Automatic OEE Calculation: From Equipment Signals to Efficiency Metrics
OEE = availability × performance × quality. SBK MES auto-recognizes status from equipment signals, computes quality from reporting data, and derives performance from output cycle times, giving a real OEE rather than an estimate.
- Availability: (planned time − downtime) / planned time
- Performance: (actual output × standard cycle) / running time
- Quality: good output / total output
- Downtime classification: planned stop / fault / changeover / material shortage / waiting for personnel
