【摘要】：随着信息技术的发展,以工艺知识为支撑的分布式协同开发方式,逐渐成为主要的军工产品研制方式,工艺知识成为军工制造发展和创新的核心竞争力。以知识库系统为工具平台,实现工艺知识的共享和重用,消除各军工制造系统之间的资源孤岛和重复建设,是当前军工制造领域的一个重要研究方向。本文以军工制造相关工艺技术为对象,构建了军工工艺知识体系和相应的知识库,研究了高效的知识检索方法,并开发了知识管理与应用的软件系统,促进了军工工艺知识的共享和重用。首先,本文在分析了军工工艺管理现状及知识库系统相关研究现状的基础上,对军工工艺知识库系统进行了需求分析,基于需求分析构建了系统的框架结构和功能结构。然后,本文面向12大军工制造工艺技术领域,组织并构建了军工工艺知识体系,在此基础上,研究并构建了基于本体的军工工艺知识库,并实现了军工工艺知识本体的持久化存储。针对实际应用需求,研究并提出了一种基于本体语义扩展和用户属性协同过滤的混合知识检索机制,并通过实验验证了算法的有效性和准确性。最后,根据软件工程的思想,设计并开发了 "军工工艺技术体系知识库系统",并在军工制造相关厂、所进行了实际部署和应用。通过上述研究工作,实现了工艺知识的个性化准确检索,提高了工艺知识的获取效率,加速了工艺知识在不同系统之间的转移,提高了工艺知识的共享和重用水平。
[Abstract]:With the development of information technology, distributed cooperative development supported by technological knowledge has gradually become the main way to develop military products, and process knowledge has become the core competitiveness of military manufacturing development and innovation. Taking the knowledge base system as the tool platform to realize the sharing and reuse of process knowledge and to eliminate the resource isolation and repeated construction among the military manufacturing systems is an important research direction in the field of military manufacturing at present. In this paper, the knowledge system and knowledge base of military manufacturing are constructed, the efficient knowledge retrieval method is studied, and the software system of knowledge management and application is developed. It promotes the sharing and reuse of military process knowledge. Firstly, based on the analysis of the current situation of the military process management and the research status of the knowledge base system, the requirement analysis of the military process knowledge base system is carried out. Based on the requirement analysis, the frame structure and function structure of the system are constructed. Then, the knowledge system of military manufacturing technology is organized and constructed in this paper, which is oriented to 12 major military manufacturing technology fields. On this basis, the knowledge base of military process based on ontology is studied and constructed. The persistence storage of military process knowledge ontology is realized. A hybrid knowledge retrieval mechanism based on ontology semantic extension and user attribute collaborative filtering is proposed to meet the practical application requirements. The validity and accuracy of the algorithm are verified by experiments. Finally, according to the idea of software engineering, the knowledge base system of military process technology system is designed and developed, and the actual deployment and application are carried out in the military manufacturing plants. Through the above research work, the personalized and accurate retrieval of process knowledge is realized, the efficiency of process knowledge acquisition is improved, the transfer of process knowledge between different systems is accelerated, and the level of sharing and reuse of process knowledge is improved.
