【摘要】：第二次世界大战以后,日本丰田汽车企业通过使用精益生产方式来不断提高市场竞争力。20世纪70年代后期,欧美国家和日本企业开始全面使用精益生产管理模式,逐渐形成了十分独特的精益生产文化,精益生产为这些企业带来巨大的市场竞争力,成就了许多大型跨国企业。我国早在二十世纪八十年代就开始,一些大型企业就开始引进了精益生产,期待借鉴外部先进的经验和管理方法解决生产中存在的问题,但在实际操作过程中由于受到企业文化、管理体制、员工素质等多方面因素限制,发现难以获得成功。近几年随着外资企业的增多,国内的一些优秀企业通过交流学习,正在不断摸索适合自己的精益生产模式。本文结合W公司螺杆式压缩机实际生产状况,通过价值流分析方法,利用价值流图对企业生产流程中各个环节进行分析,查找企业各个生产环节中存在得浪费原因,研究如何运用精益生产理论指导企业优化现有的螺杆式压缩机生产线。分析W公司螺杆式压缩机生产线存在的问题,提出优化方案,帮组企业改善生产状态。文章首先介绍选题背景及意义,对精益生产理论及价值流分析法进行简要的介绍。利用价值图分析方法对W公司螺杆式压缩机的生产装配线进行全面解析,绘制价值流图。通过分析当前价值流图发现生产制造系统的需要改善的环节。根据W企业2017年螺杆式压缩机销售预测和最新发展规划,以精益生产理论为指导,为W公司设计螺杆式压缩机生产的最新价值流图,研究制定螺杆式压缩机生产制造系统优化方案,设计出符合现实意义的生产制造系统,并组织实施。课题研究的过程中,笔者基于客户不同的需求,对螺杆杆式压缩机生产系统产能以及在线库存等问题进行了详细的分析和阐述。利用详细数据进行计算,对实施精益生产后杆式压缩机生产的各个指标进行了详细的论证,指出了精益生产方式本身所具有的优势。目前,越来越多的企业已经认识到精益生产理论对企业发展具有的现实意义,尝试利用精益理论来优化企业生产,期待取得成功。但是对于企业来说,必须认识到精益生产方式并不是通过一次生产线的优化就可以达到的,精益生产实际上是一个持续改善,追求尽善尽美的过程。只有在分析-改善-再分析-再改善的过程中,不断地消除浪费,研究摸索符合企业自身的生产方式,企业才会在不断完善中发展壮大。精益理论虽然时一种外来理论,但是随着在各行各业应用的增多,它也一定会在中国得到丰富和升华,为中国企业发展壮大发挥巨大的作用。
[Abstract]:After the second World War, Toyota automobile enterprises in Japan used lean production methods to continuously improve their market competitiveness. In the late 1970s, European and American countries and Japanese enterprises began to use lean production management mode in an all-round way. Gradually formed a very unique lean production culture, lean production for these enterprises to bring huge market competitiveness, has achieved many large multinational enterprises. As early as the 1980s, some large enterprises in China began to introduce lean production, hoping to learn from advanced external experience and management methods to solve the problems in production. However, due to the limitations of corporate culture, management system, staff quality and so on, it is difficult to achieve success in the actual operation process. In recent years, with the increase of foreign-funded enterprises, some excellent enterprises in China are exploring their own lean production model through exchange and study. Combined with the actual production situation of screw compressor in W Company, this paper analyzes every link in the production process by using value flow diagram through value flow analysis method, and finds out the reasons for waste in every production link of enterprise. This paper studies how to use lean production theory to guide enterprises to optimize the existing screw compressor production line. This paper analyzes the problems existing in the production line of screw compressor in W Company, and puts forward the optimization scheme to improve the production status of the group enterprise. This paper first introduces the background and significance of the topic, and briefly introduces the lean production theory and value flow analysis method. The production and assembly line of screw compressor in W Company is analyzed by using value chart analysis method, and the value flow diagram is drawn. Through the analysis of the current value flow diagram, we find that the manufacturing system needs to be improved. According to the sales forecast and latest development plan of screw compressor in 2017, and guided by lean production theory, this paper designs the latest value flow chart of screw compressor production for W Company. The optimization scheme of manufacturing system for screw compressor is studied, and the production and manufacturing system is designed and implemented. In the course of the research, based on the different needs of the customers, the production capacity and online inventory of screw rod compressor production system are analyzed and expounded in detail. By using the detailed data to calculate, every index of the rod compressor production after lean production is demonstrated in detail, and the advantages of lean production mode itself are pointed out. At present, more and more enterprises have realized the practical significance of lean production theory for the development of enterprises, try to use lean theory to optimize enterprise production, expect success. But for enterprises, we must realize that lean production is not achieved through the optimization of a production line, lean production is in fact a continuous improvement, the pursuit of perfect process. Only in the process of analysis-better-re-analysis-re-improvement, constantly eliminating waste, researching and groping the mode of production in line with the enterprise itself, can the enterprise develop and grow stronger and stronger in the process of continuous improvement. Lean theory is a kind of foreign theory, but with the increase of its application in various industries, it will be enriched and sublimated in China, which will play a great role in the development and growth of Chinese enterprises.
