In the present work, time dependent availability of sole lasting unit in a shoe making plant is estimated. Here, simulation and modelling has been developed on the basis of Markov birth-death process using probabilistic approach. The first order governing equations thus formulated using the mnemonic rule are solved to estimate the availability of the system. The failure rates and the repair rates of the subsystems are taken constant and are statistically independent .The solution of these equations is carried out using more sensitive and advance numerical technique, known as adaptive step-size control Runge-Kutta method to find the time reliant availability. This performance model deals with quantitative study of all aspects which influence all maintenance decisions associated with sole lasting unit system. The results obtained in the present work are considered to be very useful for devising the best possible maintenance strategies.
