Embodiment 1

[0131] This embodiment is a method for optimizing and sorting the engineering schemes of river and lake water system connectivity, the process is as follows figure 1 shown. The steps of the method described in this embodiment are as follows:

[0132] (1) Steps to establish the indicator system: through literature research, field investigation and evaluation, referring to the existing standard specification system, and according to the resource-society-economy-ecology-environment-engineering model, establish the principles for establishing the indicator system and establish river and lake water systems In the evaluation index system of the connectivity project scheme, the index value is determined according to the qualitative index and the quantitative index.

[0133] This embodiment takes a certain river and lake water system connection project as an application example to describe in detail this embodiment. The connectivity project plans three schemes P1, P2 and P3.

Abstract

The invention relates to a method for optimizing and sorting project schemes of river and lake water system connectivity, comprising: establishing an evaluation index system; calculating combination weights; calculating a variable set pattern recognition matrix; calculating the relative degree of membership of a single evaluation index; Membership degree; generate cloud model parameter table and cloud map; determine the final evaluation result. The present invention uses the combination of subjective weight and objective weight to unify the subjective and objective, and the weighting result is more reasonable and more in line with reality; the variable set method is used to solve the problem of fuzzy and clear indicators, and the cloud model is used for variable The uncertainty of the model has been analyzed, so that the optimal results can be selected more reasonably.

Description

technical field [0001] The invention relates to a method for optimizing and sorting engineering schemes of river and lake water system connectivity, which is a method for planning and analyzing water conservancy projects, and an analysis method for optimizing and sorting schemes of river and lake water system connectivity projects based on variable sets and cloud models. Background technique [0002] The purpose of the research on the connectivity of river and lake water systems is to analyze the characteristics of river and lake water systems and connectivity projects, taking into account the characteristics of multi-objective and multi-level engineering planning, based on the national strategic needs at the three levels of country, region, and river basin, to form river and lake water system connectivity. The feasibility scheme set of the project under multiple objectives and constraints, and then establish the index system of the scheme set, and optimize and determine the ...
