【摘要】：作为中国第五大汽车集团——北京汽车——旗下重要的合资企业,北京奔驰的发展已经成为集团营业能力的重要增长点。在竞争激烈的国内豪华车细分市场,单靠品牌优势已经很难谋求长远发展。因此,北京奔驰看到了当前HPV(单车工时)与竞争对手存在的差距,并着力通过生产工艺平衡再造、高效的线边物流方案、以及适应多产品共线生产的排序组织方式,来提升现有生产效率,从而实现行业竞争力。本文意指识别生产爬坡过程中造成产能损失的影响因素,结合工业工程的理论和方法分析各因素间的关联以及影响;从而理解单一行为和系统之间存在的动态联系,以便在解决爬坡瓶颈中准确识别主要矛盾并对症下药。本文以工业工程理论和方法论为基础,以北京奔驰MRA1总装车间内饰一生产线为研究对象,探讨并研究了如何应用现代工业工程理论的思路和方法,管理生产爬坡阶段并解决瓶颈问题。分析并探究了爬坡阶段内工艺规划与线边物流、以及多车型混线生产模式下排序组织形式之间的相互影响及制约关系。论文采用理论探究和方法实践相结合的方式,通过应用多种图表分析——瀑布图、折线图、柱状图等、以及生产线平衡分析——平衡墙,和工时分析等理论和工具;研究了如何在生产爬坡过程中围绕效率提升主题,通过系统化、流程化的解决方案,有机地将工艺规划同线边物流方案以及多车型排序组织方案联系起来,设计出整套瓶颈解决方案,并最终实现精益管理,以实现具有竞争力的HPV(Hours per Vehicle单车工时)目标。本文中实践的理论和方法,如Top up、Shopping cart,体现了工业工程基础IE理论在汽车生产领域中的创新和发展;因此,文中论述的理论和方法,在同行业进行生产线效率提升活动中,具有一定借鉴价值。
[Abstract]:As an important joint venture of China's fifth largest auto group, Beijing Automotive, Beijing Mercedes-Benz has become an important growth point of the Group's business capacity. In the competitive domestic luxury car segment market, it is difficult to seek long-term development by brand advantages alone. Therefore, Beijing Mercedes-Benz has seen the gap between the current HPV (cycle time) and its competitors, and has focused on rebalancing production processes, efficient line side logistics schemes, and a sort of organization that adapts to multi-product collinear production. To improve the existing production efficiency, so as to achieve industry competitiveness. This paper means to identify the factors that affect the productivity loss in the process of production climbing, and to analyze the relationship and influence of each factor in combination with the theory and method of industrial engineering, so as to understand the dynamic relationship between the single behavior and the system. In order to solve the slope-climbing bottleneck in the accurate identification of major contradictions and the right remedy. Based on the theory and methodology of industrial engineering, this paper discusses and studies how to apply the modern industrial engineering theory to the production line of Beijing Benz MRA1 assembly workshop. Manage the climbing stage of production and resolve the bottleneck problem. This paper analyzes and probes into the mutual influence and restriction relationship between the process planning and the line side logistics in the climbing stage, as well as the sort organization form under the multi-vehicle mixed line production mode. This paper adopts the way of combining theory and practice, through the application of many kinds of chart analysis-waterfall diagram, broken line diagram, bar chart, and so on, as well as production line balance analysis-balance wall, and man-hour analysis and other theories and tools. This paper studies how to improve efficiency in the process of production climbing, and organically link process planning with line side logistics scheme and multi-vehicle scheduling scheme through systematic and flow-oriented solution. The whole bottleneck solution is designed and the lean management is finally realized to achieve the competitive goal of HPV (Hours per Vehicle cycle time. The theories and methods in this paper, such as Top up,Shopping cart, embody the innovation and development of the basic IE theory of industrial engineering in the field of automobile production, therefore, the theories and methods discussed in this paper are used to promote the efficiency of production line in the same industry. It has certain reference value.
