PROFIT ANALYSIS OF A COMPLEX SYSTEM WITH CORRELATION IN TIME TO PREVENTIVE MAINTENANCE AND TIME TAKEN IN PREVENTIVE MAINTENANCE
This paper deals with the cost benefit analysis of a complex system with correlation in time to preventive maintenance and time taken in preventive maintenance. The system consists of two subsystems, say A & B, connected in series. Subsystem A consists of two identical units while subsystem B consist only one unit. The operation of only one unit of subsystem A with subsystem B is sufficient to do the job. The joint distribution of time to preventive maintenance and time taken in preventive maintenance are taken bivariate exponential. Each repaired unit works as good as new. Various measures of system effectiveness of interest to system designers and operation managers are obtained by using regenerative point technique. The graphical behaviors of MTSF and profit function have also been studied.
