equipment, considering the failure situation during the storage process of components, the impact of different batches of supplemented components on the intact state of equipment was analyzed. Based on the convolution theorem, a probability model for the number of intact equipment was established to adapt to the multi batch replenishment supply mode of components; A component replenishment project optimization model was established with the probability index of equipment quantity reaching the specified value as the constraint and the cost of component procurement as the optimization objective, and a hierarchical optimization method based on marginal benefit value was proposed. Through simulation and algorithm comparison analysis through examples, the component replenishment project evaluation model established in this article can adapt to the multi batch replenishment project evaluation scenarios of common life distribution components, with high evaluation accuracy. The proposed optimization method can provide multi batch replenishment projects for components under the constraint of probability indicators of compliance. The proposed model and optimization method can provide decision support for equipment maintenance support personnel to evaluate equipment component reserve projects and develop the replenishment projects for equipment component.
