Soft set theory, proposed by Molodtsov, has been regarded as an effective mathematical tool to deal with uncertainties. Recently, uncertainty measures of soft sets and fuzzy soft sets have gained attentions from researchers. This paper is devoted to the study of uncertainty measures of fuzzy soft sets. The axioms for similarity measure and entropy are proposed. A new category of similarity meas...

This paper presents a method for constructing belief functions from elicited expert opinions expressed in terms of qualitative preference relations. These preferences are transformed into constraints of an optimization problem whose resolution allows the generation of the least informative belief functions according to some uncertainty measures. Mono-objective and Multiobjective optimization te...

The use of uncertainty and criticality measures in network planning of engineering projects by PERT networks is limited in practice because of their unreliability or complexity. The measures appear as inappropriate to support the definition of contractual obligations when based on uncertain information. The author proposes new uncertainty and criticality measures based on the identification and...

In this note, stochastic comparisons of reliability measures and related functions are presented. Inequalities for uncertainty of a residual life distribution and certain modified cross-entropy or discrimination information measures under weighted models are established. Comparisons of the expected uncertainty about the remaining lifetime of a component for weighted conditional distributions an...

intolerance of uncertainty (iu) is increasingly conceptualized as a transdiagnostic factor underlying anxiety disorders and depression. current understanding of the relationship between intolerance of uncertainty and specific obsessive compulsive symptom domains remains limited. the purpose of the present study was to explore the prevalence of obsessive compulsive beliefs and intolerance of unc...

We investigate the impact of measures of uncertainty on firms’ capital investment behavior using a panel of U.S. firms. Increases in firmspecific and CAPM -based measures have a significant negative effect on investment spending, while market-based uncertainty has a positive impact.

Probabilistic measures of uncertainty have been obtained as functions of time and birth and death rates in a queuing process. The variation of different entropy measures has been studied in steady and non-steady processes of queuing theory. Keywords—Uncertainty, steady state, non-steady state, traffic intensity, monotonocity

We examine ways to measure the amount of information generated by a piece of news and the amount of uncertainty implicit in a given belief. Say a measure of information is valid if it corresponds to the value of news in some decision problem. Say a measure of uncertainty is valid if it corresponds to expected utility loss from not knowing the state in some decision problem. We axiomatically cha...
