【摘要】：本文主要是基于价值流分析对D公司生产效率进行的研究。D公司中国工厂是一家英国独资公司,在中国建厂已经9年,是全球著名的生产天然橡胶安全套的企业,整体利润较高,但近几年因成本上涨,导致利润下滑,因此迫切需要一些改革来改善利润下滑的问题。通过查阅国内外关于价值流和生产效率的各种资料,并结合国内外这方面的理论和研究,通过查看工厂过去6个月的数据,以及采集工厂目前各部门的数据,如生产部、质量部、物流部、设备维修部等,进行了详细的分析,将其运用到D公司提高生产效率的过程改善中。本文采用了文献分析法,现场调研法,价值流分析法。通过查找国内外相关文献,了解行业的动态,确定了未来的改善方向。并采用了查看生产记录方法,得到生产过程中的工时、库存数量、生产时间等原始数据,运用对比论证、鱼骨图分析等方法,对得到和采集的数据进行分析,找到产生问题的根本原因。并评估现场生产过程,对流程进行优化、缩短制造周期。对库存数量进行监控和设定最高限度,降低库存数量。本文通过精益生产综述,对价值流进行了介绍,了解了价值流程图的工作流程,掌握了价值流程图的工作步骤。通过运用此分析方法,绘制出现在的价值流程图,找出生产系统目前存在的主要问题。找出改善点,如线平衡,节拍时间,生产模式,并绘制出未来的价值流程图。通过运用价值流分析的思想,设计生产系统整体改进方案。例如通过提高合格率减少浪费,提高机器运转速度增大产出量,从而提高生产效率。本文共分为六章。第1章阐述选题的背景和意义,包含理论意义和现实意义;第2章对精益生产方法进行大致的介绍;第3章详细介绍并分析D公司生产系统现状,包括D公司介绍,工艺设备,人员状况;第4章是D公司的改进方案思路,方案目标和整体方案设计;第5章是D公司改善方案的详细设计过程,涉及各车间的生产节拍,以及半成品、成品库存,采购物料交期,物料检测周期;最后一个章节是对全文的分析和总结,得出结论,并分析研究中的不足。
[Abstract]:This paper is mainly based on the value flow analysis of the production efficiency of company D. D Company China factory is a British wholly owned company in China has been established for 9 years. Is the world famous production natural rubber condom enterprise, the overall profit is higher, but in recent years because of the cost rise, causes the profit to fall. Therefore, some reforms are urgently needed to improve the problem of profit decline. By consulting various information about value flow and production efficiency at home and abroad, and combining with domestic and foreign theory and research in this field. By reviewing the data of the past 6 months, and collecting the data of the current departments of the factory, such as production, quality, logistics, equipment maintenance and so on, the detailed analysis was carried out. This paper uses the literature analysis method, field investigation method, value flow analysis method to improve the process of improving the production efficiency of D Company. By looking up the relevant literature at home and abroad, to understand the industry dynamics. The future direction of improvement is determined. The method of checking production records is used to obtain the original data of working hours, inventory quantity, production time and so on. The methods of comparison and demonstration, fish bone map analysis and so on are used. Analyze the obtained and collected data, find out the root cause of the problem, and evaluate the production process, optimize the process, shorten the manufacturing cycle, monitor the inventory and set the maximum limit. This paper introduces the value flow through the lean production summary, understands the workflow of the value flow chart, and grasps the working steps of the value flow chart. Draw the value flow chart, find out the main problems existing in the production system. Find out the improvement points, such as line balance, rhythm time, production mode. And draw out the future value flow chart. By using the idea of value flow analysis, design the overall improvement scheme of production system. For example, by increasing the qualified rate to reduce waste, improve the speed of machine operation and increase the output. In order to improve production efficiency, this paper is divided into six chapters. Chapter 1 describes the background and significance of the topic, including theoretical and practical significance; Chapter 2 gives a general introduction to lean production methods; Chapter 3 introduces and analyzes the present situation of D Company's production system, including D Company's introduction, process equipment and personnel status. The fourth chapter is the D company's improvement program ideas, program objectives and the overall scheme design; Chapter 5 is the detailed design process of company D's improvement scheme, which involves the production rhythm of each workshop, as well as semi-finished products, finished product inventory, purchasing material delivery period, material testing cycle; The last chapter is the analysis and summary of the full text, draw a conclusion, and analyze the deficiencies in the study.
