Combining various solution techniques for dynamic fault tree analysis of computer systems
TLDR
We extend the DIFtree analysis capability to model several different distributions of time-to-failure, including fixed probabilities (no time component), exponential (constant hazard rate), Weibull (time-varying hazard rate) and log-normal. Expand
