In this modern society, systems are complex enough and are designed to be operative for a specified period. This specified period is called the mission time. Our aim is to get improvement in this mission time. Availability analysis of each unit of equipment under given operating conditions is helpful to design the units for a minimum failure and to develop a plan in advance for scheduled maintenance or preventive maintenance. the authors have considered in this paper, a multi - component redundant complex system for evaluation of various reliability parameters. Supplementary variable technique and Laplace transform have used to formulate and solve the mathematical model. Laplace transform of various state probabilities, reliability, availability and M.T.T.F. of the system have obtained. Some particular cases and steady-state behaviour of the system are also given at the end. A numerical example with graphical illustration has also been mentioned in last to highlight the important results. We may utilize this general approach to the similar systems used in any industry or elsewhere.
