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.
Analysis is done on how OEE has evolved leading to other tools like total
equipment effectiveness performance, production equipment effectiveness, overall
factory effectiveness, overall plant effectiveness, and overall asset effectiveness.
Two industrial examples of OEE application are discussed, and the differences
between theory and practice analyzed. Finally, a framework for classifying and
measuring production losses for overall production effectiveness is proposed.
The framework harmonizes the differences between theory and practice and
makes possible the presentation of overall production/asset effectiveness that can
be customized with the manufacturers needs to improve productivity
