STOCHASTIC ANALYSIS OF A DISCRETE PARAMETRIC MARKOV CHAIN MODEL OF A COMPLEX SYSTEM CONSISTING OF TWO SUB-SYSTEMS
The paper deals with a stochastic model of a complex system composed of two subsystems- A and B. The subsystem-A consists of two identical units in series configuration whereas subsystem-B consists of only a single unit and is capable to keep the system operative when subsystem-A is failed. System failure occurs only when at least one unit of subsystem-A together with subsystem-B is failed. A single repairman is always available with the system to repair a failed unit of subsystem-A and B. Priority in operation as well as in repair is given to the unit of subsystem-A.
