面向产品设计的知识主动推送研究

Knowledge active push for product design

分析了基于知识的产品设计,针对现有系统不能主动将知识在适当的时候传递到适当设计人员的缺点,提出了一种基于知识管理的、以工作流驱动的、产品设计的知识主动推送体系结构,分析了其主要层次结构及知识的组织和管理,提出了以工作流驱动的知识主动推送方式。建立了知识主动推送的控制模型,根据知识主动匹配算法分析了设计任务、设计子任务、设计人员、设计知识及其数据结构;将基于语境框架的文本相似度计算延伸到设计领域,提出了基于设计对象的文本相似度计算方法;通过相似度计算对设计人员匹配适当的知识,开发了知识管理和工作流的集成原型系统,并以电涡流缓速器设计为例实现了知识的主动推送。

Knowledge--based product design was analyzed. Aiming at the shortage that the knowledge can not be pushed actively to the proper designer at the proper time, a knowledge active push framework based on knowledge management and driven by workflow was proposed and the main layers were analyzed. At the same time, the organization and management of knowledge were discussed. A novel knowledge active push method driven by workflow was presented, and the control model built for active push of knowledge was given. The design task, design subtask, designer and design knowledge were analyzed, and their data structures were established. Text similarity computation based on context framework model was extended to product design field. A text similarity computing method based on design object was proposed and used to match proper knowledge for the designer. Finally, a prototype system, which was integrated through knowledge management and workflow, was developed and an example of eddy current retarder design was given to realize the active push of knowledge.
