Fuzzy analytical hierarchy process

Firstly the paper pointed out the defects of AHP. Then, the paper introduced the concept of fuzzy consistent judgement matrix, and studied the properties of fuzzy consistent judgement matrix and the rationality to denote the important comparison of elements by fuzzy consistent judgement matrix, and the relation between the fuzzy consistent judgement matrix denoting the important comparison and the weight denoting the level of importance of element. On the basis of the research, the paper gave the principle and procedure of fuzzy analytical hierarchy process.
