4. The gradient visualization analysis corroborated the mathematical results, showing that the top ranked FGM indeed exhibited superior thermal gradient management and reduced thermal stresses. 5. The proposed framework can be effectively adapted to various FGM selection problems across different application domains by adjusting the criteria and their weights according to specific requirements. The main theoretical contribution of this study is the creation of a unique neutrosophic assessment method that incorporates numerous evaluation sites along the material gradient in order to account for the gradient nature of FGMs. Furthermore, the proposed neutrosophic aggregation method effectively combines expert judgments with quantitative material data, addressing a significant challenge in FGM evaluation. From a practical perspective, the framework provides materials engineers and designers with a systematic decision support tool for selecting optimal FGM compositions tailored to specific application requirements. The comprehensive consideration of thermal, mechanical, manufacturing, and economic factors ensures balanced decision-making that aligns with both technical and practical constraints. In summary this research presents a potential method for tackling the intricate multi-criteria decision-making problem in FGM selection the neutrosophic TOPSIS framework. The effectively handling the uncertainties inherent in FGM evaluation while comprehensively considering various performance aspects, the framework contributes to advancing the practical implementation of these innovative materials in demanding applications.
