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

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
