Group Decision Making for Different Fuzzy Preference Relations
In each group decision making, due to the interactions of the different points of view or individual characters, even for the same decision problem, decision makers may present different judgments of preference with uncertainty values as entries, such as fuzzy numbers, triangular fuzzy numbers, interval fuzzy numbers, trapezoidal fuzzy numbers (Xiao, Fan, and Wang, 2002; Guo and Guo, 2005; Wang and Chuu, 2004; Jose, 2006; Zadrozny and Kacprzyk, 2006; Pasi and Yager, 2006; Gong and Liu, 2007a; Gong, Wu, and Cui, 2008). In consequence, resolving conflicts that arise from different preferences and finding a unanimously agreed upon preference as the collective opinion of the group is a very important issue in any environment involving uncertainty. At the present, the topic of group decision making with different preferences has attached great attention and interest from a wide spectrum of scholars.
