| Abstract: |
| 【Objective】Optimizing water-saving projects is critical to reducing their costs and detrimental impact on the environment and ecological systems. Many optimization algorithms are available, and the purpose of this paper is to present a method to optimally selecting proposals for complex multi-attribute and decision-making problems in water-saving irrigation projects. 【Method】 The optimal selection method was based on the VIKOR algorithm. It used the target difference rate to standardize the original data of each index, and the improved CRITIC method was conducted to rationally calculate the weights.【Result】Application of the method to a real case and its comparison with other methods revealed that the results obtained by the VIKOR method using different decision coefficients were consistent with that calculated from the fuzzy comprehensive evaluation method and the fuzzy matter-element model. The optimized scheme agreed well with the real case, indicating that the VIKOR method was feasible to solve the decision-making problems in optimally selecting proposals for water-saving irrigation projects.【Conclusion】The VIKOR method is simple, stable and computationally efficient, in addition to its high resolution. The decision coefficients in the method can be adjusted based on the significance of the project and the preferences of the decision makers. It is thus potential for application in optimizing water-saving irrigation as well as other engineering projects. |
