Abstract

Abstract: Markov chain models of software use have been used successfully to test software and analyze the expected use of software systems. It is possible to augment a Markov chain usage model of the expected use of a medical system including hardware, software, and human componenents with information about the occurrence of hazardous conditions and the mitigation of hazardous conditions. The augmented Markov chain usage model, called a Safety model, presents significant opportunities for the quantitative analysis of aspects of system safety.
