WebAug 2, 2013 · As a result the line yielded 150 minutes of perfect running at quality and at rate. Theoretically we could make 480 x 60 = 28,800 bottles. At the end there were 9,000 bottles that were saleable, so the Overall Equipment Effectiveness was 31.25%. 9,000 ÷28,800 = 31.25% OEE. Availability (62.5%) x Performance (66.7%) x Quality (75%) = 31.25%.
