【摘要】：随着国际化市场竞争的日益激烈,以及信息技术的进步,经济全球化的竞争环境逐步形成,市场需求瞬息万变,产品个性化需求不断多样化、产品制造周期不断缩短、技术含量不断增大,制造企业仅依靠自身内部的信息集成和设备柔性化等措施已经很难有效改善企业整体敏捷性,迫切需要通过企业间的强强合作来提高自己的综合竞争能力,进而实现多赢。云制造正是在这一背景下产生的。云制造是企业为应对知识经济和制造全球化的挑战而实施的以快速响应市场需求和提高企业竞争力为主要目标的一种先进制造模式。通过采用先进的计算机技术、网络技术、通信技术、人工智能技术、云计算技术、制造技术及其它相关技术,构建面向企业特定需求的基于网络的制造系统,突破空间地域对企业生产经营范围和方式的约束,实现企业间的协同和各种社会资源的共享与集成,高速度、高质量、低成本地为市场提供所需的产品和服务。在新的制造模式下,传统的技术服务模式已无法满足企业和用户的需要。网络化协同技术服务是指通过Internet和Web技术,通过企业间的协同合作,为客户提供所需要的服务知识和信息,它是在产品和客户分散化、全球化背景下制造企业实现对客户服务的一种新模式。网络化协同技术服务系统是为了适应企业制造的分散化以及客户和设备供应商的国际化需求而提出的一种新思路,它主要是采用系统工程的理论、技术和方法,借助于网络技术、计算机技术、现代通信技术、人工智能技术和多媒体技术等建立的用于支持企业内部、企业与客户和供应商之间的信息交换、知识共享和协同工作的计算机网络系统。本文首先综述了国内外云制造技术与技术服务的现状与发展趋势,阐明了本文研究的目的、意义及主要研究内容。在此基础上,对面向云制造的网络化协同技术服务的体系结构、面向云制造的虚拟企业合作伙伴选择、面向云制造的制造信息采集与融合方法、网络化技术服务的知识融合与重用、面向云制造的网络化协同技术服务任务指派与列队进行了深入的研究并在理论研究的基础上进行了原型系统开发。本论文的主要研究工作有：(1)在查阅了国内外大量文献资料的基础上,对云制造的内涵与特征、主要研究内容、国内外研究现状与发展趋势及技术服务的定义、国内外研究现状与发展趋势进行了全面的综述,阐明了研究的重要性与意义。(2)分析了面向云制造的网络化协同技术服务系统的功能需求,建立了面向云制造的网络化协同技术服务系统的功能模型,设计了基于Multi-agent面向云制造的网络化协同技术服务系统的系统结构。(3)建立了面向云制造的虚拟企业合作伙伴选择综合评价指标体系,采用模糊综合评价法对合作伙伴进行精选,运用遗传算法对合作伙伴进行优化组合并对所建立的优化算法进行了实例分析。(4)研究了RFID与条码技术相结合的制造数据采集方法,建立了一种分布式管理集中存储的信息采集模型,提出了在感知层和数据层设置感知代理的思路,从理论上对智能采集模型进行了分析和评价。(5)为了提高系统的智能化,进而提高技术服务的效率和质量,研究了基于本体论的技术服务知识融合与重用,构建了面向云制造的网络化协同技术服务知识融合的体系结构,研究了技术服务领域知识本体库构建方法。(6)研究了云制造模式下网络化协同技术服务任务指派流程、分类与分配方法,建立了基于匈牙利算法的技术服务列队排序模型与任务指派的模型,并进行了实例验算。(7)在理论研究的基础上结合沈阳某企业的实际需求进行了面向云制造的协同技术服务原型系统开发,并对系统部分功能模块的实现与使用方法进行了简单分析。系统的试运行结果验证了理论研究的正确性与技术的可行性。
[Abstract]:With the internationalization of the increasingly fierce market competition, and the progress of information technology, economic globalization gradually formed, changing market demand, personalized products demand diversification, product manufacturing cycle shortened, the technical content is increasing, manufacturing enterprises only rely on their own internal information integration and flexible equipment and other measures have been difficult to improve the whole enterprise agility, the urgent need to improve their overall competitiveness through strong cooperation between enterprises, and achieve win-win. Cloud manufacturing is generated in this background. Cloud manufacturing is an advanced manufacturing mode of enterprise and to respond to the globalization of knowledge economy and manufacturing challenges with the rapid response to market demand and to improve the competitiveness of enterprises as the main target. Through the use of advanced computer technology, network technology, communication technology, artificial intelligence technology, The cloud computing technology, manufacturing technology and other related technologies, the construction of manufacturing system based on network for the specific needs of enterprises, break through the geographical space constraints on business scope and mode, to achieve inter enterprise collaboration and social resources sharing and integration, high speed, high quality, low cost to provide the required products and services for the market. In the new manufacturing mode, the traditional model of technical services has been unable to meet the needs of enterprises and users. The network collaborative technical service refers to the Internet and Web technology, through the collaboration between enterprises, to provide knowledge and information services for the needs of customers, it is in the product and the customer decentralization of manufacturing enterprises under the background of globalization, a new model of customer service. The network collaborative technical service system is to adapt to the enterprise manufacturing and equipment supplier and customer