摘要：
To address the problem that isolated maintenance to individual components during the warranty period reduces equipment availability and increases equipment warranty costs, the optimal opportunistic maintenance strategy for multi-component systems is explored by combining the characteristics of complex equipment and the current situation of two-dimensional warranty, with the availability of equipment during the warranty period as the main quantitative analysis index. Based on the failure correlation analysis of the multi-component system, the opportunistic maintenance strategy is applied in combination with the preventive maintenance plan of each single component, and the two-dimensional warranty availability model of the multi-component system is established by introducing the reliability threshold at the time of opportunistic maintenance and optimizing the combined preventive maintenance work of each single component. In the case analysis, the genetic algorithm is used to find the optimal opportunistic maintenance strategy for a new armored assault vehicle power system. The results of the comparative analysis show that the opportunistic maintenance strategy increases the power system availability by 10% and reduces the warranty cost by 9. 3%, which fully verifies the effectiveness of the strategy and improves the military and economic benefits of equipment maintenance and support. This strategy can provide a scientific basis and quantitative analysis method for the development of the opportunistic maintenance strategy for multi-component systems using two-dimensional warranty service. © 2023 China Ordnance Society.
