SEMI-MARKOV APPROACH FOR DETERMINING THE RELIABILITY PARAMETERS OF COMPLEX SYSTEMS

Abstract

In the reliability investigation of complex systems it sometimes becomes necessary to deal with distributions of a general type. That mainly occurs in the case of system repair works. This problem may be solved by modelling the system with a semi-Markov model. In this paper, we derive closed-form expressions for the determination of reliability parameters, like availability and mean sojourn times. These results are the generalization of those given in the literature for the Markov case. This fact is shown in the paper, as well.
