“…It is therefore, essential to keep the plant in continuous operation without any trouble. Reliability models and its analysis for different types of industrial systems have been widely discussed under various assumptions and operating conditions by number of researchers [2][3][4][5][6][7][8][9]. Recently, Rizwan et al [1] extended the modeling methodology to a single unit PLC controlled system and the related reliability indices along with profit incurred to the system are obtained.…”

“…Probabilistic analysis using modeling approach plays an important role in understanding the system behaviour in terms of reliability indices and cost benefit evaluation. Gulshan et al [1] analyzed system with perfect repair under partial failure mode and priority for repair to completely failed unit, Gopalan & Bhanu [2] considered two unit repairable system subject to online preventive maintenance and/or repair, Tuteja et al [3]- [5] worked for two units system with regular repairman who is not always available, system with perfect repair at partial failure or complete failure mode, and the profit evaluation of a two units cold standby system with tiredness and two types of repairmen. Rizwan et al [6]- [12] analyzed cold and hot standby systems with single unit and two units under different failure and repair situations where the reliability indices of interest are obtained and the cost benefit analysis of the systems are carried out.…”

The paper presents probabilistic modeling and analysis of a cable plant subsystem with two identical machines operating in parallel. Seven years failure data of the cable plant depicts three types of maintenances for the subsystem: repair, minor preventive maintenance and major preventive maintenance. The subsystem undergoes repair upon failure while minor and major preventive maintenance is performed as per schedule. Priority is given to repair over preventive maintenance. Mean time to failure, availability, expected busy period and expected number of repairs have been estimated by analyzing the subsystem using semi Markov process and regenerative point technique. Graphs have been established to demonstrate simulated results.

“…Goel and Murari (1990) discussed two-unit cold standby redundant system subject to random checking, corrective maintenance and system replacement with repairable and non-repairable types of failure. Gopalan and Bhanu (1995) studied two unit repairable system subject to on-line preventive maintenance and/or repair. Gupta et al (1997) analysed a system having super-priority, priority and ordinary units with arbitrary distributions.…”

In the present paper, a stochastic model for the system involved in the printed circuit boards(PCBs) manufacturing process is developed. The manufacturing process, based on Surface Mount Technology (SMT), is carried out in three stages viz. printing, placing and soldering through a hardware-software system. During the process, inspections, maintenances and repairs on occurrence of faults of the system are done by internal/external engineers. The internal engineers inspect the system and every manufactured PCB. The system's software faults as well as faults in the PCBs are repaired by the internal engineers whereas system's hardware faults are repaired only by the external engineers. In the model, possibilities of different kinds of faults, online PCB's repairs and arbitrary arrival time of the external engineers, are also incorporated. The expressions for various measures of system performance have been derived using Markov process and regenerative techniques. In the last, numerical computation and graphical analysis have been given for a particular case to show the effect of various parameters on the system performance and cost-benefit.
