摘要

本研究的目的是基于整体设备有效性(OEE)计算来确定K-440拖运卡车的有效性,并基于鱼骨图和故障模式与影响分析(FMEA)找出导致K-440拖运输卡车无效的主要因素,并分析了为克服K-440拖运卡车的主要问题而提出的适当改进的实施方案。所使用的方法是混合方法,研究类型是描述性的。使用的分析方法有OEE、鱼骨图和FMEA。结果表明,三辆K-440拖运卡车的平均有效性仍远低于国际标准,为44,99%。根据鱼骨图分析,材料是导致低OEE的重要因素。根据FMEA分析的风险优先数(RPN)临界值,有五个问题,即变速器工作不正常、制动衬片磨损、传动轴在轴上未旋转、制动鼓破裂和弹簧断裂。针对K-440型载重汽车的主要问题,提出了全面生产性维修的八大支柱的实施方案。基于这些结果,公司需要实施TPM的八大支柱,并定期进行OEE计算。

The Measurement and Improvement of Effectiveness in K-440 Haul Truck Using Overall Equipment Effectiveness in Coal Mining Company
The objectives of this study were to determine the effectiveness of K-440 haul trucks based on Overall Equipment Effectiveness (OEE) calculation, to find out the main factors that caused the ineffectiveness of K-440 haul trucks based on fishbone diagram and Failure Mode and Effect Analysis (FMEA), and to analyze the proposed implementation of appropriate improvements to overcome the main problems of K-440 haul trucks. The method used was the mixed method, and the type of research was descriptive. The analysis methods used were OEE, fishbone diagram, and FMEA. The results show that the average effectiveness of the three K-440haul trucks is still far below international standards, which is 44,99%. The material is a significant factor that causes low OEE based on fishbone diagram analysis. There are five problems based on the Risk Priority Number (RPN) critical value from FMEA analysis, namely transmission which is not functioning properly, worn brake lining, unrotated propeller shaft on the shaft, cracked brake drum, and broken spring. Then, the implementation of eight pillars of Total Productive Maintenance (TPM) is proposed in overcoming the main problem of K-440haul trucks. Based on these results, the company needs to implement eight pillars of TPM and carry out OEE calculations regularly.
