Abstract: This paper is concerned with modeling and sensitivity analysis of a urea fertilizer making system consisting of a number of subsystems of varying nature. Taking constant failure and general repair rates for each subsystem, the system is analyzed by using Regenerative Point Graphical Technique (RPGT). A common cause failure is also considered in modeling. A state diagram of the system depicting the transition rates is drawn expression for path probabilities mean sojourn times, mean time to system failure, availability of the system, busy period of the server, expected number of server’s visits are derived using RPGT, which are useful to system managers, engineers, training supervisors and reliability analysts are obtained. Particular cases and sensitivity analysis w. r. t. various rates are also carried out follow by graphs and conclusion.
