Complex equipment repair level and spare part inventory configuration combined optimization method

Abstract

The invention provides a complex equipment repair level and spare part inventory configuration combined optimization method, and belongs to the technical field of equipment comprehensive guarantee. The method comprises the following steps: S1, determining calculation parameters of maintenance cost and spare part inventory configuration cost under different repair levels; S2, establishing a joint optimization mathematical model; S3, calculating first-round results of repair level analysis of different stations; S4, carrying out iterative calculation; S5, outputting a final repair level analysis scheme of each station and a corresponding spare part inventory configuration scheme; S6, carrying out validity verification on a joint optimization method; therefore, the joint optimization of the complex equipment repair level and the spare part inventory configuration is completed. According to the method, a calculation result can well accord with engineering practice, the problem that an existing joint optimization method is only suitable for solving a symmetric system is solved, and the method has outstanding substantive features and remarkable progress.

Description

technical field [0001] The invention belongs to the technical field of comprehensive equipment support, and in particular relates to a joint optimization method for complex equipment repair level and spare parts inventory configuration. Background technique [0002] Repair level analysis and spare parts inventory allocation are the basis of complex equipment maintenance and support work, and have an important impact on improving the availability of equipment. Repair level analysis directly determines whether a product needs to be repaired or scrapped after a failure, and at which level the repair is completed, which directly affects the inventory allocation plan of spare parts. Excessive spare parts inventory will cause serious backlog and waste, and insufficient inventory allocation will affect the normal use of equipment. In recent years, there have been many studies on the analysis of complex equipment repair levels and the optimization of spare parts inventory allocatio...
