基于可配置模板的产品设计知识多维度表达方法

Multi-Dimensional Representation for Product Design Knowledge Based on Configurable Knowledge Template

为解决产品设计知识多维度分类体系中的知识表达问题,研究了可配置模板的构建技术,实现了基于可配置模板的产品设计知识多维度表达.首先,在考虑设计知识动态演化特性的前提下,给出了可配置模板的定义,然后建立了包括模板构建流程、模板实例化在内的可配置知识模板构建方法.通过支持自定义的树结构,构建了设计知识多维度视图模型.多维度视图模型通过引用模板,使得根据不同模板实例化的知识关联到对应的视图节点之下,实现了产品设计知识的多维度表达.基于该方法开发的软件系统在航天、船舶等企业进行了应用,验证了该方法的可行性和有效性.

A configurable template base method was proposed to solve the problem in multi- dimensional representation of product design knowledge. Firstly, considering the dynamic evolution of design knowledge, the definition of configurable knowledge template was presented. Then, the construction process of configurable knowledge template was described, including template building process and template instantiation. Then a multi-dimensional knowledge representation model was created through a customizable tree structure in which knowledge template was cited, and thus the template instances were clustered to the referenced node. A software system based on this method is applied in several enterprises in aerospace and shipbuilding industries. The feasibility and effectiveness of this method is validated.
