面向快速响应设计的零件资源可重用建模与匹配

Parts resource reusable modeling and matching for rapid response design

针对产品快速响应设计中零件资源的可重用需求,建立了扩展PLIB(ISO 13584)标准的通用零件模型.该模型通过基于PLIB标准元模型的描述层,实现了零件资源一致性的语义描述;通过引入操作层,实现了零件资源在具体应用环境中的功能扩展,并给出了零件资源面向对象的零件族分类组织结构.针对面向对象资源检索中需求域不明确的问题,通过相似性匹配度并结合零件族分类位置权重,给出了覆盖需求域的零件族逐步定位算法,优化了零件资源检索的过程.该方法在一个面向快速响应设计的Web零件资源共享平台上得到了有效的应用.

Rapid response design requires parts resource reusable as much as possible. A general parts information model was built by extending PLIB （ISO 13584） standard. In the information model, the semantic consistency of parts resource was ensured by the description layer based on PLIB standard metadata model. Moreover, functional extending for parts resource under application environment was realized by introducing operation layer. A hierarchical organization for object-oriented parts family was built by referencing the international classification of standards. In order to solve the requirement object＇s implicit problem in the object-oriented resource information retrieval, a stepwise searching algorithm to match the bestsuited requirement object was presented considering the location weight of parts family in the hierarchical organization, which optimized the retrieval process of parts resource. Finally, the presented methods were effectively applied to build a web-based parts resource sharing platform for rapid response design.
