【摘要】：最近几年，中国大陆经济建设持续高速发展，特别是基础建设和房地产产业空前发展，在加快我国城市化进程的同时,也导致我国电梯需求量越来越大。当前市场竞争越来越激烈，国际上具有竞争力的外资电梯公司先后进入中国。A企业也是从事电梯生产的佼佼者，在这种激烈竞争的背景下，保持领先地位就必须在保证产品质量的前提下持续地科学地降低产品成本提高产品质量。另一方面, A企业全球约有20多家分公司，由于发展战略的变动，韩国分公司即将在2013关闭，市场陆续转向中国市场，所以从明年开始A企业的产量就会有很大的提升。未来的一年里车间的生产能力面临极大的考验，所以必须提高生产效率来满足客户的需求节拍。为了不断降低成本提高质量，精益生产的理论和方法正在被A企业广泛认可和采用。本课题源于该企业的一条厅门生产线的现场改进。本文基于精益生产的相关理论知识，以A公司的厅门生产线现场改善为研究对象进行一系列的分析研究，系统地论述了A公司对厅门生产线的持续改善活动，采用价值流程图分析，，文献研究法，模拟法、案例研究方法，在提高生产效率的同时节省了大量的现场使用面积，缩短了电梯厅门的制造周期，消除了制造过程中大量的浪费，从而使A企业的产品获得更多的竞争优势。对于实施厅门现场改善的过程中遇到的一些实际问题，本项目收集了有关的资料及相关经验，通过对厅门的加工工艺流程、标准作业分析、布局调整、价值流图等深入研究，实现了提高生产效率，减少序间库存，降低产品成本的目的。强调了企业实施精益生产不能生搬硬套，应根据自身的实际情况灵活运用精益知识和工业工程的知识。本次改善对A公司以及同类制造企业在实施精益生产的现场改善的活动起到了一定的指导意义。
[Abstract]:In recent years, the economic construction in mainland China has continued to develop at a high speed, especially the unprecedented development of infrastructure and real estate industries. While speeding up the process of urbanization in China, It also leads to the increasing demand for elevators in our country. At present, the market competition is becoming more and more intense. The international competitive foreign elevator companies have entered China's .A enterprises successively and are also the best ones engaged in elevator production. Under the background of this fierce competition, To maintain the leading position, we must continuously and scientifically reduce the product cost and improve the product quality on the premise of ensuring the product quality. On the other hand, Enterprise A has about 20 branches around the world, because of the change in development strategy. The Korean branch will close in 2013, and the market will turn to the Chinese market one after another, so starting from next year, the production of Enterprise A will be greatly improved. In the coming year, the production capacity of the workshop will face a great test. So we must improve the production efficiency to meet the needs of customers. In order to continuously reduce the cost and improve the quality, The theory and method of lean production is being widely accepted and adopted by Enterprise A. this topic originates from the field improvement of a hall door production line in this enterprise. Based on the relevant theoretical knowledge of lean production, this paper makes a series of analysis and research on the field improvement of A company's hall door production line, and systematically discusses the continuous improvement activities of A company to the hall door production line. Value flow chart analysis, literature research, simulation and case study are used to improve the production efficiency and save a lot of area in the field, shorten the manufacturing cycle of the elevator door, and eliminate a large amount of waste in the manufacturing process. As a result, A enterprise products to obtain more competitive advantage. For some practical problems encountered in the process of implementing the on-site improvement of the hall door, the project has collected relevant information and relevant experience, and through in-depth research on the processing process, standard operation analysis, layout adjustment, value flow chart, etc., of the hall door, The purpose of improving production efficiency, reducing stock between orders and reducing product cost is realized. Lean knowledge and industrial engineering knowledge should be used flexibly according to the actual situation. This improvement has a certain guiding significance for company A and similar manufacturing enterprises in the implementation of Lean production site improvement activities.
