Reliability of Software Backup System in the Presence of Common Cause Failure

Abstract

The reliability of software system is very important. Common cause failures(CCF) have an influence on assessing the reliability of software. This paper studies the influence of CCF on software system reliability, and gives the quantitative method of common cause failure. We present the method of software reliability assessment in the presence of CCF. A case study is given to verify the effectiveness of the method.
