Embodiment 1

[0081] Such as figure 1 As shown, a facility and equipment evaluation method based on probability distribution is a feature clustering and fuzzy comprehensive evaluation method based on information distribution, which is provided for facility and equipment evaluation under the condition of big data. Correlation analysis generates evaluation framework and fuzzy evaluation based on information distribution. The details are as follows:

[0082] 1. Generate an evaluation framework based on correlation analysis

[0083] S1, traverse the m features of the historical data to get the feature F i (i=1,2,…,m) maximum value max i and minimum min i ;

[0084] S2, standardize the historical data to obtain the data set normalData, the standardization method is as follows:

[0085]

[0086] where x' ij means x ij Normalized value, x ij Represents the feature F in the data set normalData i jth (j=1,2,…,n) value of (i=1,2,…,m); Indicates the feature F i The mean value of is calc...

Embodiment 2

[0150] A device for evaluating facilities and equipment based on information distribution includes a memory for storing executable instructions; a processor for executing the executable instructions stored in the memory to implement a method for evaluating facilities and equipment based on probability distribution.

[0151]The present invention fully analyzes the hidden information in the historical data when creating the evaluation framework, uses the correlation to classify the features, overcomes the artificial subjective influence, and at the same time well retains the data information; when calculating the evaluation object score, the data It is converted into a probability distribution to prevent information loss to a great extent in the form of information distribution. At the same time, the idea of ​​fuzzy evaluation is used for information fusion during information fusion, and the weight and information distribution of each child node are comprehensively calculated to c...

Abstract

The invention discloses a facility and equipment evaluation method and device based on probability distribution, and mainly solves the problems that in the prior art, an existing equipment and facility evaluation method evaluates correlation and independence between framework loss features and does not have expansibility. The facility equipment evaluation method based on probability distribution comprises the following steps: analyzing a correlation production evaluation framework according to historical data of facility equipment by an analyzer, and then scoring new data of the facility equipment according to the evaluation framework and outputting a result. By means of the scheme, the purposes of automatically establishing an evaluation framework, reserving correlation and independence between feature patterns, calculating scores and weights in an information distribution mode so as to prevent information loss and achieving multi-dimensional evaluation are achieved.

Description

technical field [0001] The invention relates to the technical field of computer learning, in particular to a method and device for evaluating facilities and equipment based on probability distribution. Background technique [0002] With the development of artificial intelligence, the demand for facilities and equipment in all walks of life is gradually increasing, and the dependence on facilities and equipment is also very large; when the facilities and equipment are performing monitoring tasks, their health status will greatly affect the facilities and equipment of normal operation. Therefore, in order to better maintain facilities and equipment and know the operating status of facilities and facilities in a timely manner, it is very necessary to establish an evaluation framework for facility and equipment monitoring. [0003] In recent years, many evaluation methods for facilities and equipment have emerged, such as: analytic hierarchy process, fuzzy evaluation method, ge...
