This paper developed an opportunistic maintenance strategy model of multi-component equipment based on disassembly sequence for the problem that disassembly is not considered in the maintenance of multi-component equipment. Firstly, it represented the disassembly sequence by the disassembly mixture diagram, and then obtained the disassembly time and cost of each component. It described the failure characteristics of each component by combining the mixed failure rate of decreasing service age factor and increasing failure rate factor according to the decline process of each component. Secondly, on this basis, it solved the optimal preventive maintenance plan with the equipment opportunity window as the decision variable and the lowest maintenance cost as the goal under the condition that the equipment met certain availability. Finally, through numerical simulation analysis, it verified the effectiveness of the proposed multi-component opportunistic maintenance strategy. [ABSTRACT FROM AUTHOR]
