Question

The term availability is used to indicate the probability of a system or equipment being in operating condition at any time t, given that it was in operating condition at:

• A. 1
• B. 0
• C. \(\alpha\)
• D. constant

Hint:

Availability is a critical metric in maintenance and reliability. To improve availability, focus on reducing downtime and increasing the reliability of equipment.

Answer 1

The Correct Option is C

Availability is a measure of the probability that a system or equipment is operational at any given time, considering that it was operational at some prior point. The symbol \(\alpha\) represents the probability that the equipment is still in working condition after a certain period, which accounts for both repair and downtime. In reliability and maintenance contexts, availability can be expressed as the ratio of the time the system is functional versus the total time. The parameter \(\alpha\) signifies this probabilistic measure.
