“…To quantify the attitude of DMs in a continuous ranging scale to reflect the pessimistic attitudes to indifferent attitudes in construction of the trust relationships, the authors in[94] proposed an attitudinal trust degree, which makes use of an ordered weighted average operator guided by a unit-monotonic function. Considering the risk attitude of DMs in alternative ranking through an evidential reasoning methodology[95] and construction of linguistic quantifiers based upon the attitude of DMs[96] are of recent trends in the design of attitude-based feedback mechanisms.As the last category of behavioral mechanisms, we review some recent advances on managing the non-cooperative behavior of DMs towards consensus reaching by means of a feedback mechanism. The non-cooperative behavior refers to the case, in which the inconsistent DMs are reluctant to modify their opinions according to the provided recommendations through the feedback mechanism.…”
