Abstract

Overall Equipment Effectiveness (OEE) is a commonly applied metric for assessing productivity in industrial operations. This study analyzes its practical application through a stepwise implementation based on production data obtained from an active manufacturing line. In situations where complete operational records were not available, supplementary data were constructed using realistic assumptions consistent with observed operating conditions. The analysis emphasizes losses associated with equipment availability, operating performance, and product quality, which are frequently underestimated in conventional production monitoring. Recorded operational data were used to characterize these losses and to evaluate their distribution throughout the production process. Based on the observed results, improvement actions related to downtime registration, basic preventive maintenance practices, and rapid changeover techniques, such as SMED, were examined within the evaluated context. The findings indicate that variations in unproductive time have a measurable impact on OEE values, demonstrating that performance improvements can be achieved without immediate investment in additional equipment. The results are representative of manufacturing environments operating under technical and resource-related limitations.

Keywords
