| Abstract: |
| The use of set pair analysis in determining the establishment of an integrated assessment model index weight, at first, the rough set theory in the attribute importance to determine methods and expert ratings of the Combination, and then use game theory methods to determine the right set of weights and integration, to be Irrigation comprehensive evaluation index weights. In this study, set to the analysis of the Fenhe River in Shanxi Province Irrigation District in 2004 to run a more accurate status of a comprehensive evaluation rating of good; evaluation results show that the set pair analysis method has a higher resolution and greater practicality, with a do not lose the data center information, evaluation results with the actual situation is even more consistent with the advantages of a comprehensive evaluation of operational status for the Irrigation District provides a simple and appropriate evaluation methods. |
