Reliability and availability analysis of an n-unit outdoor power system subject to adjustable repair facility

Abstract This paper presents a newly developed stochastic mathematical model to represent a system of n active redundant outdoor power equipment. The system considered is subject to common cause failure and adjustable repair facility. Laplace transforms of the state probabilities, system reliability and availability equations are developed. In addition, steady-state availability and mean-time-between-failures expressions are developed. The special case when n = 2 is discussed numerically.
