OEE Metrics Calculations

...

Examples

• Example 1: All grey period (idle status)

• Example 2: Mixed uptime and downtime periods

• Example 3: Production without Jobs

• Example 4: Production with complicated machine status

• Example 5: Special case with a small error

OEE Metrics Calculations

• OEE = Availability * Performance * Quality

  • Availability = Uptime / Planned Productive Time

  • Performance = (Number of parts produced) / (Machine rate * Uptime)

  • Quality = [(Number of parts produced) - (Number of parts rejected)] / (Number of parts produced)

• OEE = Availability * Performance * Quality Ratio

• OEE = Good Production (pcs) / ( Expected speed (parts/hr) * Scheduled Time (hr) )
