Evaluation of some reliability parameters of a three state repairable system with environmental failure. (English) Zbl 1180.90088

Summary: This paper deals with a 3-state repairable complex system with three types of failure. In this paper a mathematical model has been developed for exponential failure and general repairs. Various states probabilities have been evaluated in the form of Laplace Transform. Expression for various Reliability parameters of the system are obtained by the inversion process and then computations are done for M.T.S.F. (Mean time to system failure) and Reliability of the system. All necessary graphical illustrations are given at the end so as to explain the practical utility of the model.
