Abstract: The consistency test is one of the critical components both in AHP and ANP. It is necessary to make sure if the judgment result is accuracy and reliable. This paper stated a specific process of consistency test in ANP with group judgment under intuitionistic fuzzy environment. A two steps de-fuzzification technique with intuitionistic fuzzy number reduction and generalized mean computation is proposed to apply in this study. The group consistency is also fully tested in two stages. This proposed process exposes that it is comprehensive and feasible. Besides, the application of maximum eigenvalue threshold method, a new consistency test index to check for the consistency, is an advantage because it reduces a lot of operations.
