RELIABILITY ANALYSIS OF A TWO UNIT COLD STANDBY SYSTEM USING MARKOV PROCESS

Abstract

This paper deals with the reliability analysis of a system having four components arranged in series. Subsystems A, B, C have single unit whereas subsystem D has three units where one unit is active and the other two are cold standby arranged in parallel. System can completely fail either due to the failure of subsystems A, B and C or due the failure of all units of subsystem D. All failure rates are constant and all repair rates follow the general time distribution. The analysis is carried out using the supplementary variable technique and Laplace transformation for evaluating the reliability measures.
