【摘要】 目前大多数产品信息语义描述研究都集中在结构方面,忽略了对行为的表达。为了支持复杂产品数字化协同设计,满足各个部门进行知识级的信息交换和共享,本文提出建立一个基于静态结构和动态行为的"产品共享信息语义模型"的统一描述框架。基于上述模型,采用本体描述语言OWL来描述产品的静态结构信息,给出了定义、组织及描述产品共享和通用的知识的方法;借鉴面向服务的思想,提出用语义网服务标记语言OWL-S描述产品的动态行为信息,并给出了表达交互的方法。以面向导弹战斗部的数字化设计为例,初步实现了基于共享信息模型框架的战斗部结构和行为语义描述。OWL和OWL-S的应用,有利于复杂产品数字化设计过程中知识的共享和重用。更多还原

【Abstract】 At present,most of research focuses on semantic descriptions for the structures of products,while ignoring dynamic behavior descriptions.In order to support collaborative digital design of complex products and to meet the needs of knowledge exchange and sharing among departments,we propose a uniform description framework of "product shared information semantic model" based on the static structure and dynamic behavior of a product.On the basis of the model,we introduce a new approach to describe product knowledge.On the one hand,we give a method to define,organize and describe the shared and common knowledge of product structure with OWL;on the other hand,behaviors are abstracted as services,so that OWL-S can be adopted to describe the dynamic product behavior information.A method is proposed to conduct the transformation.Taking the digital design of a missile warhead as an example,we have initially realized the semantic descriptions of the structure and behaviors of the warhead based on the shared information semantic model framework proposed in this paper.The example shows that the application of OWL and OWL-S can significantly benefit knowledge sharing and reuse in the process of digital design of complex products.更多还原
