Raw relation sets and multiperson decision making

In this paper, multiperson decision making is explored based on raw relation sets (Chen, 2002), in which three types of basic order relationships between any two objects are used to define the order relationships among a set of objects. Different order relationships among the same set of objects may be produced by different evaluators (or evaluation criteria) and there is also an order relationship among the evaluators themselves. In this paper, all evaluators are assumed to be of the same importance. This method emphasizes using qualitative (or un-weighted) order relationships but it is also capable of handling weighted order relationships.
