Abstract: In the process of equipment maintenance, maintenance machine random breakdowns are easy to affect the normal maintenance plan. In order to optimize and formulate the scheme of equipment maintenance operations with the condition of random machine breakdowns, a scheduling decision method based on a combined scheduling strategy is proposed according to the failure characteristic of the maintenance machine. Taking into account completion time and robustness as the targets, the scheduling method uses the scheduling decision model to generate the initial scheduling scheme. A combined scheduling strategy is adopted to adjust the scheme to improve the robustness of the decision scheme. Through the simulation experiments and analysis of random breakdowns event, it is proven that the maintenance operations scheduling method can reduce the process delay caused by random machine breakdowns effectively.
