The paper presents a reliability analysis of rodding anode plant in aluminum industry. Manufacturing process of raw aluminum passes through eight stations viz., butt shot blast station 1, butt & thimble removal press station 2 with standby arrangement, combined btp (butt & thimble press) station 3, stub straighten station 4, stub shot blast station 5, stub coating and drying station 6, casting station 7, and anode rod inspection station 8. Failure of any of the stations brings the system to a complete halt, except the butt & thimble removal press stations because of the parallel standby arrangement, and does not affect the system operation completely unless both fails. Six years maintenance data on component failures, repairs and associated costs are collected for the purpose of this analysis and various rates are estimated from the data. Measures of system effectiveness such as mean time to plant failure (MTPF), availability of the plant, busy period of repairman and expected number of repair have been obtained. Semi-Markov processes and regenerative point techniques are used in the analysis.
