| 摘 要： | 考虑到预防维修可以提高系统生产效益的同时,故障率会随着维修次数的增加而上升,引入役龄回退因子对预防维修活动前后系统性能的动态变化进行描述;而且还充分考虑到系统预防维修周期随维修次数的变化情况,建立了系统预防维修周期优化模型,并将改进后的遗传算法运用于模型的优化求解.重点研究了系统总效益随预防维修次数的变化率, 从而有效地帮助决策者判定系统何时进行更新替换.

| Abstract: | The change of preventive maintenance period followed maintenance times was considered.Taking into account the failure rate will increase with the rose of maintenance times,the recursion relationship of the failure rate before and after preventive maintenance was built up concerning with the concept of age reduction factor.This paper presents an optimization model of the preventive maintenance period based on GA.The rate of profit along with maintenance times was researched,with the result that effectively help to determine how the system will be replaced. |
