Study on Component-based Software Safety Analysis
构件化软件系统安全性分析技术研究

Many obscure expressions and uncertainties exit during the process of safety analysis for complicated safety-critical software,while the theory of fuzzy sets and subjective evaluation is an effective methodology to deal with these problems.We presented the fuzzy expressions of the software safety factors,then analyzed the safety score of single component.After that,we synthesised the safety score of subsystem and system quantitatively by using the fuzzy operations and evidential reasoning approach.Finally,a...
