【摘要】 我国已成为世界加工制造大国。跨企业、跨区域甚至跨国界的协作型加工制造业正迅速发展并已成为我国制造业的重要组成部分之一。协作型加工制造业是由“主导企业”(主机厂或委托厂等)下定单、图纸和技术要求,“协作加工企业”进行加工制造的一种量大面广的产业模式。随着经济全球化和信息网络的飞速发展,网络化制造模式已逐渐成为现代制造企业的重要发展趋势之一。在网络化制造系统的支持下,主导企业进行协作加工资源选择的范围已不再局限于某几个企业和某几个区域,而是逐渐发展成为一种全球性的、网络化的优化利用模式。如何支持企业更广范围的优化配置协作加工资源,以及如何更有效的提升协作企业间的信息交互和业务协作能力,是当前网络化协作加工领域研究和应用的热点问题之一。论文在借鉴国内外已有研究成果的基础上,围绕网络化协作加工资源的优化配置方法及其加工支持系统进行了一些探索和研究。首先,在分析网络化协作加工资源的构成属性及特点的基础上,对网络化协作加工资源语义描述及集成服务机制进行了研究,包括:研究了网络化协作加工资源的本体建模及语义描述方法;提出了一种基于扩展的统一描述、发现和集成协议(Universal Description Discovery and Integration,UDDI)的网络化协作加工资源注册发布机制和基于语法级与语义级相结合的搜索匹配算法;在此基础上,建立了一种能促进资源快速共享和高效利用的网络化协作加工资源集成服务运行模式。其次,针对网络化协作加工资源选择的影响因素,提出了包含协作响应速度(T)、协作质量(Q)、协作成本(C)、协作信息交互能力(I)、协作过程技术安全和保密性(S)、协作资源保障能力(R)和协作商知识积累及可持续发展能力(K)等七大目标变量的决策目标体系,建立了一种网络化协作加工资源优化选择的决策框架模型,针对决策过程中信息的隐蔽性、模糊性等特点设计了模型求解的灰色关联算法,并通过应用实例,验证了上述模型及方法的正确性和实用性。再次,针对协作加工资源优化配置过程中的多任务性、多候选资源性、多目标性和环境多变性等特点,采用线性加权法建立了以协作加工时间(T)、协作加工成本(C)和协作加工质量(Q)等为目标的多任务协作加工资源优化配置模型,设计了基于遗传算法的求解过程,并以一个应用实例验证了该优化配置模型及求解方法的有效性与实用性。然后,针对网络化协作加工过程的信息交互和业务协作的需求,设计了一套基于网络化多功能交互式信息终端的网络化协作加工支持系统,构建了该系统的体系结构、功能结构和运行模式;并对基于网络化多功能交互式信息终端的协作加工过程实时信息采集、协作任务可制造性协同分析、数控程序协同编制等协作加工过程信息交互与业务协作支持技术,以及系统的部分实现关键技术进行了研究。最后,结合重庆市网状中心城市型区域网络化制造系统的实施,针对摩托车零部件制造业的现状和需求,设计和开发了一套摩托车零部件制造企业网络化协作加工运行支持系统,并在重庆市一摩托车零部件制造企业进行了应用,取得了良好应用效果。

【Abstract】 Our country has become one of the major manufacturing countries in the world. The collaborative processing manufacturing industry which is cross-enterprise, cross-regional and even cross-border is developing rapidly, and it has become an important part of our country’s manufacturing industry. The collaborative processing manufacturing industry is a kind of general industrial model that is driven by the orders, drawings and technical requirements of the“dominant enterprise”(OEM or committing factory, etc.) and completed the manufacturing procedure by the“collaborative processing enterprise”. With the economic globalization and the rapid development of information network, the networked manufacturing model has gradually become an important development trend of the modern manufacturing enterprises. With the support of the networked manufacturing system, the choice of the dominant enterprises choosing the collaborative processing resoures is no longer confined to a number of enterprises and a few regions. It is gradually becoming a global and networked optimal utilization model. The current research and application issues in the field of networked collaborative processing, such as how to make the enterprises have a broader way to optimally allocate collaborative processing resoures and how to promote the capability of information exchange and business collaboration between the collaborative enterprises more efficiently, are studied intensely. Based on the internal and external existing research results, the optimal resources allocating methods of networked collaborative processing and its support system are studied in this paper.Firstly, based on the analysis of the Networked Collaborative Processing Resources(NCPR)’s compositive attributes and characteristics, the NCPR’s semantic description and integrated service mechanism are studied, including the NCPR’s ontology model and semantic description method. A kind of NCPR’s register and publish mechanism based on the expanded Universal Description Discovery and Integration protocol is proposed. The search-match algorithm which could realize the combination of the grammar and semantic layer is proposed, too. On this basis, a new NCPR integrated service operation model that could enhance the fast sharing and high-effectively using of the resources is established. Secondly, the optimal selecting factors to NCPR are considered, and a kind of decision-making target system and framework model for NCPR is proposed. The system contains seven target factors, such as T (response speed), Q (collaborative quality), C (collaborative cost), R (the ability to ensure collaborative resources), I (the ability to exchange collaborative information), S (the technology security and confidentiality in the collaborative processing) and K (the collaborative enterprises’knowledge accumulation and capability of sustainable development). And focused on the invisibility and fuzziness of information in the decision-making procedure, a grey related algorithm for the model analysis is designed. At last, a case study in which a decision-making problem is analyzed and solved successfully shows the model and method is correct and practical.Thirdly, according to the characteristics like multi-task, multi-candidate resource, multi-objective and dynamic environment in the optimal allocation of collaborative processing resources, this paper adopts a kind of optimal allocation model for multi-task collaborative processing resources which was constructed by using the linear weighted method. In this model, collaborative processing time, collaborative processing cost and collaborative processing quality are set as target factors. And the genetic algorithm is introduced into the model solution, an application example is also given to prove the validity and feasibility of the approach.Then, aimed at the monitoring and management requirement in the networked collaborative processing procedure, this paper a networked collaborative processing support system that is based on the networked multi-function interactive information terminal is builded, and the system’s architecture, function structure and operation mode are constructed. Meanwhile, the collaborative processing information exchange and business collaborative support technology based on the networked multi-function interactive information terminal and some key technologies for implementing the system are researched. The above-mentioned technologies include the real-time information collection, collaborative manufacturability analysis for collaborative tasks, the collaborative compilation of NC program and so on.Finally, combined with the implementation experience of the networked manufacturing systems for netlike region with a central city in Chongqing and the present situation and requirement of motorcycle parts manufacturing enterprises, a set of networked collaborative processing operation support system for motorcycle parts manufacturing enterprises is developed. The system has been applied to a few Chongqing motorcycle parts manufacturing enterprises, and good results are obtained.
