Abstract

The paper presents reliability analysis of a roddinganode plant in aluminum industry with multiple unitfailure and single repairman. Manufacturing process of rawaluminum blocks in this plant passes through eight stations.Failure of any of the stations brings the plant to a completehalt, except the butt & thimble removal press stationsbecause of the parallel standby arrangement, and does notaffect the system operation completely unless both theunits fail. Six years of real maintenance data on componentfailures, repairs and associated costs are used in thisanalysis. Measures of system effectiveness is gaugedthrough reliability indices such as mean time to plantfailure, availability of the plant, busy period of repairmanand expected number of repairs. Effect of repair rate,failure rate and repair cost on system performance w.r.t.revenue is shown graphically. Theory of Semi-Markov andregenerative stochastic processes is used in the analysis.
