Problems solved by technology

[0009] In the process of comprehensive evaluation of multi-objective scenario decision-making, when determining the weight coefficient of the evaluation index, there is a shortage of only considering the subjective or objective aspects, or the incompleteness of the weight coefficient of the evaluation index obtained by simply summing up the subjective and objective aspects. Therefore, through comprehensive consideration Subjective and objective information

Embodiment Construction

[0081] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0082] like figure 1 As shown, taking the comprehensive evaluation of the Yongding River ecological restoration scenario construction as an example, the specific application of the multi-objective comprehensive weight scenario comparison and decision-making method includes the following steps:

[0083] 1. Objectives and evaluation indicators of Yongding River ecological scenario construction:

[0084] Typical evaluation indicators were selected through actual investigation and analysis, and different watershed ecological restoration scenarios were constructed, and the resulting scenario plans were evaluated. Here, three objectives were established for comprehensive evaluation, namely, water environment objectives, ecological objectives, social and economic goals; at the same time, through comprehensive analysis, typical, controllable and quantifiable evaluation i...

Abstract

A multiple target comprehensive decision evaluation method based on a scene comprises steps of establishing decision schemes of various scenes for the actual problem, and establishing a target set and a an evaluation set; determining the base weighing of evaluations; distinguishing uncertainty factors of objective aspects and subjective aspects, which influence evaluation weighing coefficients, and regarding uncertainty factors as main control factors adjusting weighing of evaluations; according to the actual application environment and different decision evaluation targets, determining weighing coefficients of evaluations of all main control factors and relative important weighing coefficients which are occupied by the base weighing and all main control factors during evaluation; calculating comprehensive weighing coefficients of all evaluations; and reducing the overlapping information among data through a comprehensive evaluation method of integrated comprehensive weighing and main component projection, and comprehensively evaluating the multiple target decision. By the aid of the method, the information of evaluations can be considered comprehensively, the information of evaluations is complementary, and the accuracy of evaluation results is improved.

Description

technical field [0001] The invention relates to a scenario-based multi-objective comprehensive decision-making evaluation method. Background technique [0002] In the multi-objective comprehensive decision-making evaluation, due to the incommensurability and contradiction between the goals of the multi-objective decision-making problem, the evaluation indicators belonging to the decision-making evaluation objectives occupy different degrees of importance in the decision-making evaluation, and their importance will affect the decision-making evaluation. results have a significant impact. Decision makers need to consider determining the weight of each evaluation index according to the importance and priority of different goals. The assignment of multi-objective weight coefficients is an important part of multi-objective decision-making, which determines the accuracy of multi-objective synthesis to a considerable extent. Therefore, the weight coefficient plays an important ro...
