## Solving Fuzzy Fractional Biological Population Model using Shehu Adomian Decomposition Method

Received Date:05 February 2023, Accepted Date:11 August 2023, Published Date:04 December 2023

## Abstract

Objectives: In applied sciences and engineering, fuzzy fractional differential equations (FFDEs) are a crucial topic. The main objective of this study is to find the exact solution of the nonlinear Fuzzy Fractional Biological Population Model (FFBPM). In the Caputo concept, fractional derivatives are regarded. Methods: For nonlinear problems, the Shehu transform is difficult to exist. So, the Shehu transform is combined with the Adomian decomposition method is called the Shehu Adomian Decomposition Method (SHADM) and has been proposed to solve the FFBPM. Findings: The main favor of this method is rapidly converging to the exact solution for nonlinear FFDEs. The theoretical proof of convergence for the SHADM and the uniqueness of the solution is given. Novelty: Adomian polynomials are used for nonlinear terms. Figures and numerical examples demonstrate the expertise of the suggested approach. This method is applied for both linear and nonlinear ordinary and partial FFDEs. The proposed approach is rapid, exact, and simple to apply and produce excellent outcomes.

Keywords: Caputo fractional derivative, Shehu transform, triangular fuzzy number, Fuzzy Fractional Biological Population Model, Shehu Adomian decomposition method
