Dependency definitions for quantitative human reliability analysis

Webb1 okt. 2016 · This assumes that the dependence between two human failure events varies at discrete levels between zero and complete dependence (as defined by THERP). Dependence in THERP does not consistently span dependence values between 0 and 1. In contrast, probabilistic dependence employs Bayes Law, and addresses a continuous … Webbdoes–because of a human act–the cause will very likely be identified as a human error" (p. 149). He stresses the point that faults and errors "can only be defined with reference to human intentions or expectations" (p. 149). One important aspect in this definition is the 'reference to human intentions or expectations'. Let us discuss the WebbReferences. 1 Swain, A. D.; Guttman, H.
