An approach to measuring and assessing dependability for critical software systems

D. Tang, H. Hecht
Proceedings The Eighth International Symposium on Software Reliability Engineering  
1 Traditional software testing methods combined with probabilistic models cannot measure and assess dependability for software that requires very high reliability (failure rate < 10 /hour) and availability  ...  to quantify dependability for a category of critical software with such high requirements.  ...  Not only can the approach be used to quantify dependability for critical software systems in which rare conditions are the major threat to the system dependability, but it can also contribute significantly  ...
