This paper presents a methodology to represent and propagate epistemic uncertainties within a scenario-based earthquake risk model. Unlike randomness, epistemic uncertainty stems from incomplete, vague or imprecise information. This source of uncertainties still requires the development of...

This article first presents several formulas of chance distributions for trapezoidal fuzzy random variables and their functions, then develops a new class of chance model (C-model for short) about data envelopment analysis (DEA) in fuzzy random environments, in which the inputs and outputs are...

In this paper, we suggest a new method which is useful to study convergences of certain random upper semicontinuous elements by taking advantages of some well-known results concerning random cadlag functions. The suggested method is applied in the paper to developed strong laws of large numbers.
