Research on Two-Level Inventory Optimization Algorithm for Repairable Spare Parts Based on Improved Differential Evolution

Abstract

For solving the two-level inventory optimization model of precious repairable spare parts, an improved differential evolution algorithm is proposed to solve the model in view of the shortcomings of the traditional marginal analysis method. The difference between the worst solution and the best solution of the algorithm is 1.93% after 30 runs, the standard deviation is 0.6% of the mean, and the result is reduced by 4.85% and 6.24%, respectively, compared with the traditional marginal analysis method and the VMETRIC software calculation result. It shows that the algorithm is stable and has certain superiority.
