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.
