概念设计中基于知识流的多维设计知识统一建模技术研究

Unified Multidimensional Model Based on Knowledge Flow in Conceptual Design

[目的]为实现概念设计知识的有效管理和重用,研究概念设计中的多维设计知识统一建模技术。[方法]从知识管理和知识重用两个方面分析多维设计知识的统一建模需求;基于知识流理论,从设计过程和知识属性两个角度对概念设计知识进行分类和定义;以静态设计对象和动态设计流程为核心,构建多维设计知识统一建模体系;借助本体模型实现概念设计中多维设计知识的统一建模。[结果]将概念设计知识分为设计对象、设计流程、设计组织、设计资源、设计准则、设计案例6类;以设计对象和设计流程为核心,提出对象–流程双核知识驱动的多维设计知识统一建模体系;构建对象–流程双核知识本体模型,进而对设计组织、设计资源、设计准则、设计案例4类知识进行建模和组织。[局限]未对统一建模技术进行进一步验证。[结论]所提出的统一建模技术能够从动态性角度对概念设计知识进行全面、有效的建模。

[Objective] This paper studies the unified modeling technology for multidimensional design knowledge in conceptual design, aiming to effectively manage and reuse knowledge. [Methods] First, we analyzed the needs of unified modeling for multidimensional design from the perspectives of knowledge management and reuse. Then, we classified the conceptual design knowledge based on design process and knowledge attributes. Third, we constructed the unified model system for multidimensional design knowledge with static design object and dynamic design flow at the core. Finally, we established the unified model with the help of Ontology model. [Results] We divided the conceptual design knowledge into six categories： design objects, design flow, design organization, design resources, design criteria and design cases. We proposed a unified modeling system based on design object and flow, and also created the knowledge Ontology to model the knowledge of design organization, design resources, design criteria and design cases. [Limitations] More research is needed to examine the proposed technology. [Conclusions] The unified modeling technology enables us to effectively model the dynamic conceptual design knowledge.
