Abstract

The invention discloses an objective cloud matter element based industry comprehensive development level evaluation method, and belongs to the field of industry evaluation. The method is characterizedby comprising the following steps: determining the class quantity of the collected data, and classifying the data; calculating the minimum central value of compactness of each index and each class, so as to work out the adjacent boundary value of each class; analyzing the index; if the index does not have clear upper and lower limits, calculating the upper and lower limits according to the central value and the known boundary value, to obtain an interval of each index and each class; calculating the expected value Ex, entropy En and hyper entropy He to form a boundary cloud model of each class, then calculating the correlation degree between each to-be-evaluated scheme and the boundary cloud model of each class; weighting with the index weight to obtain the evaluation class of each scheme. The invention provides an objective cloud matter element based industry comprehensive development level evaluation method which realizes objective division of the class interval of the class boundary cloud model, theoretically eliminates the subjective effect of manual division, and remarkably improves the objectivity and evaluation accuracy.

Description

technical field [0001] The invention belongs to the technical field of industry evaluation, and in particular relates to an evaluation method of industry comprehensive development level based on objective cloud and matter elements. Background technique [0002] The existing comprehensive evaluation methods can be classified into three categories: methods based on fuzzy theory, methods based on probability statistics, and methods based on intelligent algorithms. However, the fuzzy theory uses expert experience, and the subjective factors are relatively large, which affects the objectivity of the results. In the probability statistics method, in the process of normalizing the expected value and standard deviation, the error in the selection of the reference value has a great influence on the objectivity of the evaluation result. Evaluation methods based on intelligent algorithms require a large number of training samples. Taking advantage of the dual uncertain reasoning char...
