Fuzzy solution of system of fuzzy fractional problems using a reliable method

open access: yesAlexandria Engineering Journal, 2022
Under uncertainty, the analytical behavior of fractional differential equations is frequently puzzling and difficult to predict. As a result, it's necessary to develop a suitable, comprehensive, and highly effective theory to solve these challenges.

Fuzzy modelling on the depletion of forest biomass and forest-dependent wildlife population

open access: yesFranklin Open, 2023
This paper presents a system of non-linear differential equations describing the depletion of forest biomass and forest-dependent wildlife population caused by human population and its associated activities. The model incorporates the imprecise nature of

Fourth-Order Numerical Solutions for a Fuzzy Time-Fractional Convection–Diffusion Equation under Caputo Generalized Hukuhara Derivative

open access: yesFractal and Fractional, 2022
The fuzzy fractional differential equation explains more complex real-world phenomena than the fractional differential equation does. Therefore, numerous techniques have been timely derived to solve various fractional time-dependent models. In this paper,

Numerical Solution of Uncertain Beam Equations Using Double Parametric Form of Fuzzy Numbers

open access: yesApplied Computational Intelligence and Soft Computing, 2013
Present paper proposes a new technique to solve uncertain beam equation using double parametric form of fuzzy numbers. Uncertainties appearing in the initial conditions are taken in terms of triangular fuzzy number.
