Enhancing Overall Equipment Effectiveness (OEE) of a Selected Machine in a Light Manufacturing Factory in Bangladesh

Abstract

Overall equipment effectiveness provides reliable and considerable performance indicators for machinery performance. This research aimed to measure the OEE of the selected machine, identify the reasons behind its poor performance, and take action to improve the machine's overall performance. A tire-curing machine was chosen for the research as the target machine for OEE analysis. After collecting data for a month, we did our calculation using Microsoft Excel and found OEE of just 63%, which is far below the industry standards. We investigated the causes of the low OEE and found that most affected the availability and performance metrics while quality was good. For the following month, several performance improvement activities were taken including maintenance improvements, process optimizations, and operator training. The new data collection and analysis phase was carried out after the implementation phase to measure the impact results of the interventions. The OEE of the machine improved from 63% to 73%, showcasing a significant increase in efficiency; that is, availability increased by 79% to 85%, while performance improved from 82% to 88%. This research also highlights the importance of OEE as it gives a comprehensive view of how machines and equipment may be tracked and improved.
