In this paper, we train group decision-making problems created on intuitionistic fuzzy inclination associations. We suggest a new attitude to estimate the qualified reputation weights of authorities by calculating the uncertain evidence of intuitionistic fuzzy inclination associations and the normal similarity grade of one separable intuitionistic inclination association to the others. This new attitude takes both the ‘impartial’ and ‘internal’ evidence of authorities into deliberation. Then intuitionistic fuzzy inclination relations were assimilated by us the weights of authorities into the specific and progress a relative similarity method to originate the significances of substitutes and best of the substitutes. The contrast analysis with additional methods by mathematical illustrations demonstrates the realism and helpfulness of the projected approaches.
