Detection planning method based on quality function allocation

Abstract

The invention provides a quality detection planning method based on quality function configuration, comprising the steps of calculating the importance weight of each process in the production processof a product; summarizing the inspection items of important working procedures; establishing the relationship matrix between important process and inspection items, and calculating the correlation coefficient between important process and inspection items; the autocorrelation matrix of the detection items is established and the correlation coefficient between the two detection items is calculated.According to the correlation coefficient between the important process and the inspection item, the importance of the inspection item is calculated. The higher the importance of a detection project is, the higher the configuration priority is. The present invention solves the problem that the existing detection planning of the existing enterprise is mainly based on the subjective judgment of theengineer's own experience, and has subjectivity and one-sidedness, and lacks a quantitative description method for judging the importance degree of each working procedure and systematic detection planning measures.

Description

technical field [0001] The invention belongs to the field of quality inspection planning, and in particular relates to a quality inspection planning method based on quality function configuration. Background technique [0002] The production and operation activities of industrial enterprises are a complex process. Due to the influence of various factors such as personnel, equipment and materials, it often causes fluctuations in product quality and even produces substandard products. In order to ensure product quality, it is necessary to conduct quality inspections on various production links and production processes such as raw materials, purchased parts, outsourced parts, blanks, semi-finished products and finished products in the production process. Under the complex manufacturing process conditions where multiple production modes such as multiple varieties, single pieces, small and medium batches, and large batches coexist, the production resources of the enterprise are l...
