5. Conclusion
Thus with an intensive analysis, it is clearly observed that Nancy and Garg’s proposed method [10, Section 3, Def. 3.1, pp. 379] for the ranking of two SVNS as well as the Nancy and Garg’s proposed method [10, Section 3, Def. 3.2, pp. 381] for the ranking of two IVNS fails to find the correct ranking order and hence stands invalid. To propose the valid methods for the same may be considered as a challenging future research problem.
