On Distribution Characteristics of a Fuzzy Random Variable
In this paper, rst a new notion of fuzzy random variables is introduced. Then, using classical techniques in Probability Theory, some aspects and results associated to a random variable (including expectation, variance, covariance, correlation coecient ...

Perceptionization of FM/FD/1 queuing model under various fuzzy numbers
We present a FM/FD/1 queuing model with unbounded limit under different fuzzy numbers. The arrival (landing) rate and service (administration) rate are thought to be fuzzy numbers such as triangular, trapezoidal and pentagonal fuzzy numbers.

Estimation of Hazard Rate and Mean Residual Life Ordering for Fuzzy Random Variable
L2-metric is used to find the distance between triangular fuzzy numbers. The mean and variance of a fuzzy random variable are also determined by this concept.

Cramér-Rao Lower Bound for Fuzzy-Valued Random Variables
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.

(Quantum) Space-Time as a Statistical Geometry of Fuzzy Lumps and the Connection with Random Metric Spaces [PDF]
We develop a kind of pregeometry consisting of a web of overlapping fuzzy lumps which interact with each other. The individual lumps are understood as certain closely entangled subgraphs (cliques) in a dynamically evolving network which, in a certain ...

Solving the General Fuzzy Random Bilevel Programming Problem Through
This paper addresses the general fuzzy random bilevel programming problem in which not only both objective functions, but also the constraints contain fuzzy random variable coefficients.

Variable grouping in multivariate time series via correlation [PDF]
The decomposition of high-dimensional multivariate time series (MTS) into a number of low-dimensional MTS is a useful but challenging task because the number of possible dependencies between variables is likely to be huge.

Fuzzy directed divergence measure and its application to decision making [PDF]
Divergence or relative information is a measure of information associated with two probability distributions of a discrete random variable which is based in Shannon entropy.
