When comparing five intuitionistic fuzzy methods used widely in decision-making, it can be found that utilizing different methods could get different results. Therefores, this paper uses combination evaluation sets to present the intuitionistic fuzzy combination multi-attribute group decision-making method based on the improved fuzzy Borda method, and studies the problem of unknown weight combination decision-making. This method is applied to pre-arranged plans decision-making, and it is found that the result of combination decision-making is in accord with the examination requirements, which proves the applicability of this method and that it can present a new idea or method to intuitionistic fuzzy decision-making.
