Overall Equipment Effectiveness

Definition

Quality Index: Share of good sheets of all printed sheets in percent
Total of all good sheets / Total of all printed sheets
Speed Index: Utilization of maximum printing speed in percent
Average Press Speed / Maximum Press Speed
Time Index 1: Share of printing within operation time
Total Printing Time / Total Operation Time
Time Index 2: Share of printing within operation time
Total Printing Time / Total Available Time
OEE 1: Quality Index x Speed Index x Time Index 1
OEE 2: Quality Index x Speed Index x Time Index 2

 

Example of OEE calculation based on one job

Sample Job: 15,000 good sheets
Waste Allowance 800 Sheets (2% run waste = 300 sheets, 500 make ready sheets)
Average Speed 12,500 impressions / hour
Press to run available time 2 hours
Quality Index: 15,000 good sheets / 15,800 total sheets
Index Calculation Index-Value
Quality Index 15,000 good sheets / 15,800 total sheets 94.90%
Speed Index 12,500 / 15,000 impressions per hour 83.30%
Time Index 1.2 hours printing + 0.5 hours make ready = 1.7 hours
1.7 h/ 2h
85.00%
OEE 94.9% x 83.3% x 85.0% 67.00%
