Abstract

The quest for improving productivity in the current global competitive environment has led to a need for rigorously defined performance-measurement systems for manufacturing processes. In this paper, overall equipment effectiveness (OEE) is described as one such performance-measurement tool that measures different types of production losses and indicates areas of process improvement (Availability, Performance and Quality). Overall equipment effectiveness (OEE) is a well-accepted measure of performance in industry. This study investigates the analysis of machine failure, imbalanced posts and non-conforming products and was carried out over a period of 4 months. In fact, we have balanced the assembly line, increased the availability of the bottleneck by using the AMDEC-equipment tool, and proposed action plans to reduce the defect ratio. These improvements enabled us to increase the production by 29 wire/ shift, increase the time of production of the bottleneck to 7.83h/week, reduce the defect ratio and standardize the processes. Finally, and thanks to the established improvement, we have increased the efficiency of our new line by 37.2% giving it thus an efficiency of about 76.2% exceeding the 63% fixed by the company.
