Availability of an asset is a function of which two metrics?

  1. Cost and downtime

  2. Uptime and downtime

  3. Performance and maintenance

  4. Design and operation

The correct answer is: Uptime and downtime

Availability of an asset is fundamentally defined as the ratio of the time an asset is operational and can perform its required function (uptime) to the total time the asset is expected to be operational, which includes both uptime and downtime. This relationship can be mathematically expressed as: Availability = Uptime / (Uptime + Downtime) Uptime refers to the time during which the asset is functioning correctly and is ready to produce or fulfill its purpose, while downtime is the time during which the asset is not operational due to repairs, maintenance, or other issues. Therefore, both uptime and downtime are critical metrics in understanding and measuring availability. This concept is central to maintenance and reliability practices, as improving uptime while effectively managing downtime will lead to better asset availability and reliability outcomes. Although the other choices mention various factors that can impact asset performance and costs, they do not directly measure availability in the way that uptime and downtime do. For example, performance relates to how well an asset operates when it is available, while maintenance refers to activities conducted to ensure that an asset remains in good condition but does not measure the specific availability metric itself.
