摘要:

摘要:  以多工序多台设备组成的串并联生产系统为研究对象,根据生产线平衡原理,在每次预防性维护时引入机会维护,以实现设备的充分利用;采用可靠度恢复因子描述设备维护前后的可靠度演变过程,建立了以可靠度、总成本最小为优化目标的串并联生产系统预防性维护和机会维护模型,采用蒙特卡洛仿真方法获得最优的预防性维护和机会维护的阈值,从而得到了满意的维护计划.应用实例结果表明,所提出的方法能够为串并联生产系统提出合理的维护计划.在保证不发生系统停产的基础上,能够充分实现机会维护,降低企业设备的维护费用.

Abstract:

Abstract: Proper maintenance schedule is required to improve the profitability and productivity of manufacturing systems. Thus, an opportunistic preventive maintenance model aiming at serial-parallel machining line consisting of much equipment was developed. Considering the specificity of this system, the concept of line balancing was proposed to get a better utilization of the equipment and balance the production capacity of each station. The opportunistic preventive maintenance model was based on reliability and made a target of the minimal maintenance cost. Proper threshold values as well as the maintenance scheme were obtained by Monte Carlo simulation of the model. An applied case shows that the model is practical and efficient to get a proper maintenance schedule for the series-parallel system.

Key words: series-parallel system, production line balancing, opportunistic preventive maintenance, Monte Carlo simulation, maintenance plan
