A Systematic Literature Review on Software Reliability Modeling

Nowadays software systems have very important role in a lot of sensitive and critical applications. Sometimes a small error in software could cause financial or even health loss in critical applications. So reliability assurance as a nun-functional requirement, is very vital. One of the key tasks to ensure error-free operation of the software, is to have a quantitative measurement of the software reliability. So far, many models have been proposed for quantification of the software reliability. Each of these models has its advantages and limitations, so selecting the best proper model for various applications is very crucial. In this article, first, we define the basic concepts of reliability, then we classify different approaches of software reliability modeling and finally, based on the analysis of the advantages and limitations, compare different approaches and mention some challenges and issues.
