New properties of the switching points for the generalized Hukuhara differentiability and some results on calculus

Fuzzy Sets and Systems, 2021
This article provides a new characterization of the switching points for generalized Hukuhara differentiability and shows that the set of all switching points is at most countable.

The application of fuzzy Laplace transform by using generalized Hukuhara derivative

2021
Summary: In this research an analytic method is used to solve fuzzy heat equation with fuzzy initial values, which is based on generalized Hukuhara differentiability. At first, we define fuzzy laplace transform in \(t\) considering \(x\) as a parameter on fuzzy functions \(u(x, t)\) and their derivatives by using generalized Hukuhara differentiability.

Global existence of solutions to fuzzy partial hyperbolic functional differential equations with generalized Hukuhara derivatives

Journal of Intelligent & Fuzzy Systems, 2015
Abstract We combine two aspects, fuzzy mathematics and partial functional differential equations to get fuzzy partial hyperbolic functional differential equations in the sense of generalized Hukuhara-differentiability.

A RBF Neural Network System for Solving Fuzzy Optimal Control Problems Depending on Generalized Hukuhara Derivatives

New Mathematics and Natural Computation
In this paper, an intelligence approach based on radial basis function neural networks (RBFNNs) is used for solving fuzzy optimal control problems, utilizing the generalized Hukuhara derivatives. At the first step, we consider the fuzzy Euler–Lagrange conditions for both fuzzy unconstrained and constrained variational problems and Pontryagin maximum ...
