Abstract

Overall Equipment Effectiveness (OEE) is the product of availability, performance and quality multiply together, which are looking for the losses such as downtime losses, speed losses and quality losses respectively. This study is carried out in an aero-composite company to acquire the time data of the Autoclave section via the computerized recording system. Miscalculation of OEE for not including details of all the operational factors that involved in the operation, further causing inaccurate OEE data. In this study, a framework is developed to determine the operational factors specifically. The framework is used to calculate the OEE rate, which helps to identify the 16 losses correctly in the company for the duration of 59 days. As a result, the utilization of this framework is managed to surpass 85% OEE, which the company aimed for best practice. By specifically including the operational factors in the calculation, the OEE rate resulted in this study is 85.40%, which is comparable to the value of OEE determined by the company at a 69.65% rate. Furthermore, the framework can be used by many other companies to accurately calculate the OEE rate. This study is focused on the utilization of the framework to achieve an improvement in OEE rate by including operational factors in OEE calculations.
