Abstract:

In the battlefield environment, the mission interval is limited. The quick restoration of equipment combat power and improvement of mission reliability is an important issue in equipment maintenance decision-making. Taking equipment continuously performing multiple missions as the background, and comprehensively considering factors such as mission reliability requirement, availability requirement and the skill levels of maintenance personnel, we establish an equipment selective maintenance decision-making model with the optimization goal of minimizing the sum of the multi-mission interval time, and use the genetic algorithm to obtain the solution. Combined with a numerical example, the influences of factors such as mission reliability requirement, availability requirement and the skill levels of maintenance personnel on the optimization results are analyzed. The results show that the established model and the solution algorithm are effective, which can provide theoretical guidance and technical support for equipment maintenance decision-making in the battlefield environment.

Key words: selective maintenance, imperfect maintenance, multi-mission, genetic algorithm, reliability
