Overall Equipment Effectiveness (OEE) and Overall Plant Efficiency (OPE)

Overall Plant Effectiveness (OPE) is the ratio in percentage of
Actual Accepted Quantity Produced (Q2) to the Quantity that should have been produced in Total Scheduled Hours (T2xN)
That is, OPE = {Q2/T2xN}x100%
And, similarly,
Overall Equipment Effectiveness (OEE)
Is the ratio in percentage of
Actual accepted quantity produced (Q2) to the Quantity that should have been produced in Total Loading Hours (T3xN)
That is, OEE = {Q2/T3xN} x100%
(Where N is the 100% Rated Output per Hour)

Overall Equipment Effectiveness (OEE)
Can also be expressed as
OEE = Availability x Performance Rate x Quality Rate
Where,
Availability is the ratio in percentage of
Total Operating Hours (T4) to Total Loading Hours (T3)
Performance Rate is the ratio in percentage of Actual Quantity Produced (Q1) to Quantity that should have been produce in Total Operating Hours (T4)
Quality Rate is the ratio in percentage of
Actual Accepted Quantity Produced (Q2) to Actual Quantity Produced (Q1)

Thank you for sharing the information.

In any manufacturing industry the process of producing goods or services on time is very important and to achieve this purpose various types of system are being used to increase the production process.

Now a days, there are number of companies who are providing the service of MES and OEE and while surfing on internet, I came across a site named as Redzone who is providing the service of MES & OEE system which is a process of producing the goods to get high return on investment.
