Stochastic Availability of a Repairable System with an Age - and Maintenance - Dependent Failure Rate,

Abstract

A general repairable system model is proposed with a maintenance schedule such that the failure rate is reduced after each preventive maintenance. The model introduces naturally the concept of system availabilities as random variables. Probability distributions of the stochastic availabilities are derived. The stochastic availability is optimized with respect to the duration of the operating interval between maintenance operations, and with respect to an age replacement policy. Analysis and optimization are achieved by a PASCAL computer program which is developed for computations and illustrations of various failure rate characteristics and parameter variations. The concept is further extended to stochastic cost function or generalized stochastic availability. (Author)
