Abstract

The invention discloses an assembly-oriented intelligent quality tracing method, and belongs to the technical field of computer integrated manufacturing technologies and automation. The method comprises the following steps of with a product assembling process s a main line, constructing an assembly relationship network model covering all key production elements such as equipment, personnel, materials and suppliers; mining a model through a quality problem influence factor association relationship, extracting and quantifying the incidence relation of each production element in the assembly relation network model so thatthe full coverage of complex, dynamic, related and non-linear relations among influence factors of the product assembly quality problem is realized, and the problems that the assembly quality problem tracing method is single and the tracing effect is inaccurate and not timely are solved.

Description

technical field [0001] The invention relates to an assembly-oriented intelligent quality tracing method, which belongs to the fields of computer integrated manufacturing technology and automation technology. Background technique [0002] Most aerospace products have the characteristics of multiple varieties and small batches. The assembly process is mostly manual, with long processing lines and multi-model mixed-line production. And repetitive quality problems happen from time to time. At present, most of the research on quality traceability at home and abroad is focused on improving data collection. For example, using RFID or barcode technology to build a quality traceability system can improve data collection speed and reduce error rates. Using this technology in the supply chain can also improve traceability. high quality and efficiency, which makes it widely used in agriculture, food, manufacturing and other industries; there are not many researches on the algorithm of ...
