【摘要】：在市场竞争激烈的今天,物料成本已经很透明,企业要想在市场激烈的竞争中脱颖而出,就要最大化的挖掘自身生产效率和降低制造成本。针对这种现象,TPM组织提出了设备综合效率(OEE)的管理理论。设备综合效率是衡量企业生产效率的指标,通过对设备综合效率的改善可以直观的看出企业的生产效率变化情况,容易找出瓶颈设备,为改善活动提供了良好的切入点。本文针对A公司118F-C生产线设备综合效率不高的问题进行改善活动,主要运用了鱼骨图、因子分析方法找出影响A公司118F-C生产线设备综合效率的主要因素,并建立预防维修间隔期与生产总收益之间的关系模型,以确定合理的预防维修间隔期,然后用快速换模、平行顺序移动加工方式和控制图等方法对设备综合效率的三大指标时间开动率、性能开动率、良品率进行改善,降低了由外部因素造成的时间损失、计划维修造成的时间损失以及改装换线造成的损失,最后通过改善方案的实施和跟踪,使得改善对象A公司118F-C生产线上瓶颈设备的设备综合效率提高到88.6%,提升了生产线的生产效率,为公司带来了直接的经济收益。通过用设备综合效率对A公司生产设备进行改善,以及改善的结果可以表明,设备综合效率理论对国内制造型企业提高设备综合利用水平具有一定的借鉴意义。
[Abstract]:In the fierce competition in the market today, material costs have been very transparent, enterprises want to stand out in the fierce market competition, we must maximize the mining of their own production efficiency and reduce manufacturing costs. TPM has put forward the management theory of equipment comprehensive efficiency (OEE), which is an index to measure the production efficiency of enterprises. Through the improvement of the comprehensive efficiency of the equipment, we can intuitively see the change of the production efficiency of the enterprise, easy to find out the bottleneck equipment. For improving the activities to provide a good entry point. This paper aimed at A company 118F-C production line equipment comprehensive efficiency is not high improvement activities, mainly using the fish bone map. Factor analysis method was used to find out the main factors that affect the comprehensive efficiency of 118F-C production line of A Company, and the relationship model between preventive maintenance interval and total production income was established. In order to determine a reasonable preventive maintenance interval period, and then use the methods of rapid mold change, parallel sequential moving processing and control chart to the equipment comprehensive efficiency of the three indicators of the time start rate, performance start rate. The rate of good products is improved to reduce the time loss caused by external factors, the time loss caused by planned maintenance and the loss caused by the modification and replacement line. Finally, the implementation and tracking of the improved program are improved. So that the comprehensive efficiency of the bottleneck equipment on the 118F-C production line is increased to 88.6, and the production efficiency of the production line is improved. It brings direct economic benefits to the company. By using the equipment comprehensive efficiency to improve the production equipment of company A, and the result of the improvement can be shown. The theory of equipment comprehensive efficiency has certain reference significance for domestic manufacturing enterprises to improve the level of comprehensive utilization of equipment.
