An Approach to Group Decision Making Based on Incomplete Linguistic Preference Relations

This study not only applies Multi-Criteria Decision Making with Incomplete Linguistic model (InlinPreRa) and uses horizontal, vertical and oblique pairwise comparison algorithms to construct but also expansion group decision making model. When the decision maker is carrying out the pairwise comparison, the following problems can be avoided: time pressure, lack of complete information, the decision maker is lack of this professional knowledge, or the information provided is unreal and thus it is difficult to obtain information.
