This paper develops a mathematical model of a complex bubble gum production system with an attempt to improve its availability. The methodology for determining the availability of the system is based on Markov Modeling. The mathematical model is established using probability considerations and supplementary variable technique. Lagrange’s method for partial differential equations is utilized to obtain the state probabilities. The reliability characteristics are evaluated and analyzed in accordance with practical situation and operational behavior of the system.  Availability analysis of the system has helped in identifying the critical factors and assessing their impact on the system availability. I is possible to achieve an improvement in system availability by 3.27 per cent.
