The present paper stochastically analyze a system comprising two dissimilar units (unit-1/unit-2) working in series configuration. System fails completely when either of the units gets failed. The repair time of unit-2 is considered to be much more as compared to the repair time of unit-1. So, to minimize the breakdown period of the system, a standby unit is provided against the second unit. Regenerative point technique (RPT) is used to develop a semi-markovian reliability model for the mentioned system. Optimum cut-off points concerning the profitability of the system have also been obtained. The model has applications in industries, particularly in aluminum industry.

“…Performance analysis of various complex industrial systems operating under different conditions and assumptions has been widely discussed by a number of researchers [31][32][33][34][35][36][37]. Recently, Taj et al [27][28][29][30] carried out performance analysis of four different subsystems of a cable plant.…”

The paper presents performance analysis of a rod breakdown system consisting of two machines operating in parallel. Ten years maintenance data of the system depicts three maintenance practices: repair, major preventive maintenance and minor preventive maintenance. Machines are repaired on normal failures, whereas major/minor preventive maintenance is carried out at scheduled basis. The machines are queued for major preventive maintenance. An operative machine requires a cooling period of half hour before undergoing major preventive maintenance. Repair is prioritized over major preventive maintenance. The system is analysed using semi-Markov processes and regenerative point techniques. Performance indices namely mean time to system failure, system availability, no. of system repairs and busy period of the repairman are obtained. Simulated results are presented to demonstrate the effect of varying failure/repair rates on the system performance.

“…Thus, the methodology for industrial system analysis has been widely presented in the literature and proved to be a good tool for industrial system analysis, and therefore the novelty of this work lies in its case study for a different system with different operating conditions. Recently, the methodology was further extended by Yaqoob Al Rahbi et al (2017) for analyzing a system of rodding anode plant in Aluminum industry. Aluminum manufacturing process 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.…”

The paper presents reliability analysis of a rodding anode plant in aluminum industry with multiple unit failure and single repairman. Manufacturing process of raw aluminum blocks in this plant passes through eight stations viz., butt shot blast station 1 with three components, butt & thimble removal press station 2 with standby arrangement, and here each machine consists of two components, combined btp (butt & thimble press) station 3 with one component, stub straighten station 4 with one component, stub shot blast station 5 with two components, stub coating and drying station 6 with two components, casting station 7 with four components, and anode rod inspection station 8 with one component. 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 the units fail. Six years of maintenance data on component failures, repairs and associated costs are used in this analysis. Measures of system effectiveness is gauged through reliability indices such as mean time to plant failure (MTPF), availability of the plant, busy period of repairman and 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 and regenerative stochastic processes is used in the analysis.
