【摘要】：低成本高效率生产、快速响应市场需求、保证产品质量,以及持续改善现场管理一直是当今企业面临的共同问题。产品质量是直接决定用户对公司满意程度的关键因素,良好的产品质量是公司在全球竞争形势下赖以生存的根基,也是超越竞争对手的核心竞争力。如何结合现场实际情况,运用精益理论和工具,使产品质量在现场生产管理的过程中持续不断的改进成为了中小型企业管理的重点和难点。首先,论文介绍了压缩机的市场需求以及在国内国外的应用情况。随着能源问题的日益突出和环境保护的逐渐加强,压缩天然气已经成为汽车的重要能源之一,加气站天然气压缩机具有巨大的市场需求。对CCF公司天然气压缩机现场质量管理现状进行了分析,包括生产工艺、生产过程、总装流程等。其次,在对CCF公司现场质量现状分析的基础上,总结出了公司现场质量管理存在的主要问题,并深刻剖析了产生问题的主要原因。同时对质量损失、造成事故原因等进行了统计分析。最后,作者在全程参加精益生产小组和质量管理方法改进研究的基础上,结合CCF公司实际现场质量管理情况,提出采用精益生产和六西格玛相结合的方法来制定提高生产效率和改善现场质量管理的机制。主要针对降低现场成品的缺陷率和减少质量成本,设计了基于精益六西格玛的质量改进方案,以及基于现场管理的质量管理改善方案。实际运行结果表明,采用精益生产与六西格玛相结合的质量改善方法,CCF公司现场质量改善效果明显。
[Abstract]:Low cost and high efficiency production, quick response to market demand, guarantee of product quality and continuous improvement of field management are the common problems faced by enterprises today. Product quality is the key factor that directly determines customer satisfaction with the company. Good product quality is the foundation of the company's survival in the global competitive situation, and it is also the core competitiveness beyond the competitors. How to combine the actual situation on the spot, using lean theory and tools, The continuous improvement of product quality in the process of on-site production management has become the focus and difficulty in the management of small and medium-sized enterprises. First of all, The paper introduces the market demand of compressor and its application at home and abroad. With the increasingly prominent energy problems and the gradual strengthening of environmental protection, compressed natural gas has become one of the important energy sources for automobiles. The natural gas compressor of filling station has huge market demand. This paper analyzes the present situation of field quality management of natural gas compressor in CCF company, including production process, production process, final assembly flow and so on. Secondly, On the basis of the analysis of the present situation of the field quality of CCF Company, this paper sums up the main problems existing in the field quality management of the company, and deeply analyzes the main causes of the problems. At the same time, the quality loss is analyzed. Finally, on the basis of participating in the Lean production Group and improving the quality management method, the author combined with the actual site quality management situation of CCF Company. The method of combining lean production with six Sigma is put forward to establish a mechanism to improve production efficiency and improve field quality management, which is aimed at reducing the defect rate and quality cost of the finished products on site. A quality improvement scheme based on Lean six Sigma and a quality management improvement scheme based on field management are designed. The quality improvement method combining lean production with six Sigma is obvious in CCF.
