【摘要】 PDM中产品描述的柔性有助于PDM在不同企业中实施,而产品属性的客户化定制是产品描述柔性的体现。提出了映射和使用XML技术等两种实现产品属性的客户化定制的方法。映射方法是在属性数据字典中动态地记录产品属性的定义,同时建立指向属性内容表对应表列的指针;使用XML的方法则将属性数据按XML格式存储到一个字段中。在分析这两种方法的优缺点后,采用映射的方法进行数据库设计和系统框架设计,在国内某机床企业实施的PDM中验证了该方法的可行性。更多还原

【Abstract】 The flexibility of product description is helpful to implement PDM systems in different enterprises, and cus2 tomization of the product attributes can enhance the flexibility. Mappingmethod and XMLsegment method are proposed in this paper to realize the customization of product attributes. Advantages and disadvantages of these two methods are discussed. Mapping method is adopted for further database and system design in the imple2 mentation of a PDMsystem in a Chinese machine tools factory. The feasibility of this method is proven in the case study.更多还原
