The simplest way to calculate OEE is as the ratio of Fully Productive Time to Planned Production Time. Fully Productive Time is just another way of saying manufacturing only Good Parts as fast as possible (Ideal Cycle Time) with no Stop Time. Hence the calculation is OEE = (Good Count Ideal Cycle Time) / Planned Production Time

Frequently when drawing a best-fit regression line through the data points on a Weibull plot the coefficient of correlation is poor meaning the actual data points stray a great distance from regression line. This is assessed by examining the coefficient of correlation R or more conservatively R2 which denotes data variability.
