# Cycle availability of a system.

**Question description**

Cycle availability of a system. In the jargon of system maintenance, *cycle availability *is
defined as the probability that the system is functioning at any point
in time. The DOD developed a series of performance measures for
assessing system cycle availability (START, Vol. 11, 2004). Under
certain assumptions about the failure time and maintenance time of a
system, cycle availability is shown to be uniformly distributed between 0
and 1. Find the following parameters for cycle

availability: mean, standard deviation, 10th percentile, lower quartile, and upper quartile. Interpret the results.
