STOCHASTIC-ANALYSIS OF A REPAIRABLE SYSTEM WITH 3 UNITS AND 2 REPAIR FACILITIES

This paper investigates the availability characteristics and the relia bility of a three-dissimilar-unit repairable system with two different repair facilities. Under some practical assumptions, we obtain the ex plicit expressions of the state probabilities of the system and then t he explicit expressions of the following performance measures of the s ystem: (1) the pointwise and steady-state availability; (2) the pointw ise and steady-state failure frequency, (3) the pointwise and steady-s tate renewal frequency; and (4) the reliability and the mean time to s ystem failure.
