【摘要】：供应链全球化、客户定制化使汽车制造商们正处于一个前所未有的激烈竞争环境之中。目前，汽车整车生产任务全过程涉及到大量生产任务单、BOM清单、质量检验表单和仓库表单等数据信息，一方面，这些数据信息在生产任务进行的不同阶段处于不同的信息系统中，信息孤岛现象严重；另一方面，对这些数据收集和处理不规范、不及时、不完整，从而导致了汽车整车生产企业各级管理者的决策得不到生产进度、生产质量和生产物料等方面信息的有效支撑。本论文在借鉴国内外的研究成果的基础上，结合制造执行系统(Manufacturing Execution System,MES)的基本理论，对汽车整车生产任务实时监控系统进行一些研究和探索。首先，在对汽车整车生产特点分析的基础上，提出了一个包括作业、质检、人力资源、设备、物料、防错等六维度汽车整车生产任务的全过程信息模型（wholeprocess information model，WPIM）。其次，分析了汽车整车生产任务实时监控系统管理现状与信息化需求，在此基础上，建立了一套基于WPIM的汽车整车生产任务实时监控系统，并研究了该系统的结构体系和运行模式。然后，在以上的研究基础上，，重点研究了基于本体的语义信息集成方法和基于组件技术的汽车整车生产任务执行情况可视化动态监控等关键技术。最后，借鉴以上的研究成果，结合重庆某汽车整车生产车间的实际需求，参与设计和开发了一套汽车整车生产任务实时监控系统，并在重庆鑫源汽车整车生产车间进行了实施与应用，取得了良好的应用效果。
[Abstract]:With the globalization of supply chain and customization of customers, automakers are in an unprecedented competitive environment. At present, the whole process of automobile production involves a large number of data information, such as BOM list, quality inspection form and warehouse form. These data information are in different information systems at different stages of production tasks, and the phenomenon of information isolation is serious; on the other hand, the collection and processing of these data is not standardized, timely and incomplete. As a result, the decision of the managers at all levels in the automobile manufacturing enterprises is not effectively supported by the information of production progress, production quality and production materials. Based on the research results at home and abroad and the basic theory of Manufacturing execution system (mes), this paper makes some research and exploration on the real-time monitoring system of automobile production task. Firstly, on the basis of analyzing the characteristics of vehicle production, a whole process information model (wholeprocess information model-WPIM) is proposed, which includes six dimensions: operation, quality inspection, human resources, equipment, material, error prevention and so on. Secondly, this paper analyzes the current situation and information requirement of the real-time monitoring system for vehicle production task, and then establishes a real-time monitoring system of vehicle production task based on WPIM. The structure and operation mode of the system are also studied. Then, on the basis of the above research, the key technologies such as ontology based semantic information integration method and visual dynamic monitoring of vehicle production tasks based on component technology are studied. Finally, referring to the above research results and combining with the actual demand of a vehicle production workshop in Chongqing, a real-time monitoring system for vehicle production task is designed and developed. It has been carried out and applied in the production workshop of Xinyuan automobile in Chongqing, and good application effect has been obtained.
