The study aims to obtain a semi-analytical solution for the fuzzy time-fractional Fisher equation (FtfFE) considering uncertain coefficients involved in initial condition as a triangular fuzzy number (TFN).
Fractional reduced differential transform method (FRDTM) has been used to find the convergent series solution for the time-fractional Fisher equation in both crisp and fuzzy environment.
The convergent series solution has been found using FRDTM and the obtained fuzzy FRDTM solution is compared with exact for integer case α = 1. The lower and upper bound solutions of FtfFE for different spatial and temporal values at α = 0.75 are provided. The relation between both bounds of the solution and fractional order α is evaluated.
Application of FRDTM to the fuzzy time-fractional Fisher equation to study the behavior and other characteristics of the solution.
