Abstract | Many hardware reliability models and software reliability models have been developed to address failures in hardware subsystems and software subsystems, respectively. However, the interactions between hardware and software are often neglected. In this study, system failures are classified into three categories: hardware failures, software failures and hardware-software interaction failures. In particular, we classify hardware-software interaction failures into two categories: hardware-induced software failures and software-induced hardware failures. We develop a Markov-based unified system reliability model accounts all categories of system failures. The impact on system reliability as the changes of transition parameters is illustrated by numerical example.
