Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention.

[0031] A block weight selection method for patrol map based on improved gray system theory, the specific technical part is as follows:

[0032] The correlation degree analysis method in the gray system theory is a new factor analysis method, which analyzes the correlation degree among multiple factors in the system by comparing the geometric relationship of the system statistical series, that is, the relationship between the time variables that characterize the factors is considered to be The closer the geometry of the represented curves is, the closer the development and change trends of the factors are, and thus the greater the degree of correlation between them is.

Abstract

The invention relates to an electric power line patrol graph block weight selecting method based on an improved grey system theory and belongs to the field of patrol inspection. The method has the advantages that the correlation degree of multiple elements in a system is analyzed by comparing system statistical series geometrical relationships, that is to say, the closer the geometrical shapes ofcurves indicated among the time variables scoring the elements is, the closer the element development and change state is, and the correlation degree between the two is high; for a system with quantified targets and indexes, the correlation degree between the sub-elements and targets is calculated by using improved grey correlation, normalization processing is performed on the correlation degree to obtain values, namely weights, the influence degree of the indexes on the targets can be determined, the influence directions on the targets can be reflected, and high objectivity is achieved.

Description

technical field [0001] The invention relates to the field of electric power system inspection, in particular to a weight selection method based on an improved gray system theory correlation degree analysis method in the electric power inspection process. Background technique [0002] In the calculation of line inspection efficiency of power line inspection personnel, the weight selection is a very important factor, which will directly affect the final work efficiency analysis results. [0003] The establishment of the weight should be the response of the objective information of the factors, and also the response of the subjective judgment of the decision-making. If the weights are determined by methods such as subjective experience, it may be affected by the knowledge of the decision maker or other negative influences, so that the ranking of the schemes may have great subjective arbitrariness. At present, there are some classic index weight selection methods, such as Delph...
