Mathematic description about random variable with fuzzy density function (FVFDF)
This paper presents a very individual approach to random variables coupled with fuzziness. Using a certain kind of interval techniques the authors introduce a so-alled fuzzy density random variable and discuss its expectation and variance. References ignore totally the well established progress on the field of random fuzzy variables since the starting papers by Kwakernaak or by Puri/Ralescu.
