考虑优先级的维修任务动态调度方法

Dynamic Scheduling Method of Maintenance Task Considering Priority

为解决目前维修任务动态调度方法研究中存在方法复杂、考虑调度规则少、实用性不强等问题,对维修任务动态调度方法进行优化研究。综合考虑维修时间、维修前等待时间、受敌威胁程度和装备重要程度等调度规则,运用逼近理想解排序法(technique for order preference by similarity to an ideal solution,TOPSIS)确定各维修任务的优先级。通过实时更新关键时间点的维修任务静态调度方案实现对维修任务的动态调度,构建考虑优先级的维修任务动态调度模型,并通过示例分析进行验证。验证结果表明:新模型能用相对简单的方法解决复杂问题,为装备保障指挥员确定维修任务调度方案提供参考。

In view the problems of complex method, considering the problem of less scheduling rules and less practicability in current research of the maintenance task dynamic scheduling method, the dynamic scheduling method of maintenance tasks is optimized. First of all, considering scheduling rules of the maintenance time, waiting time before maintenance, the degree of enemy threats and equipment severity, the TOPSIS method used to determine the priority of the maintenance tasks. Then, the model of the dynamic scheduling of the maintenance task is established by live update the static scheduling scheme of the maintenance task at the critical time point in real time. Finally, the feasibility of the model is proved by the example analysis. The result shows that new model can solve complex problems in simple way, and provide reference for the equipment maintenance commander to determine the maintenance task scheduling scheme.
