Cycle availability of a system. In the jargon of system maintenance,

“cycle availability” is defined as the probability that a system is functioning at any point in time. The U.S.

Department of Defense 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 10. Find the following parameters for cycle availability: mean, standard deviation, 20th percentile, lower quartile, and upper quartile. Interpret the results.
