Soft Techniques for Aggregation of Fuzzy Preferences under Group Decision Making
群决策中模糊偏好集结的软技术

Based on the author's paper, this paper aims at exploring the soft techniques of the indirect solution for group decision making with fuzzy linguistic preference. At first, the concept of coincidence degree and it's entropy between fuzzy sets is given and used to produce soft techniques for aggregation of the fuzzy linguistic preference. Next, fuzzy expected value and fuzzy majority are applied to give generating techniques for the indirect solution of group decision making. At last, a computing example is illustrated. The marked feature of this model is the use of the criteria with entropy and the measure with coincidence degree to generate indirect solving techniques of group decision making.
