Standardizing Availability Definition - Plant Maintenance

A goal of availability-based maintenance operations is to find the peak of the curve and operate at that level. It is crucial to know the location and shape of the achieved availability curve. Otherwise, it is not possible to determine what is reasonable and possible for operational availability and, therefore, plant production. If the Aa curve is

One Point Lesson: Operational Availability vs. Rate of ...

Aug 31, 2006 Operational Availability = Time equipment actually able to run / Time when equipment is needed to run. If the equipment was down 2 hours out of a 20 hour period when the equipment was needed (available only 18 hours), the Operational Availability would be 18 hours / 20 hours = 9/10 = 0.9 = 90%. What is Rate of Operation

Calculate OEE – Definitions, Formulas, and Examples OEE
