Embodiment Construction

[0060] figure 1 It is a schematic flow chart of the basic method of the present invention. Attached below figure 1 And embodiment the present invention is described in further detail.

[0061] Step 1, based on the cloud model, the expert scoring set X n Converting to expert evaluation cloud EC, the conversion process includes the following steps:

[0062] Step 1.1, according to 13 experts on the roadbed compaction index in the expressway, give the scoring results in the range of 0 points to 3 points, and form the expert scoring set: X 13 ={x 1 ,x 2 ,...,x 13} = {3,3,3,3,2,3,3,3,3,3,3,3,3};

[0063] Step 1.2, calculate expert score set X n The numerical characteristics of the expected E x , entropy E n and hyperentropy H e , and their calculation methods are shown in formulas (1), (2), and (3):

[0064] E x = 1 n Σ i = ...

Abstract

The invention relates to a method for evaluating the similarity between technical index cloud models of an expressway, and the method comprises the following stages: an expert evaluation cloud generation stage based on the cloud models, a standard evaluation cloud generation stage based on the cloud models, and a calculation stage of the similarity between two types of clouds. Compared with a conventional similarity evaluation method, the method provided by the invention irons out the defect that a conventional similarity comparison method based on vectors has to carry out the strict matching of the attributes of objects, optimizes an algorithm, and improves the calculation precision. Meanwhile, the method reduces the time in selecting, ordering and combining the cloud droplets, and improves the calculation efficiency of the similarity between the cloud models.

Description

technical field [0001] The invention relates to a method for judging the similarity between cloud models of expressway technical indicators, in particular, using a distance algorithm to calculate the similarity between two different cloud models so as to judge the key indexes in the expressway. Background technique [0002] Affected by expert knowledge, the evaluation of the criticality of a highway engineering quality inspection index has certain randomness, ambiguity and subjectivity, which brings great difficulties to the qualitative judgment of whether the index is critical. [0003] The cloud model provides an important theoretical tool for the description of such randomness, fuzziness and subjectivity quantitative evaluation data, and has been well applied in the field of traffic engineering. However, there is no mature and reliable solution to the problem of equivalent conversion between random, fuzzy, and subjective quantitative evaluation data to objective qualitati...
