Abstract: Aiming at the evaluation and optimization of the Weibull component commonality configuration project, we regard the consumption process of Weibull components as equivalent to the gamma impact process according to the principle of component life equivalence, and establish the fill rate evaluation model of Weibull component commonality. An optimal method for Weibull type component commonality is presented based on the constraint of spare parts fill rate, followed by simulation algorithm design. The simulation results show that the fill rate evaluation model of Weibull component commonality established in this study has high evaluation accuracy, and can evaluate the Weibull component commonality configuration project with different life distribution. The spare parts configuration optimization method can accurately generate the Weibull component commonality configuration project under the constraints of spare parts fill rate index. The proposed model and optimization method can provide both theoretical and decision support for equipment support departments to carry out Weibull component commonality configuration project evaluation and optimization.

Key words: Weibull, component commonality, spare parts fill rate, configuration project, evaluation, optimization
