Generalized Variability Orderings among Nonnegative Fuzzy Random Variables [PDF]
Abstract and Applied Analysis, 2015 The variability ordering for more and less variables of fuzzy random variables in terms of its distribution function is defined. A property of new better than used in expectation (NBUE) and new worse than used in expectation (NWUE) is derived as an ...

Limit Theorems for Fuzzy Random Variables [PDF]
Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 2000 A strong law of large numbers and a central limit theorem are proved for independent and identically distributed fuzzy random variables, whose values are fuzzy sets with compact levels. The proofs are based on embedding theorems as well as on probability techniques in Banach space.

Journal of Mathematical Analysis and Applications, 1986 In a previous paper [ibid. 91, 552-558 (1983; Zbl 0528.54009)] the authors defined differentials for a fuzzy valued function. In this clearly thought and well-written paper they define an integral, or an expected value, of a fuzzy valued random variable. The definition is based on the integral of a set-valued function.

A perspective on the extension of stochastic orderings to fuzzy random variables [PDF]
, 2015 International audienceIn this paper we study how to make joint extensions of stochastic orderings and interval orderings so as to extend methods for comparing random variables, from the point of view of their respective location or magnitude, to fuzzy ...

Reliability Analysis in Presence of Random Variables and Fuzzy Variables
Journal of Applied Mathematics, 2015 For mixed uncertainties of random variables and fuzzy variables in engineering, three indices, that is, interval reliability index, mean reliability index, and numerical reliability index, are proposed to measure safety of structure.

Cramér-Rao Lower Bound for Fuzzy-Valued Random Variables
Austrian Journal of Statistics, 2016 In some point estimation problems, we may confront imprecise (fuzzy) concepts. One important case is a situation where all observations are fuzzy rather than crisp.

Chance-constrained programming with fuzzy stochastic coefficients [PDF]
, 2012 International audienceWe consider fuzzy stochastic programming problems with a crisp objective function and linear constraints whose coefficients are fuzzy random variables, in particular of type L-R.

A Strong Law of Large Numbers for Random Sets in Fuzzy Banach Space
Advances in Fuzzy Systems, 2020 The main purpose of this paper is to consider the strong law of large numbers for random sets in fuzzy metric space. Since many years ago, limited theorems have been expressed and proved for fuzzy random variables, but despite the uncertainty in fuzzy ...

Novel Construction of Copulas Based on (α,β) Transformation for Fuzzy Random Variables
Journal of Mathematics, 2021 The paper introduces a method for the construction of bivariate copulas with the usage of specific values of the parameters α and β (α,β transformation) and the parameters κ and λ in their domain.
