【摘要】：随着社会个性化需求越来越突出,多批小量的生产方式越来越多。同时,近年来中国劳动力价格节节攀升,企业的生产成本压力非常大。企业除面临的成本竞争压力之外,在生产柔性和客户响应速度方面的要求也越来越高。精益生产是多批小量型企业降低成本、提高响应速度,增加竞争力的有效工具。HG公司的产品的型号和种类特别多,而每种型号产品需求的数量少,是一个典型的多批小量的生产方式,因此在HG公司实施精益生产是非常可行和必要的。本文以HG公司TINGO产品线为研究对象,运用精益生产理论如流程化生产、快速换型等理论,采用专家研讨法和比较分析法对TINGO产品线的生产布局、生产柔性和厂内物流等问题进行研究。本文首先介绍了研究背景和国内外的研究现状,并对精益生产的理论和方法进行了详细的介绍,如准时制生产、流程化生产、快速换线、全员质量管理、TPM等理论知识。接着对HG公司的精益生产现状进行分析调查,着重就生产布局、生产柔性和厂内物流几方面进行了问题分析。然后针对上述发现的问题,结合精益生产方式的有关理论和IE相关的知识、工具,提出改善和解决HG公司精益生产问题的方法和途径。在HG公司TINGO生产线实施精益生产过程中,本文主要从以下几个方面进行改善:1)通过U型线设计来改善装配生产线布局,并将焊接线布局由按工艺布置改为按产品布置;2)通过SMED工具来减少换型时间,改善生产柔性;3)通过厂内物流路线图分析提出改善厂内物流的方案。最后在改善方案实施后,对改善效果进行了总结和评估,其中在制品库存下降了35%,生产效率提高了2.4%。本文对未完成项目的效果进行了预测,如果厂内物流改善方案得到实施,物料员预计节省40%。同时,在本文提出了下一步的改善重点和方向。本文通过精益生产和工业工程技术相结合的方法,对HG公司的流程化生产和生产柔性进行改善研究并取得了不错的成果,为类似企业提供了参考案例。不同的企业在推行精益生产方式时需要根据企业自身的特点选择合适的推行策略。
[Abstract]:With the social individuation demand more and more prominent, many lots of small production methods are more and more. At the same time, in recent years, China's labor prices continue to rise, the pressure on the production costs of enterprises is very great. In addition to the cost competition pressure, the production flexibility and customer response speed are more and more demanding. Lean production is an effective tool to reduce cost, improve response speed and increase competitiveness. HG Company has a large number of models and types of products, while each type of product demand is small. It is a typical multi-batch and small production mode, so it is very feasible and necessary to implement lean production in HG Company. This paper takes the TINGO product line of HG Company as the research object, uses the lean production theory such as the flow production, the quick change model and so on, adopts the expert discussion method and the comparative analysis method to produce the layout of the TINGO product line. Production flexibility and plant logistics and other issues are studied. This paper first introduces the research background and domestic and international research status, and introduces the theory and methods of lean production in detail, such as just-in-time production, process-oriented production, quick line changing, all-staff quality management, TPM and so on. Then the present situation of lean production in HG Company is analyzed, and the problems in production layout, production flexibility and in-plant logistics are analyzed. Then according to the above problems, combined with the theory of lean production and the knowledge of IE, the paper puts forward the methods and ways to improve and solve the problem of lean production in HG Company. In the lean production process of TINGO production line of HG Company, this paper improves the layout of assembly line mainly from the following several aspects: (1) improve the layout of assembly line through U-line design. The welding line layout is changed from the process layout to the product layout by using SMED tools to reduce the changing time and improve the flexibility of production. Through the analysis of the in-plant logistics road map, the scheme of improving the in-plant logistics is put forward. Finally, after the implementation of the improvement program, the improvement effect was summarized and evaluated, in which the in-process inventory decreased by 35 and the production efficiency increased by 2.4 percent. In this paper, the effect of the unfinished project is predicted. If the logistics improvement scheme is implemented, the material worker is expected to save 40%. At the same time, in this paper, the next step to improve the focus and direction. Through the combination of lean production and industrial engineering technology, this paper studies the improvement of HG Company's flowsheet production and production flexibility and obtains good results, which provides a reference case for similar enterprises. Different enterprises should choose appropriate strategies according to their own characteristics when implementing lean production.
