Software Rejuvenation Policies for Cluster System

摘要

abstract_textpThis investigation deals with the reliability analysis of an embedded cluster system by incorporating the concept of software ageing which is the significant cause of fault occurrence in the system. To develop the Markov model, we consider four levels of software rejuvenation policies. The system state probabilities are evaluated which are further used to derive various indices such as the availability, mean time to failure, down time cost, etc. To validate the computational tractability of different formulae established, a numerical illustration has been provided. The sensitivity of reliability indices with respect to different parameters has also been examined./p/abstract_text
