FAHP Based Comprehensive Evaluation System of Water Environment Security

Abstract:

The evaluation system of water environment security is improved by using fuzzy analytic hierarchy process (FAHP) in determining weights of various factors of the system. First, priority judgment matrix is FAHP uses three-scale method to construct and then fuzzy consistency judgment matrix is obtained. It overcomes many shortcomings of traditional AHP, such as the difficulty to scale when assigning weights, the need to conduct consistency testing, a large amount of calculation and low accuracy of calculation. It is effective and reasonable in the evaluation of water environment security.
