Embodiment Construction

[0062] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention. in, image 3 Among them, 1 is the physical space primary selection, 2 is the logical space comparison, and 3 is the attribute space comparison.

[0063] The primary selection of product information in the present invention is realized by querying the physical space, the physical space is used to store the metadata of the logical space and the attribute space, and the metadata is used to describe the data, indicating the storage location, resource search, file record and other information . Logical space refers to the logical relationship between product compo...

Abstract

The invention discloses a PLM (product life-cycle management) database-based multi-spatial data product families mining algorithm. According to the method of the invention, with a product structure tree (PST) or a bill of material (BOM) in a PLM (product life-cycle management) database adopted as a data source, based on the utilization of information comparison of the physical space, logic space and attribute space of product data, analysis and extraction of the product families can be realized. The method is characterized in that: a product main feature vector comparison-based algorithm is utilized; clustering analysis is performed on the output results of the algorithm; and a threshold value is set for a clustering result; and a final product family classification scheme can be obtained. The algorithm of the invention has the advantages of convenience in calculation, high operability and wide application range, and can classify the product families more accurately and rapidly. With the technical schemes of the invention adopted, a more scientific method can be put forward based on a DPIPP. With the algorithm of the invention adopted, cost in the implementation process of MC (mass customization) can be reduced. The algorithm is of great significance for the MC.

Description

technical field [0001] The present invention belongs to the construction of a product platform technology, especially involving a PLM -based database -based database -to -DPIPP (distributed parameterized smart product platform) product family mining algorithm. Background technique [0002] With the gradual popularization of the product of product full life cycle management (PLM) technology (PLM) technology, enterprise product data has increased in advanced numbers. The data of these product data contains advanced management ideas and contains a lot of products and process knowledge. How to manage and use these product data scientifically is the key to reducing corporate costs. In a large number of customized environments, in order to meet the diversity of customers, the varieties of products need to be continuously increased. The Bill of Material (BOM) structure of different products in these series of products has similarity and contains a large amount of the same parts. ...
