Measures of Risk on Variability with Application in Stochastic Activity Networks

摘要

We propose two simple measures of variability of some of the more commonly used distribution functions in the class of New-Better-than-Used in Expectation (NBUE). The measures result in a ranking of the distributions, and the methodology used is applicable to other distributions in NBUE class beside the ones treated here. An application to stochastic activity networks is given to illustrate the idea and the applicability of the proposed measures.
