| Abstract: |
| Combined with the actual condition of Jiaokou large-scale irrigation district (ID) pumping Weihe River in Shaanxi Province, based on the overall survey, established the evaluation index system as 6 first-level indicators and 27 secondary indicators, utilized the G1 method and variation coefficient method to determine the subjective and objective weights respectively, and then utilized the game theory to fuse and gather the subjective and objective weights, finally determined a set of reasonable comprehensive weights. Using the ideal solution method of the grey relation theory, carried out the comprehensive evaluation for the operation condition of Jiaokou ID, and developed the calculating software of comprehensive evaluation for the operation situation in a arge-scale ID. Taking the Jiaokou ID as the case study, carried out the test and verify. The evaluation software results showed that in 2007，2008，2009，2010，2011 and 2012，the relative closeness degree in Jiaokou were 0，0.1166，0.2468，0.4275，0.6102 and 0.7783 respectively, and the operation status levels were poor, medium, medium, good, good and good, respectively. The evaluation results were basically in accordance with the actual calculated results. With time going, the evaluation level was gradually improved from poor to good and operation condition was better and better in Jiaokou ID. Which was also in accord with the objective reality and the developing rule in this ID. irrigation district The comprehensive evaluation software evaluation results for operation condition in large-scale ID was reliable and correct, it can be greatly improved the efficiency of comprehensive evaluation in irrigation district. |
