C-Fuzzy Random Variables and their Stochastic Orderings

This paper deals with the study of stochastic orderings for special kind of fuzzy random variables so-called triangular fuzzy random variables. To this end, first we will introduce the concept of c-fuzzy random variables. Then, the traditional definition of usual stochastic orderings were extended for c-fuzzy random variables. Also, the upshifted hazard rate orderings and upshifted mean residual life orderings as well as the relationship between them has been studied in this context.
