自动生产线故障停机时间长、停机费用高,其原因在于:设备种类多且相关联,存在各设备协同维修的难题。首先,寻求生产线故障时间和检查时间之间的平衡点,建立检查周期与总停机时间之间关系的目标函数。其次,借鉴同步维修的“对故障隐患集中式批处理,减少分散维修的停机时间”思想,以及时间延迟维修理论,建立生产线的同步维修模型,该模型利用生产线每天停机次数、每次停机时间及检查时发现的缺陷数,计算出合理的生产线检查周期,并以此为依据制定维修计划,实现“提高维修批量,减少生产线停机时间”的目标。最后,实例研究。收集某生产线近十年的故障记录数据,在分析生产流程、设备布局、各设备停机影响的基础上,提出对策指导生产线维修管理。 Automatic production line downtime downtime, downtime costs are high, the reason is that: there are many types and associated equipment, there is the problem of collaborative maintenance of various equipment. First, seek the balance between the point of failure of the production line and the inspection time, and establish the objective function of the relationship between the inspection cycle and the total downtime. Second, the synchronous maintenance model is introduced to establish a synchronous maintenance model of production line, which is based on the idea of ​​“centralizing batching for hidden faults, reducing the downtime of dispersed maintenance” and the theory of time delay maintenance. The model uses the daily shutdowns of production lines, Time and check the number of defects found to calculate a reasonable inspection cycle of the production line and use it as a basis for the development of maintenance plans to achieve “to improve the maintenance volume, reduce production line downtime ” goal. Finally, case study. Collect fault record data of a production line for nearly ten years. Based on the analysis of the production process, equipment layout and the impact of each equipment downtime, the paper proposes countermeasures to guide the maintenance and management of the production line.
