Abstract

In order to solve the uncertain multi-attribute group decision-making problem with the unknown attribute weights and Pythagorean fuzzy linguistic numbers attribute value, this paper proposed a two-stage interactive multi-attribute group decision-making method. This method not only considered group consistency and trust, but also regarded the uncertain attribute preference of the decision makers. Firstly, considering the preference of decision makers, this method divided the attribute set into required attribute set and optional attribute set. Secondly, this method constructed a two-stage interaction mechanism to ensure that the group consistency of the required attribute set reached the threshold. Based on the proposed interaction mechanism, it improved the level of consensus in the first stage and reduced the level of conflict in the second stage. Thirdly, it determined the weight of the decision makers under the required attribute set that the cumulative stability and cumulative interaction influence factors, while trust degree determined the weight of the decision makers under the optional attribute set. Finally, it designed the distance entropy of alternative to calculate the attributes weight, and the traditional VIKOR method ranked the optimal alternatives. A numerical example shows that this method is able to solve the multi-attribute group decision-making problem considering consensus and conflict levels.
