River and lake system connecting engineering scheme optimization model sensitivity analysis method

Abstract

The invention relates to a river and lake system connecting engineering scheme optimization model sensitivity analysis method, which comprises steps: an index system is built; a combination weighting method is built; a Vague value is determined; a Vague set scoring function model is primarily selected; the index attribute value change sensitivity is analyzed; the index weight change sensitivity is analyzed; and the best scheme is selected. Through combining subjective and objective weighting methods, based on the idea that the deviation between the combination weight and the original weight is as small as possible, the combination weight of each index is solved, advantages of the subjective weighting method and the objective weighting method are considered well, and the obtained combination weight is more in line with actual demands. Robustness analysis on a decision result of the Vague set scoring function model under uncertainty and fuzziness of the attribute value and the weight value of each index based on a cloud model provides a new reference basis for objectively evaluating advantages and disadvantages of different Vague set scoring function models, and a decision maker is thus helped to select a proper Vague set scoring function model, and the best decision scheme is obtained.

Description

technical field [0001] The invention relates to a method for analyzing the sensitivity of an optimal model of a river-lake water system connection engineering scheme, which is an analysis method for water conservancy projects, and is an analysis method applied to planning of water conservancy projects. Background technique [0002] Due to the particularity of river and lake water system connectivity issues, attention should not only be paid to the impact of river and lake water system connectivity on the ecological environment and local areas such as transfer-out areas or transfer-out areas, but also its comprehensive impact on areas along the connectivity project and the entire connected system . At present, most studies focus on the exploration of the impact itself. There are relatively few studies on how to realize the quantitative comprehensive evaluation of the impact to optimize the connection project scheme of rivers and lakes. It is necessary to follow the laws of na...
