Abstract
Generally it is accepted that a user interface is very important for any applications and environment (Parsaye, K., et al., 1992.). Especially, the pairwise-comparison data of AHP is the most important element in AHP, and it makes time and effort applied to a decision maker. Furthermore, whenever it replies to a long time question, it is easy to be patternized, and the value of CI(Consistency Index) often becomes high. In this paper,we identify that the pairwise-comparison interface of AHP affect to the value of CI and then developed the new interface which is more nearly intuitive and is hard to be patternized.
