Evaluation method of object stability state based on umbrella-shaped three-dimensional structure

Abstract

The invention discloses an object stability state evaluation method based on an umbrella-shaped three-dimensional structure, provides a construction scheme of an umbrella-shaped three-dimensional structure index system and a two-dimensional node evaluation calculation method, and constructs a basic framework of an umbrella-shaped three-dimensional evaluation theory. When evaluation is carried out based on an umbrella-shaped three-dimensional evaluation theory, the method specifically comprises the following steps: S1, analyzing influence factors of a to-be-evaluated object; s2, decomposing the condition of the object in the objective world; s3, constructing an umbrella-shaped three-dimensional structure index system model; s4, calculating the stability degree by using a two-dimensional node method; and S5, representing and evaluating the stable state of the object. The umbrella-shaped three-dimensional evaluation theory provided by the invention is a method for evaluating the stability of objects by combining umbrella-shaped structural properties and mathematical theories, can be referenced by scholars in different fields, and can be further applied to wider fields.

AI Technical Summary

Problems solved by technology

[0003] At present, there are many evaluation methods and methods for a single problem, and the comprehensive evaluation method is a means of combining multiple models, but there is a lack of comprehensive system analysis and evaluation for problems in many fields, and the selection of indicators is not scientific, so it is difficult to provide decision makers with a comprehensive specific, objective, intuitive and specific optimal way to solve problems

[0004] Most of the evaluation systems and calculation methods constructed for different models cannot take into account the combination of local analysis and overall analysis of the system within the scope of their application

From the point of view of the method of constructing the index evaluation system for the things to be evaluated, most of the schemes are to construct the index system, and then obtain the overall evaluation results through the evaluation calculation method in the corresponding field, and it is impossible to start from the local part of the system for further evaluation It is also impossible to conduct overall and local modeling analysis on things at different structural levels, and to find the correlation between the whole and the parts, and between the parts and the parts in a complex system
