Open AccessA novel lifetime analysis of repairable systems via Daubechies wavelets
It is well-known that minimally repaired systems are characterized by non-homogeneous Poisson processes. When the underlying lifetime distribution function or its associated intensity function is completely kn...

Open AccessOptimal test case generation for boundary value analysis
Boundary value analysis (BVA) is a common technique in software testing that uses input values that lie at the boundaries where significant changes in behavior are expected. This approach is widely recognized ...

Software reliability analysis via geometric de-eutrophication models with group data
In this paper, we focus on a pure birth process to describe software fault counts, called the geometric de-eutrophication software reliability model (SRM), and provide some useful results to handle the softwar...

Effect of Epistemic Uncertainty in Markovian Reliability Models
This chapter introduces the moment-based epistemic uncertainty propagation in Markov models. The epistemic uncertainty in Markov models introduces the uncertainty of model parameters, and it can be propagated ...
