Abstract
Reliability is a major issue for fault-tolerant systems used in critical applications. N-modular redundancy (NMR) is one of the traditional approaches used for fault masking in fault-tolerant systems. Reconfigurable NMR architecture supported with hot or cold standby spares is a common industrial method. So far, no systematic method for creating the Markov model of reconfigurable NMR systems supported with hot standby spares has been presented. Likewise, there is no explicit parametric formula for the reliability of these systems in the literature. This paper focuses on two issues: the systematic construction of the Markov model of reconfigurable NMR system, and its evaluation through a precise and explicit formula introduces in this paper. The introduced formula gives for system designer a good view of reliability behaviour of the reconfigurable NMR systems.
