Dependability analysis of paper mill plant under multi-state repairable systems execution.

Paper has been in common use for centuries and plays an important part in our daily life. The paper making process is a complex process that comprises various steps. Thus, a component's breakdown or failure can lead to poor system performance or in system failure. Therefore, a comprehensive system analysis is necessary for improved performance. In this research, the authors have examined the operation and performance of a paper mill, in order to gauge and enhance its performance. The reliability, availability, maintainability and dependability (RAMD) of the system are analysed. Appropriate mathematical models are developed on the basis of Markov birth-death processes to analyse production under steady-state conditions. The whole system is made up of six subsystems. Measures of the reliability, availability, maintainability, dependability, mean time between failures (MTBF), mean time to failure (MTTF), and dependability ratio are evaluated for the entire system.
