Embodiment Construction

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0041] Traceability of complex product quality problems is a system engineering that goes through multiple links, such as troubleshooting and positioning, cause mechanism analysis, phenomenon recurrence, solution verification, and summary by analogy. Traditional data analysis and application of root cause traceability of quality problems are generally Abnormal point analysis of a single data of a single device at a certain sta...

Abstract

The invention provides a complex product quality problem tracing method and system. The tracing method comprises the following steps: receiving related problem data of a complex product quality problem; performing text recognition processing on the related problem data to obtain each problem entity and an association relationship between the problem entities, the problem entities being the problemdata after characterization processing; performing association processing on each problem entity according to the problem association relationship to generate a quality problem knowledge graph; and tracing the source data of the quality problem according to the quality problem knowledge graph. The tracing method provided by the invention is based on a natural language processing technology, multi-dimensional correlation analysis technology mining is carried out on a complex product quality case, and the efficiency of tracing the complex product quality problem is improved; and through the continuously improved quality problem knowledge graph, expert knowledge of quality problem analysis is solidified step by step, services such as analysis path prediction and typical problem early warningare provided, and a big data technical support is provided for complex product quality guarantee.

Description

technical field [0001] The present invention relates to the technical field of data processing, and more specifically, to a method and system for tracing complicated product quality problems. Background technique [0002] Complex product (Complex Product, CoP) is a kind of large-scale product, system or infrastructure with high R&D cost, high technical requirements, single-piece or small-batch customized production, which includes large-scale communication systems, aerospace systems, large ships, electric power Network control systems, high-speed trains, and large-scale weapons and equipment are closely related to modern industry and directly affect a country's comprehensive national strength and core competitiveness. Strengthening quality management based on data analysis and mining is a new direction for the high-quality development of the big data industry in the field of complex product manufacturing. Typical examples include the fourth-generation U.S. fighter F / A-22 "Ra...
