RELIABILITY AND PROFIT ANALYSIS OF A TWO-UNIT COLD STANDBY CENTRIFUGE SYSTEM CONSIDERING REPAIR AND REPLACEMENT WITH INSPECTION

摘要

This paper deals with a centrifuge system consisting two identical units considering major/minor fault. It is assumed that system leads to partial failure state on occurrence of a minor fault whereas on occurrence of a major fault it leads to complete failure. On complete failure of the system, the repairman first inspect whether the fault is repairable or non repairable and accordingly carry out the repair or replacement of the components involved. Various measures of system effectiveness are obtained by using Markov processes and regenerative point technique. The analysis of the system is carried out on the basis of the graphical studies and conclusions are drawn regarding the reliability of the system.
