Overall Equipment Effectiveness (OEE) is a commonly used indicator in manufacturing plants. It allows to determine how efficient is a given production line, and thus how efficient the production is in relation to its production capabilities. The index is the result of three factors to measure the performance of a production line:
Availability = actual machine running time / scheduled time
Productivity (actual production time / production capacity)
Qualitร (number of pieces properly produced / total production)
Nell'industria manifatturiera, l'enfasi รจ posta sul raggiungimento di prestazioni ottimali in tutte e tre le aree, che sono fondamentali per il successo del funzionamento della linea, poichรฉ ogni area contribuisce singolarmente alla redditivitร di un prodotto o di un servizio e alla redditivitร .
OEE puรฒ anche essere rappresentato come la produzione effettiva divisa al denominatore in tempo programmato moltiplicato per un ciclo di produzione, come mostrato nella formula seguente:
Ultimately, OEE is influenced by many factors that depend on the overall operation of the factory. Among the events that have an impact are
- Unplanned downtime
- Failures and repair times MTTR, MTBR, MTTF
- Slow start-up of production
- Late recognition that a process is unstable
