Software Reliability Models
… is the basic assumption in building the software reliability models.</p> <p>Taking these factors into consideration, we have introduced an extra parameter, say c, in both the G -0 and Yamada <em>et al</em> models in order to get a new model. We find that a specific value of this new parameter …

Network reliability estimation
Computing the reliability of a network is a #P-complete problem, therefore estimation by means of simulation often becomes a favourable choice. In modern communication networks, link failure probabilities are usually small and hence network failures become rare events. This poses a challenge to …
