Analysis of performance by overall equipment efficiency : case study

Metrics for measuring and analyzing the productivity of manufacturing facilities have been studied for several decades. Consequently, it is discovered that measurement is needed for identifying the problems in order to improve and increase productivity. To achieve this, it is necessary to establish appropriate metrics for measurement purposes. In an ideal situation a process would produce 100 % of the time at 100 % capacity with an output of 100 % good quality. The difference between the ideal situation and the actual is due to different kinds of losses.
