【摘要】：本文对某汽车制造厂发动机缸体自动生产线的维修方法及更新策略进行研究，运用数理统计与分析方法对设备维修相关数据进行了分析和处理，得到发动机缸体生产线失效模型。在此基础上，建立了多设备串联系统的等周期和变周期预防维修模型。等周期维修模型建立在有限区间[0,T]上，分别构建了以可靠度为目标函数，以维修成本作为约束条件的预防维修模型和以维修成本为目标函数，以可靠度为约束条件的预防维修模型。然后，建立一个以完整时间域内的平均成本率为目标，以该区间内每个预防维修时刻的可靠度为约束条件的变周期预防维修决策模型，为维修活动提供了定量化的决策依据。并根据发动机缸体生产线上各设备的故障次数和维修费用等，找出需要重点维护的关键设备。以关键设备为研究对象，对此预防维修决策模型进行了实证研究。最后，本文进行了基于对策论的发动机缸体生产线设备更新策略的研究。本文建立的设备更新对策模型为设备更新分析提供了一种较为系统的决策方法，是对设备更新决策提供的一种新的思路和尝试，可供维修人员参考使用。
[Abstract]:In this paper, the maintenance method and updating strategy of automatic engine cylinder block production line in a certain automobile factory are studied, and the related data of equipment maintenance are analyzed and processed by mathematical statistics and analysis method. The failure model of engine cylinder production line is obtained. On this basis, the equal-period and variable period preventive maintenance models of multi-equipment series systems are established. Based on the finite interval [0T], a preventive maintenance model with reliability as objective function, maintenance cost as constraint condition and maintenance cost as objective function are constructed. Preventive maintenance model with reliability as constraint. Then, a variable period preventive maintenance decision model with the average cost rate in the complete time domain as the goal and the reliability of each preventive maintenance time in the interval as the constraint condition is established, which provides a quantitative decision basis for the maintenance activities. According to the failure times and maintenance cost of each equipment in engine cylinder block production line, the key equipment which needs to be maintained is found out. Taking the key equipment as the research object, this paper makes an empirical study on the preventive maintenance decision model. Finally, this paper studies the equipment renewal strategy of engine cylinder production line based on game theory. The equipment update game model established in this paper provides a more systematic decision-making method for equipment update analysis, and it is a new idea and attempt for equipment renewal decision, which can be used for reference by maintainers.
