{"id":"oee","model_id":"OEE","name":"Overall Equipment Effectiveness","summary":"OEE measures how much of planned production time a machine spends making good parts at full speed. It multiplies three ratios: availability, performance and quality. A score of 1.0 means only good parts, as fast as possible, with no stops.","study_notes":["Availability = run time / planned production time.","Performance = (ideal cycle time x total count) / run time.","Quality = good count / total count.","The three factors multiply, so three 90% scores give an OEE of about 73%."],"safety_notes":[],"sources":[{"url":"https://www.oee.com/calculating-oee/","title":"OEE.com: Calculating OEE","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":4,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"operational","spec":{"kind":"metric","formula":{"expression":"OEE = A * P * Q","variables":[{"symbol":"A","name":"Availability","min":0,"max":1},{"symbol":"P","name":"Performance","min":0,"max":1},{"symbol":"Q","name":"Quality","min":0,"max":1}],"worked_example":{"inputs":{"A":0.9,"P":0.95,"Q":0.98},"output":0.8379}},"related":[]},"url":"https://machineschema.com/operational/oee","license":"https://creativecommons.org/licenses/by/4.0/"}
