Question: In a 480 minute shift: On a machine rated at 100 products output per minute Maximum output = 480 mins x 100 units = 48000

In a 480 minute shift: On a machine rated at 100
In a 480 minute shift: On a machine rated at 100 products output per minute Maximum output = 480 mins x 100 units = 48000 units Shift info: Output (Good Production) = 32000 units Speed =98 units per minute Planned downtime = 82 mins Bottleneck loss due to B down = 30 mins Rejects (in process) = 1255 in 8 hr shift Output (OEE) - 32000 / 48000 = 66.7% 480mins x 66.67% = 320 mins, therefore Total Loss = 160 mins Six Loss Calculations: Speed loss Max theoretical units possible at actual speed = 98 x 480 = 47040 = (32000/47040) - (32000/48000) = 68.03% - 66.67% = 1.36% 480 x 1.36% = 6.53 mins / 480 = (1.36%) Planned downtime = 82 mins / 480 = (17.08%) Breakdown = 30 mins / 480 = (6.25%) Rejects - 1255 / 98 (actual running speed) = 12.81 mins / 480 = (2.67%) Minor stops = 480-320-6.53-82-30-12.81 = 28.66 mins / 480 =(5.97%) Total loss = 160 mins = (33.33%) OEE Calculations (Time in mins): Production time = 480 Time less availability loss = 368 Time less performance loss = 333 Availability Loss Performance Loss Quality Loss Planned downtime =82 Speed loss -6.53 Rejects on start up Breakdowns =30 Minor stops (
