Embodiment Construction

[0028] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] The invention provides a method for evaluating the quality of electromechanical products based on the quality characteristic gene theory, such as figure 1 shown, including the following steps:

[0030] S1. Analyze the influencing factors of product quality characteristics (operator, machine equipment, raw materials, processing technology, environment and measurement factors, 5M1E), and construct a gene model of product quality characteristics.

[0031] Product quality characteristics can be characterized by product quality characteristics genes; 5M1E, as an influencing factor of product quality characteristics, is the basis for the formation of product quality characteristics.

[0032] In the embodiment of the present invention, the following factors are mainly considered for the construction of the product quality characteristic gene:

[0033] ...

Abstract

The invention discloses a mechanical and electrical product quality evaluation method based on a quality characteristic gene theory. The quality characteristic gene theory is introduced into product quality evaluation against the problems that traditional product quality evaluation methods based on quality inspection are complicated in process, high in operation cost and the like. According to the method, a product quality characteristic gene modeling method based on product quality characteristic influence factors (operators, machines, materials, processing technologies, environments and measurement, 5M1E) is constructed with a mechanical and electrical product processing and manufacturing process, namely a quality forming process being a sally port; weights of the quality characteristic influence factors are quantized according to a fuzzy theory, symbolic encoding is performed on the quality characteristic influence factors in combination with a significance threshold value, and then symbolic expression of product quality characteristic genes is obtained; and last, a product quality evaluation method based on similarity analysis of the product quality characteristic genes is proposed according to a similarity theory.

Description

technical field [0001] The invention belongs to the technical field of quality evaluation of electromechanical products, and in particular relates to the design of a quality evaluation method of electromechanical products based on quality characteristic gene theory. Background technique [0002] With the advancement of technology, the competition among enterprises is becoming more and more fierce. For manufacturing enterprises, this kind of competition boils down to the competition between product quality and function. Therefore, product quality assurance has become an important factor for enterprises to improve their core competitiveness. Among them, product quality evaluation is an important part of product quality investigation. At present, the product inspection method is generally adopted for the quality evaluation of ex-factory products, that is, the batch product samples are obtained by sampling and the quality characteristics of the sample products are inspected, so...
