摘 要: 为了有效支持产品变型设计和大批量定制设计,将产品平台中的广义模块按不同属性分成6类,针对分类得到的参数化模型进行包含性关系挖掘。对参数化模型间的包含性关系分析主要包括4个步骤:1) 从广义模块中抽取各类代码作为数据表的字段,将各类零部件的序号作为数据表的事务,构建事务数据表;2) 将事物数据表转化为0-1矩阵,运用Apriori算法找出频繁项集;3) 通过比较频繁k-项集内部的置信度,得到参数化模型之间的强关联关系;4) 得到模型间包含性关系。最后以阀门产品为例,对提出的包含性分析方法进行验证,并输出阀门各个参数化模型间的包含性关系。研究结果表明:经挖掘得到的包含性关系有利于产品与工艺资源的快速检索和再利用,便于产品与工艺的精确和非精确配置,进而促进企业大批量定制产品战略的有效实施。

Abstract:In order to effectively support the product variant design and the mass customization design, the generalized modules in the product platform were divided into six parameterized models based on different attributes, mining inclusive relationship among these parameterized models. The inclusive relationship analysis mainly includes four steps: 1) Various types of codes were extracted from generalized modules as the code segments, and the serial number of components was used as the transaction to construct the transaction data table; 2) The transaction data table was converted to 0-1 matrix and the frequent item sets was obtained by the Apriori algorithm; 3) The confidence scores in the frequent k-item sets were compared to get the strong relationships; 4) The relationship among the parameterized models was obtained. Finally, the feasibility and effectiveness of the proposed method were verified by a case study of valve. The results show that the inclusive relationship analysis is conducive to rapidly reuse products and process resources, to facilitate the accurate and inaccurate product and process configuration, and to promote the effective implementation of enterprise mass customization strategy.
