产品设计过程中质量知识的匹配方法

提出了一种产品设计过程中基于语义距离的设计质量知识的表示及匹配方法,将产品设计过程划分为5个阶段,构建产品设计质量信息模型。依照设计质量信息模型,对设计任务、设计人员和设计质量信息进行分析,以任务元、对象元、信息元来构建三者的形式化描述体系,并建立其数据结构。利用HNC(概念层次网络)知识库,基于语境框架文本相似度计算,并结合语义距离计算,实现了文本间相似度的精确量化和比较。以注塑机方案设计过程为例,实现了设计质量信息匹配,验证了该方法的有效性。

Matching Method for Quality Knowledge in Product Designing Process

The design quality information and matching method based on semantic distance was presented in product designing process. Product design process was divided into five phases, and then the model of product design quality information was built. According to the model, the design task, designer and design quality information were analyzed. The task meta, object meta and information meta were described and the data structure was built. Using hierarchical network of concepts (HNC) and combining with semantic distance calculation, the quantification and comparing of text similarity can be realized based on framework of context text similarity. Finally, the conceptual design of injection molding machine was taken as an example, the result showed the effectiveness of the proposed method.
