It usually exists that n individuals are required to rank m objects. During ranking, pair wise comparison, as a relative measure, is a useful and commonly used technique. Especially, it is a basic and core ingredient in the Analysis Hierarchy Process (AHP). However, strict requirements of the Nine-point Scale pair wise comparison in the AHP limit its application. In this study, we explore a 0, 1 Two-point Scale pair wise comparison and a model which are used for n individuals ranking m objects. The proposed model can not only be applied for n individuals to rank m objects but also extend the application of the AHP.
