5. Conclusion: In present study, reliability analysis and availability prediction of the stock preparation unit in a paper manufacturing plant has been conducted and along with RAMD investigation of all its subsystems. It is observed that system reliability is highly influenced by time and failure rates of subsystems. The subsystem deflaking is the most sensitive and highly influence the performance of the system. It is recommended to operate it with utmost care to enhance the reliability of the whole system. Based on maintainability measures, it is recommended to plan maintenance strategies. The steady state availability of the stock preparation unit is sharply decline with the increase of failure rates and increase with the increase of repair rates. Nature inspired algorithms predict that optimal availability is 0.9207 at a population size of 2500 after 80 iterations using GA that is much higher than the maximum value 0.8947 predicted by PSO at population size of 1000 after 60 iterations. It is observed that GA outperformed PSO in the availability prediction of stock preparation unit. The present investigation performed under various assumptions that can be treated as the limitations of the study and in further work it can be extended. The same methodology may be applied in production industries of same kind. Finally, it is concluded that to enhance the performance of stock preparation unit of paper plant special attention should be given to deflaking unit by adopting proper maintenance and redundancy strategies. The system designers may use estimated parameters values to design highly reliable systems.
