ProAlert · OEE Sandbox

Typical Shift

A shift is made of runs. Each run carries its own OEE; the shift totals the parts rather than averaging the percentages, so a twelve-minute trial lot cannot swing the day the way a four-hour run does. World class is 94% availability, 92% performance and 98% quality — 85% OEE. Anything under target reads red below.

Target rate and units per cycle are master data per product. Cycles are counted at the machine; units follow. Units per cycle cancels out, so Performance is a cycle-rate comparison.

Simple average of the runs—
World class is A 94% × P 92% × Q 98%, which multiplies out to 85% OEE.
