【摘要】：生产线是企业直接创造效益的场所,是企业所有信息的原始发源地,也是各种问题萌芽产生的场所。生产线改善作为管理的深化,它以增进顾客满意度为目标,使用持续改善理论对生产现场的人员、设备、物料、作业方法、生产环境等各生产要素进行持续的改善,实现各生产要素的合理配置,从而减少生产过程中的浪费,降低生产成本,提高生产效率和产品质量,对企业提高自身的竞争力具有十分重要的意义。本文首先介绍了精益生产的发展背景、核心思想以及生产线改善的精益原则和生产线改善的相关方法,同时对离散事件动态系统仿真技术做了进一步阐述。其次文章简单介绍了磁头产品的整体工艺并具体到其中的row bar加工生产线,在对row bar加工生产线进行了流程分析,生产线布局分析和操作分析之后,发现当前生产线存在的问题,基于生产线数据整理与分析的基础上,运用Arena仿真平台对生产线进行了仿真模型的建立,并对所建模型进行了有效性的验证。然后遵循精益生产的理念,对row bar加工生产线进行流程改善、时间分析,人机操作分析及对生产线进行布局改善分析,在这些分析和改善的基础上提出C公司row bar加工生产线布局的优化方案,并对改善后的方案进行仿真分析,比较改善前后的生产力数据以及评价改善方案的优劣。最后在总结全文理论与实际应用的研究成果基础上,指出本文在研究过程中存在的局限性与不足之处,为后续的研究工作提供了拓展的空间与改善的方向。
[Abstract]:Production line is the place where enterprises directly create benefits, the original source of all enterprise information, and the place where all kinds of problems sprout. Production line improvement as the deepening of management, it aims to improve customer satisfaction, using the theory of continuous improvement of production site personnel, equipment, materials, working methods, production environment and other production factors for continuous improvement, It is of great significance for enterprises to improve their competitiveness by realizing rational allocation of production factors, reducing waste in production process, reducing production cost, and improving production efficiency and product quality. This paper first introduces the development background of lean production, the core idea, the lean principle of production line improvement and the relevant methods of production line improvement. At the same time, the discrete event dynamic system simulation technology is further expounded. Secondly, the paper introduces the whole process of the magnetic head product and the row bar production line. After analyzing the process, layout and operation of the row bar processing line, Based on the analysis of the production line data, the Arena simulation platform is used to build the simulation model of the production line, and the validity of the model is verified. Then follow the concept of lean production, row bar processing line process improvement, time analysis, man-machine operation analysis and layout improvement analysis of the production line, On the basis of these analysis and improvement, the optimization scheme of row bar production line layout of C Company is put forward, and the improved scheme is simulated and analyzed, the productivity data before and after the improvement are compared and the advantages and disadvantages of the improved scheme are evaluated. Finally, on the basis of summarizing the research results of the theory and practical application, this paper points out the limitations and shortcomings in the research process, which provides the space for further research and the direction of improvement.
