Reliability Modelling And Analysis Of Complex Industrial Systems - A Review

Source abstract

The twenty first century is a century of technology. We are living in a world where technological advancement has become a daily affair. Such fast enhancement of technology has resulted in the increased costs and complexity of the present day's industrial systems. Thus, it is crucial to operate these systems with reduced downtime, in order to attain optimized production and profit, and to evade the losses. Hence, the need for reliability modeling and analysis of complex industrial systems is inevitable. Many researchers have contributed to the field of reliability modeling whilst analyzing complex industrial systems under different operating conditions and assumptions. Davis (1952) had discussed failure data and goodness of fit tests considering various failure distributions. Epstein and Sobel (1955) have worked in the field of life testing with the assumption of exponential distribution. Gaver (1963) was the first to generalize repair time distribution and use supplementary variable technique to analyze the model. The concept of availability has been widely discussed in the literature (Sandler, 1963; Barlow & Proschan, 1965) . Srinivasan and Gopalan (1973) concentrated on regenerative point techniques. Ramanarayanan and Usha (1979) analyzed n-unit warm stand by system using Erlang distribution. Kumar and Agarwal (1980) have presented a review of standby redundant systems. Usha and Ramanarayanan (1980) extended their previous work for the analysis of two n-unit cold stand by systems using Erlang distribution. Afterwards, Yasmashiro (1982) used supplementary variable technique to analyze a repairable system with n failure modes and k standby units. Gopalan and Naidu (1983) analyzed a one-server two-unit system subject to nonnegligible inspection time for busy period. Rastogi, Kumar, and Goel (1983) have studied the effect of intermittent repair in a two unit redundant system with standby failure. Murari, Goyal, and Rani (1985) carried out cost analysis in two-unit warm standby models with a regular repairman and patience time. Yearout, Reddy, and Grosh (1986) also presented a review of standby redundancy in reliability. Goel and Sharma (1989) estimated reliability and availability of a 2-unit standby system with two failure modes and slow switch, using regenerative point techniques. Further, Goel and Shrivastava (1991) focused on two-unit redundant system with provision for rest and correlated failures and repairs. Gupta and Bansal (1991) calculated the profit of a two-unit cold priority standby system subject to degradation, whereas, the profit of a two unit-cold standby RELIABILITY
