【摘要】 在企业信息化进程中,为了提高企业的竞争力,企业先后兴建了各种各样的应用系统,各应用系统彼此孤立,不能实现信息共享,形成的“信息孤岛”引起了企业越来越多的关注,目前企业对EAI(企业应用集成)的需求相当迫切。本文以国家高技术研究发展计划资助项目“基于本体的面向业务协作的异构系统集成技术研究及应用”(2006AA042157)和浙江省自然科学基金项目“面向业务协作的异构系统语义集成技术研究和应用”(Y107360)为依托,以企业间业务协作为研究对象,在现有的异构系统集成技术的基础上,研究并实现了基于本体的企业间异构系统集成技术。论文的主要内容如下:第一章绪论。首先介绍了课题研究的背景和研究意义,综述了课题的国内外相关研究现状,并指出目前的异构系统集成方法在制造企业中应用时所遇到的障碍。然后,阐述了本课题的研究内容,最后介绍了论文的结构。第二章研究了基于本体的企业间业务协作的机制,提出了业务协作异构问题模型,并介绍了相关解决技术。在此基础上,提出了异构系统语义集成的理论框架,介绍了理论框架的层次划分以及各个层次的作用。第三章研究了业务协作领域本体和企业局部本体的构建方法。在本章节中,着重讨论如何将企业的知识构建成本体,为实现企业间的语义互操作奠定基础。第四章研究了基于本体的企业间异构系统互操作机制的实现。分析了实现语义互操作涉及的关键技术,重点研究了通过本体映射解决语义异构的方法。同时,讨论了在本体映射基础上的语义转换机制。第五章介绍了基于本体的异构系统集成平台的实施。说明了集成平台的开发环境和运行原理,以及平台总体功能模型和各功能模块的实现。第六章总结部分。对全文的工作进行总结,并对下一步的工作进行了展望。更多还原

【Abstract】 In the process of enterprise informatization, in order to improve the competitiveness, enterpriseshave built a wide variety of applications. However, these applications are isolated from eachother, and can’t achieve information sharing. The formation of "information islands" has drawnincreasingly attention of enterprises. With the support from the National High-Tech. R&DProgram of China (No. 2006AA04Z157) and Zhejiang Natural Science Foundation (No.Y107360), this paper take business cooperation as object, based on the existing heterogeneoussystems integration technologies, researched and implemented ontology-based inter-enterpriseheterogeneous systems integration. Main contents including:Chapter I introduced the background and significance of our research, and overviewed theresearch status of related topics. Then, the content and architecture of this thesis was discussed.Chapter II studied the ontology-based mechanism for inter-enterprise business collaboration,and proposed the heterogeneous problem model. Based on this, a heterogeneous systemsintegration framework was put forward.Chapter III studied the construct methodology of business collaboration domain and enterpriselocal ontologies. In this section, we focused on how to build ontologies for semantic integrationof business processes, which lays the foundation for achieving semantic interoperabilitybetween enterprises.Chapter IV studied the ontology-based interoperability mechanism among enterpriseheterogeneous systems. In this chapter, we analyzed key technologies related to achievesemantic interoperability, and focused on resolving semantic conflicts through ontologymapping. Meanwhile, the semantics conversion mechanism based on ontology mapping wasdiscussed.Chapter V described the implementation of ontology-based integration platform forheterogeneous systems. We illustrated the operating principles and functional model of theplatform, as well as the implementation of each functional module.Chapter VI summarizes the whole thesis and forecasts further research directions.更多还原
