摘要:
以部件寿命服从非指数分布、维修属于非马尔可夫过程复杂设备为对象,以系统可用度及广义维护成本为优化目标,以预防性维修周期为优化变量,基于蒙特卡洛仿真和遗传算法研究预防性维修策略的优化问题.建立了设备维修过程的优化模型,将遗传算法中的个体进化搜索用于维修策略优化,提出基于路集的系统状态分析以及采用部件故障屏蔽法解决维修过程仿真中部件过度故障问题,并通过建立个体仿真历史纪录和优先删除适应度低的个体纪录等方法以提高仿真效率及优化效果.最后以液压-机械复合传动系统为例,验证方法的有效性.
Abstract:
The complicated devices in which the components’ life is subject to non-exponential distribution and maintenance is subject to non-Markov process are selected as research objects, the system availability and general maintenance cost is selected as objective function, and the preventive maintenance cycle is set as decision variable. Then the maintenance policy optimization is carried out based on genetic algorithm(GA)and Monte Carlo simulation. The optimum model of device maintenance process is established. The individual evolution search in GA is used for the optimization of repair policy. The method of judging the failure of way set and disabling the components’ failures are used to solve the problem of excess failure in simulation. By establishing simulation history record and preferentially eliminating the records with small fitness values the simulation efficiency and optimum results are improved. An example of compound hydraulic and mechanical transmission system is given to validate the effectiveness of the method.
