摘要
摘要
近年来国内汽车制造行业竞争不断加剧,国家法规要求不断加严,新冠疫情等
始料未及的特殊情况亦成为催化剂。TS公司是国内汽车零部件制造企业,面对当前
形势,该企业所面临的最迫切问题即为制造系统效率有待提升。本文通过运用精益
管理的方法,帮助企业提升制造系统效率,最终达到提升企业竞争力和巩固市场地
位的目的。更希望归纳精益管理思想的实践应用经验,探索适合 TS公司的精益改进
之路,并对其他类似性质的行业提供改善活动的借鉴和参考。
本文首先探讨对 TS公司推行精益管理的必要性和可行性,然后借助“5M”分析
法,分别从“人”、“机”、“料”、“法”、“环”五个方面对影响效率存在的问题进行分析,
并分析了问题出现的成因,得出问题主要是由于全员参与不足、设备故障率高、物
料摆放不合理、标准化作业水平低、生产环境混乱等原因。然后针对已识别出的具
体问题进行提升方案的设计。“人”的方面本文建议实施精益培训、现场管理会议及
改善提案,打造精益环境和氛围。“机”方面聚焦瓶颈设备的识别与改造。“料”改进方
面,本文探讨了供应链改进的“逆序原则”,从物料箱的选择、拉动系统的实施和物
流配送中 AGV的应用进行实际案例阐述。“法”改进方面,通过多个操作流程分析
工具运用、线平衡及标准作业持续改进、全面质量管理和问题解决等方法,提出在
流程方法上的方案。“环”改进方面,本文则建议采用“5S”和人机工程的工具。
本文从“5M”维度进行 TS公司生产线效率提升研究,本文形成完整的效率提升
的精益改善方案,解决 TS公司制造系统的难点。本文通过对各个维度的方案进行实
施和跟踪来验证所提供方案的效果,与此同时,用两个效率关键指标 JPH(单位时
间产出量)和 HPV(单台制造工时),对效率提升结果进行效果评估,并提出分层
审核的固化方法。最后验证了本文设计的效率提升方案在 TS公司制造系统中的可
实施性和有效性,最终帮助企业优化交付、提升质量和降低成本。

Abstract
Abstract
In recent years, the competition in the domestic automobile manufacturing industry
has been intensified, and national regulations have been tightened. COVID-19 and other
special circumstances that have not yet been anticipated have become catalysts. TS
Company is a leading enterprise in domestic auto parts manufacturing. Facing the current
situation, the most urgent problem faced by the enterprise is that the efficiency of
manufacturing system needs to be improved. Based on this,this thesis uses the method of
lean management to help enterprises improve the efficiency of manufacturing system,
and finally achieve the purpose of improving enterprise competitiveness and consolidating
market position. I hope to sum up the practical application experience of lean management
thought, explore the way of lean improvement suitable for TS Company, and provide
reference and reference for other similar industries.
This thesis first discusses the necessity and feasibility of implementing lean
management in TS Company, then with the help of "5m" analysis method, divides the
information of the problems affecting efficiency from the five aspects of "human",
"machine", "material", "method" and "environment", analyzes the causes of the
problems, and comes to the conclusion that the problems are mainly due to insufficient
participation of all staff, high failure rate It is caused by unreasonable material
placement, low level of standardized operation, chaotic production environment and
other reasons. Then the lifting scheme is designed according to the identified specific
problems. In terms of "people", this thesis proposes to implement lean training, on-site
management meeting and improvement proposal to create a lean environment and
atmosphere. The "machine" aspect focuses on the identification and transformation of
bottleneck equipment. In the aspect of "material" improvement, this thesis discusses the
"reverse order principle" of supply chain improvement, and expounds the practical cases
from the selection of material box, the implementation of pull system and the application
of AGV in logistics distribution. In terms of "method" improvement, the scheme on
process method is put forward through the application of multiple operation process
analysis tools, line balance, continuous improvement of standard operation, total
quality management and problem solving. In the aspect of "ring" improvement, this
thesis suggests using "5S" and ergonomic tools.
