It provides a systematic method for establishing production targets, and incorporates practical management tools and techniques in order to achieve a balanced view of process availability, performance efficiency and rate of quality .As stated earlier that an overall 85 percent benchmark OEE is considered as world-class performance.
However, it is desirable to find the gaps between the existing performance levels and desired performance levels. Calculating the OEE following mathematical models (Sohal et.al. 2010) is adopted. The high level of effectiveness OEE will be achieved only, when all the three indexes are very high.
