Abstract

In recent years, remarkable attention has been focused on software aging phenomena, in which the performance of software systems degrades with time. Fault-tolerant software systems which provide high assurance may suffer from such phenomena. Based on the common software-aging-related faults in fault-tolerant systems, a behavior model of a double-version fault-tolerant software system is established using Markov reward model. The performance of the system such as expected service rate in steady state is evaluated and the sensitivity analysis of some parameters is performed.
