基于关联规则的MBD数据集定义研究与实现

针对产品全三维数字化研制需求,提出了一种基于关联规则的基于模型定义(MBD)数据集定义方法.首先,对产品研制过程中所有设计、制造和检验的标准进行细化分解,并对所有这些标准的工作方法、指令、要求即工程注释项进行统一编码,并由计算机管理和发布;其次,对MBD数据集创建过程的历史记录进行关联规则挖掘,发现工程注释项间潜在的关联关系;最终,根据工程注释项间关联关系,实现MBD创建过程中相关工程注释项的推荐.该方法以数据挖掘中关联规则理论为基础,从MBD数据集构建历史数据中获取有用的知识和经验,通过相关工程注释项推荐,进而提高MBD数据集创建效率.

Research and implementation of MBD dataset definition based on association rules

A model based definition (MBD) dataset definition method based on the association rules was proposed to meet the requirement of product full three dimensional digitalization development. Firstly, this method thoroughly decomposed all the design, manufacturing and inspection standards used in the product's development process. All the standard operation method, order and requirement (engineering note items) of all the standards were uniformly encoded, managed and released by the computer. Secondly, the association rule was utilized to mine the MBD dataset's creation history records, by which the potential association relationships among engineering note items can be revealed. Finally, based on the association relationships among engineering note items, the proper engineering note items can be pushed out as needed in the process of MBD creation. The proposed method uses the association rule theory in data mining as its basis, exploiting the helpful knowledge and experiences obtained from MBD dataset's creation history, thus is capable of improving the MBD dataset's creation efficiency by engineering note items recommendation.
