Method for software reliability assessment based on fuzzy fault tree analysis
软件可靠度的模糊故障树评定方法

The quantitative assessment of software reliability is one of the most important problem for software reliability project, this paper used firstly the qualitative and quantitative analyzing based on fault tree analysis of software, it proposed the method for fuzzy weight calculating and the primary and secondary ingredients compartmentalizing. It established the multi-grade fuzzy assessment model, discussed the enhanced and converging arithmetic, and proposed the expressions of reliability. This method presented its rationality of assessment configuration and validity of assessment arithmetic through testing and analyzing of an aero equipment's software, it could be used on quality and exploitation control engineering for software.
