Abstract
The establishment of a scientific and reasonable mathematical evaluation model plays a vital role in the optimization of impervious design scheme of water conservancy projects. The steps of constructing the coupling model of information entropy and TOPSIS are analyzed. The seepage prevention design scheme of an urban artificial lake is comprehensively evaluated by using this model, so as to obtain the optimal scheme.
Highlights
The introductionA coupling model of information entropy and TOPSIS is established, and objective data mining and weight assignment are carried out for evaluation indexes in the model, so as to solve many problems, such as low accuracy of objective quantization of evaluation indexes weight and inability to objectively reflect the connection between data information and practical schemes
This work includes dimensionless processing of evaluation sample data and standardized processing of program evaluation value
For very large indicators, such as engineering effect, construction technology, investment, etc., the actual value is converted into the index evaluation value according to Formula (2)
Summary
A coupling model of information entropy and TOPSIS is established, and objective data mining and weight assignment are carried out for evaluation indexes in the model, so as to solve many problems, such as low accuracy of objective quantization of evaluation indexes weight and inability to objectively reflect the connection between data information and practical schemes
