A 3D model-based multi-attribute decision-making quality detection method

Abstract

The invention discloses a method for multi-attribute decision making quality detection based on a three-dimensional model. The method comprises the steps of selecting a product model, and performing parameter extraction on a three-dimensional quality model of products of this model; performing feature identification of complex device product parts; constructing a multi-attribute decision making quality detection model; and determining digitized quality detection rules. According to the method, functions of parameter extraction of a three-dimensional design model of the complex device product parts, feature identification, reconstruction, comparison, on-line query, man-machine interaction, intelligent analysis, knowledge base calling, data storage and detection feedback and the like are achieved; the shackle of incompatibility of a conventional quality detection method and a modern digitized quality detection method is broken through, conventional detection means can be fused into a new model of digitized quality detection, disadvantages of the conventional method and the digitized method are avoided, advantages of both are brought into full play, and detection efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of equipment detection, in particular to a three-dimensional model-based multi-attribute decision-making quality detection method. Background technique [0002] The development and production of complex equipment has the characteristics of multiple varieties, small batches, high requirements, and high risks. Under this production mode, manufacturing enterprises, especially production and manufacturing workshops, need to reflect the equipment's use environment, functions, behaviors, fault status and detection more realistically. process and result. This makes it difficult for the traditional single fault injection quality inspection method to fully meet the needs of complex equipment quality inspection. [0003] How to use advanced quality monitoring methods to improve the current detection mode of complex equipment, reduce production risks, optimize operating efficiency, improve market competitiveness, and finally re...

AI Technical Summary

Problems solved by technology

[0006] At present, the research on digital quality inspection methods for complex equipment multi-attribute decision-making is not sufficient, so the implementation of digital quality inspection methods in enterprises has only played a point of promotion, but has not played a comprehensive role in promotion; from the digital quality inspection of existing enterprises From the perspective of the application of the method, not every enterprise that has implemented digital quality inspection can achieve the desired results. The important reasons for the different results after the implementation of digital quality inspection include: failure to establish a set of digital quality inspection tools that are suitable for the production mode of the enterprise. Quality inspection rules; quality inspection technology that only considers a single attribute cannot meet the current enterprise needs; standardized digital quality inspection operating procedures are not adopted, etc.
