Abstract

The invention discloses a knowledge acquisition template for product reliability design and a criteria extracting method. The method comprises the following steps of: 1, determining reliability design knowledge data acquisition principles, and describing the reliability design knowledge acquisition principles by using a feature vector representation method; 2, pre-processing knowledge data by using the reliability design knowledge acquisition principles, and standardizing the identified identification features; 3, performing integrity verification and redundancy verification on the pre-processed reliability design knowledge data, and storing the audited data in a knowledge base; and 4, automatically extracting initial reliability design criteria from the reliability design by using a program, then judging the reliability design criteria by a manual judgment method, and storing the reliability design criteria passing the judgment in a criteria base.

Description

Technical field [0001] The invention provides a knowledge collection template and a criterion extraction method for product reliability design, which relates to a knowledge collection template, which can be used to standardize reliability design related data, and form a knowledge base according to the data format of the template, At the same time, a method for extracting reliability design criteria from the knowledge base is given. It belongs to the technical field of system reliability. Background technique [0002] The development of complex products often has great inheritance. Therefore, the design data accumulated by the company for many years and the design experience of designers are summarized and refined to form reliability design guidelines. For inheriting previous reliability design experience and implementing standardized reliability It is of great engineering practical value to effectively improve the reliability design level of products. [0003] At present, ...
