Evaluation of Water Conservancy Project Modernization Based on Rough Set Theory

The rough set theory is applied to evaluate water conservancy project modernization. Rough sets theory is used to analyze the raw data. Based on discretization of the measured data, the significance of attributes among rough sets is estimated instead of weight determination, and a relation data model about water conservancy project modernization assessment is established. A knowledge system is built through making attribute value into eigenvalue. The weight of a water conservancy project modernization assessment model is computed by analyzing the information and significance of forecasting method for the predicted object. The proposed approach overcomes the subjectivity of traditional evaluating method, and improves the precision of assessment for water conservancy project modernization. At last, an example is given to show the effectivitv and rationality of this new method
