Embodiment 1

[0131] This embodiment is a method for prioritizing and sorting river-lake water system connection engineering schemes. 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 an index system: through literature research, field investigation and evaluation, refer to the existing standard and normative system, and establish the principles of index system establishment according to the resource-society-economy-ecology-environment-engineering model, and establish the river and lake water system The evaluation index system of the connection engineering scheme determines the index value based on the qualitative index and the quantitative index.

[0133] In this embodiment, a certain river-lake water system connection project is taken as an application example to describe this embodiment in detail. The connectivity project plans 3 plans P1, P2 and P3.

[0134] In this step, considering that in the eva...

Abstract

The invention relates to a river and lake water system connecting engineering scheme preferable ordering method comprising the steps that an evaluation index system is determined; the combination weight is calculated; a variable set mode identification matrix is calculated; the relative membership of a single evaluation index is calculated; a rank feature value and the integrated relative membership are calculated; a cloud model parameter table and a cloud graph are generated; and the final evaluation result is determined. The subjective weight and the objective weight are combined so that the subjective and the objective are enabled to be unified and the weight assignment result is more reasonable and further meets the actual situation; and the blur clarifying problem of the index is solved by using the variable set method, and the uncertainty of the variable model is analyzed by using the cloud model so that the scheme preferable result can be more reasonably selected.

Description

Technical field [0001] The invention relates to a method for optimal sequencing of engineering schemes for connecting river and lake water systems, which is a water conservancy project planning analysis method, and an analysis method for optimal sequencing of engineering schemes for connecting river and lake water systems based on a variable set and cloud model. Background technique [0002] The purpose of the study on the connection of rivers and lakes is to analyze the characteristics of the rivers and lakes and the connected engineering, taking into account the multi-objective, multi-level and other characteristics of the project planning, based on the national strategic needs of the country, region, and basin, to form the connection of rivers and lakes. A set of feasible schemes for the project under multiple objectives and multiple constraints, and then an indicator system for the scheme set is established. Through simulation calculation and evaluation analysis, the planning ...
