【摘要】：复杂产品设计是典型的知识密集型工作,伴随市场竞争全球化,劳动力成本日益提高,资源环境约束不断增强,企业难以对市场做出快速响应。本文为了提高企业快速设计能力,对复杂产品设计知识重用展开了研究,并以摊铺机为例,设计并开发了知识重用原型系统。首先,通过分析复杂产品对知识管理的需求,采用了基于本体的产品设计建模方法,以摊铺机为例,完成了摊铺机产品领域知识的获取与建模,并进行了形式化表示。其次,建立了面向设计知识重用的知识服务系统框架,通过研究产品全生命周期理论、产品结构树理论、专家知识地图理论,分别建立设计过程库、物理结构库、专家库,实现了知识的情景化、脉络化。然后,研究了知识在知识重用系统中的流动性,并提出了与知识重用系统相结合的知识管理与创新机制。最后,设计出摊铺机设计知识重用原型系统,实现了摊铺机设计知识的管理,促进了产品的快速设计,验证了本文的研究成果。
[Abstract]:Complex product design is a typical knowledge-intensive work. With the globalization of market competition, labor costs are increasing day by day, and resource and environment constraints are constantly strengthened. In order to improve the enterprise's ability of rapid design, this paper studies the knowledge reuse of complex product design, and takes paver as an example, designs and develops a prototype system of knowledge reuse. By analyzing the demand of complex products for knowledge management, the method of product design modeling based on ontology is adopted. Taking paver as an example, the acquisition and modeling of knowledge in paver product domain are completed, and the formal representation is given. The framework of knowledge service system for design knowledge reuse is established. Through the research of product life cycle theory, product structure tree theory and expert knowledge map theory, the design process database, physical structure database and expert database are established, respectively. Then, the fluidity of knowledge in knowledge reuse system is studied, and the knowledge management and innovation mechanism combined with knowledge reuse system is proposed. A prototype system of paver design knowledge reuse is designed, which realizes the management of paver design knowledge, promotes the rapid design of products, and verifies the research results of this paper.
