A component based software reliability model
Jean Dolbec, Terry Shepard · 1995
This paper presents a component based software reliability model. The proposed model provides software system reliability estimates from the reliability of software components and the usage ratio of each component. Issues relating to the techniques for estimating the model parameters are discussed and the assumptions of the model are investigated. A component impact analysis method which could help in focusing testing efforts is also presented. 1 Introduction The aim of software reliability engineering is to model the failure behaviour of software systems to estimate and project reliability. Software reliability estimates serve many purposes. For instance, software reliability estimates can allow a contractor and a buyer to contractually agree to some tangible measure of reliability performance that a software system is expected to achieve. Also, software reliability estimates can allow software users to be selective about the software they purchase by considering the advertised soft...
