【摘要】 当前,社会活动频繁,人们消费增长,导致环境负荷不断增长,污染日益严重。产品服务系统作为一种实现经济可持续发展的方法而产生。它将企业的价值链向后端的服务环节延伸,通过增值服务使产品在减小资源消耗和环境影响的条件下尽可能地发挥社会效益。MRO是在产品生命中期阶段所进行的各种维护、维修、大修和运行等服务活动的总称,需要完整体系的技术进行支撑。本文结合浙江省重点优先主题项目“现代制造服务关键技术研究与应用”,对复杂装备MRO服务中的若干关键技术进行了深入研究,并以汽轮机制造企业为应用对象,验证了技术的研究成果,开发出了完整的MRO服务管理信息系统。第一章阐述了产品服务系统的研究背景,指出了对产品服务系统及其MRO服务进行研究的意义,并回顾和分析了国内外相关领域的研究状况。在此基础上,提出本文的研究内容和结构。第二章分析了MRO服务的概念、在产品生命周期中的地位和作用以及服务的主要业务内容,并系统地研究了MRO的体系结构、集成模型和支持技术体系,指出其中的关键技术,为后续研究指明方向和重点。第三章详述了复杂装备MRO服务中远程故障诊断技术的内涵、内容、作用及需求,并根据MRO服务特点建立了远程故障诊断系统的结构和业务模型,提出了基于产品型号管理监测配置和基于振动信号分析进行故障诊断的方法。第四章建立了派工调度中业务对象和业务流程的模型,并根据派工的原则和方法,结合遗传算法和评价方法,建立多目标决策模型,智能选派最佳的人员团队去执行MRO任务。最后进行了模拟试验,验证了算法的可行性。第五章研究了GIS的特点和实现技术,并将其应用于MRO对象定位和信息跟踪管理中,为企业MRO信息管理提供了一种更加直观清晰的方式。第六章将上述理论和技术方法系统地应用于汽轮机制造企业,详述了复杂装备MRO服务管理系统的设计思想、功能模块及开发过程,验证了技术的应用。第七章总结了论文的研究工作和创新点,并对后续的研究工作进行了展望。更多还原

【Abstract】 Nowadays, as social activities became more frequent and people’s consumption grew rapidly, consequently environmental load increased continuously and pollution was worse and worse. Thus, as a methodology of achieving sustainable economy, Product-Service System (PSS) emerged, and extended enterprise value chain to service sectors in the back-end. In the condition of reducing resource consumption and environmental impact, value-added services made the products to realize social benefits as much as possible. Being in the middle stage of PSS and related product lifecycle, MRO is a general term of various services activities, i.e., all kinds of maintenance, repair, major repair, and operation, in this stage. Without sufficient theoretical and pragmatic support, MRO should be backed by integral technology framework. Based on Zhejiang Province High-Tech Prime Program entitled "Research and Application of Key Technologies for Modern Manufacturing Service", this thesis studied in-depth several key technologies of MRO services of complex equipment. Hangzhou steam Turbine Company (HTC), as a case study, was studied to validate research achievement of related technologies. A whole MRO services management information system was also developed.Chapter 1 introduced the background of Product-Service System (PSS) and indicated the importance of studying PSS and related MRO services. Domestic and international research status quo in the related areas was also reviewed and analyzed. As a result, research content and structure of this thesis was given.Chapter 2 analyzed the issues of MRO services, i.e., the concept, the position and function in the product lifecycle, and the main business content. The system architecture, integrating model, and support technology system were also systematically studied. The key technologies were pointed out to indicate the direction and highlights of subsequent research.Chapter 3 described in detail distant fault diagnosis technology in the MRO services of complex equipment, and its related connotation, content, function, and requirements. Structure and business models of distant fault diagnosis system were established according to the features of MRO services. Two methods of diagnosing faults were proposed. One based on product model number management detection configuration; the other one based on vibration signal analysis.Chapter 4 developed the models of business objects and business processes in the service staff scheduling. Based on scheduling rules, multi-objective decision model was established. Improved genetic algorithm and related evaluation methods are utilized to intelligently select the most appropriate service staff team to execute MRO tasks. Simulation experiment and related programs were developed to validate the feasibility of this decision model and algorithm.Chapter 5 studied the features and realization technologies of Geographic Information System (GIS), which was applied to position and track MRO objects. It provided a vivid and clear way for enterprises in MRO information management.Chapter 6 applied the theories and technologies methodologies above at Hangzhou steam Turbine Company (HTC) and described at length the design thoughts, function modules, and development procedure of MRO services management system for complex equipment. System performance was presented to verify the application of the technologies above.Chapter 7 summarized research work and innovations of this thesis and gave a prospect for future studies.更多还原
