Absolute derivative of set-valued maps [PDF]

open access: yes, 2022
The aim of this article is to develop a differential calculus for setvalued functions with values in metric spaces of the family of all compact and convex subsets. Using only the metric Hausdorff on metric spaces and without using the Hukuhara difference,

Constructing analytical estimates of the fuzzy fractional-order Boussinesq model and their application in oceanography

open access: yesJournal of Ocean Engineering and Science, 2023
The main idea of this article is the investigation of atmospheric internal waves, often known as gravity waves. This arises within the ocean rather than at the interface.

Analytic Fuzzy Formulation of a Time-Fractional Fornberg–Whitham Model with Power and Mittag–Leffler Kernels

open access: yesFractal and Fractional, 2021
This manuscript assesses a semi-analytical method in connection with a new hybrid fuzzy integral transform and the Adomian decomposition method via the notion of fuzziness known as the Elzaki Adomian decomposition method (briefly, EADM). Moreover, we use

Full averaging of fuzzy impulsive differential inclusions [PDF]

open access: yesSurveys in Mathematics and its Applications, 2010
In this paper the substantiation of the method of full averaging for fuzzy impulsive differential inclusions is studied. We extend the similar results for impulsive differential inclusions with Hukuhara derivative (Skripnik, 2007), for fuzzy ...

On Maximal and Minimal Solutions for Set-Valued Differential Equations with Feedback Control

open access: yesAbstract and Applied Analysis, 2012
In this paper, we present the existence of extremal solutions of set-valued differential equations with feedback control on semilinear Hausdorff space under Hukuhara derivative which is developed under the form DHX(t)=F(t, X(t),H(t,X(t))), X(0)=X0,  for ...

Solution of an Economic Production Quantity model using the generalized Hukuhara derivative approach

open access: yesScientia Iranica, 2021
In this study, an economic production quantity (EPQ) model with deterioration is developed where the production rate is stock dependent and the demand rate is unit selling price and stock dependent. The low unit selling price and more stocks correspond high demand but more stock corresponds to slow production because of the avoidance of unnecessary ...

New variants of fuzzy optimal control problems

open access: yesAsian Journal of Control, Volume 28, Issue 1, Page 116-123, January 2026.
Abstract This study introduces a groundbreaking approach to optimal control problems by incorporating fuzzy conformable derivatives. Our primary goal is to identify the optimal control strategy that maximizes fuzzy performance indices while adhering to fuzzy conformable dynamical systems.

Random set-valued functional differential equations with the second type Hukuhara derivative [PDF]

open access: yesDifferential Equations & Applications, 2013
This paper concerns with the initial value problem for random set-valued functional differential equations with the second type Hukuhara derivative (RSFDEs). By using the techniques of successive approximations, the existence and uniqueness of solutions are established. Two kinds of boundedness of the solution are also established.
