TLDR
The vertex method can avoid abnormality due to the discretization technique on the variables domain and the widening of the resulting function value set due to multi-occurrence of variables in the functional expression by conventional interval analysis methods.

Differential Evolution Methods for LU-fuzzy Arithmetic.

TL;DR: A di¬erential evolution (DE) algorithm to calculate the level-cuts of the fuzzy extension of a multidimensional real valued function to fuzzy numbers, designed to the case of di¤erentiable functions, for which a representation of the furry numbers is used to improve e¢ ciency and quality of calculations.

An extended analytical approach to evaluating monotonic functions of fuzzy numbers

TL;DR: This paper presents an extended analytical approach to evaluating continuous, monotonic functions of independent fuzzy numbers based on a parametric α-cut representation of fuzzy numbers and allows for the inclusion of parameter uncertainties into mathematical models.