diversification A new idea of international demand, it is mainly the use of system engineering theory, technology and method, by means of network technology, computer technology, modern communication technology, artificial intelligence technology and multimedia technology to establish the support for the enterprise, between enterprises and customers and suppliers of information exchange, knowledge of computer network system sharing and collaborative work. This paper reviews the current situation and development trend of domestic and foreign cloud manufacturing technology and technical service, expounds the purpose of this study, the main research contents and significance. Based on the architecture of networked collaborative manufacturing technology services across Xiang Yun, virtual enterprise oriented cloud manufacturing partner selection method for manufacturing information collection and integration of cloud manufacturing, network knowledge integration and reuse of technical services, network oriented cloud Manufacturing Technology Service Co The task assignment and lined up and in-depth study of the prototype system developed on the basis of theoretical research. The main research work of this thesis are: (1) based on a large amount of literature at home and abroad, the connotation and characteristics of cloud manufacturing, the main research content, defines the research status and development trends and technical services, the status quo and development trend of research at home and abroad were reviewed, expounds the importance and significance of the study. (2) the analysis of functional requirements for the networked manufacturing collaborative cloud technology service system, set up the function model for the networked manufacturing collaborative cloud technology service system, design the structure of the Multi-agent system for the networked manufacturing collaborative cloud technology service system based on. (3) established a virtual enterprise oriented cloud manufacturing partner selection based on fuzzy comprehensive evaluation index system. Selection of partners in the comprehensive evaluation method, using genetic algorithm to optimize the combination of partners and the optimization algorithm is established through a case study. (4) studied the manufacturing data of RFID and barcode technology combined with the acquisition method, establishes a set of distributed storage management information collection model, put forward in the the perception layer and data layer sensing agent ideas, analyzes and evaluates the intelligent acquisition model in theory. (5) in order to improve the intelligence of the system, and improve the efficiency and quality of technical services, technical services of knowledge integration and reuse based on ontology, constructs the architecture of collaborative technical service knowledge the fusion of network oriented cloud manufacturing, technical services of domain knowledge ontology construction method. (6) research on the cloud manufacturing mode of networked collaborative technical service task assignment process, Classification and distribution method, set up technical service based on Hungary algorithm queue scheduling model and task assignment model, and the example is calculated. (7) according to the actual needs of an enterprise in Shenyang, based on the theory study of cooperative development technology for manufacturing cloud service prototype system, and the realization of system function module with the use of methods is briefly analyzed. Test results verify the system correctness and feasibility of the theoretical research.
