Abstract

The automobile body painting production system exists in the backward management concept of focusing on production and ignoring environmental protection, focusing on traditional technology and unwilling to innovate, etc., high production cost and environmental protection standards, which have had a negative impact on the industry's long-term growth. Based on the value stream mapping (VSM) analysis technology, the current situation of the value stream of the body spraying process of TJ Automobile Manufacturing Company is analyzed, the problem of waste in the production process of automobile body painting system affected by Eliminate Combine Rearrange Simplify (ECRS)a four-step problem-solving technique was studied and analyzed, a new method for the application of value stream graph analysis technology in the digital transformation environment is proposed, and a suitable production improvement scheme for the body painting system is formulated by using the new method, which increases the value-added operation time of the painting production process by 9.5% and reduces the non-value-added operation time by 12.5%. The number of operators was reduced by 18.8%, the value-added ratio was increased accordingly, the scrap rate was reduced by 8%, and the exhaust gas purification rate was increased by 66%, which brought good economic and social benefits to the enterprise and provided a successful case for the application of lean production VSM in the digital transformation environment. The paper extends knowledge in the area of digital transformation and lean production by helping us to establish and explain the relationship between lean production management methods and the promotion of new energy vehicle body coating performance from a dual perspective of digital transformation and VSM. None of the previous studies have considered the combined application of the studied digital transformation and VSM lean management approaches.

基于数字化转型和VSM双重视角的新能源汽车车身涂装精益生产管理研究
汽车车身涂装生产体系存在重生产而忽视环保、重传统技术而不愿创新等落后的管理理念,生产成本和环保标准过高,对行业的长期增长产生了负面影响。基于价值流映射(VSM)分析技术,分析了TJ汽车制造公司车身喷涂工艺价值流现状,研究分析了采用消除、组合、重排、简化(ECRS)四步解决技术对汽车车身涂装系统生产过程中的浪费问题;提出了一种在数字化转型环境下应用价值流图分析技术的新方法,并利用新方法制定了适合人体彩绘系统的生产改进方案,使彩绘生产过程的增值操作时间增加9.5%,非增值操作时间减少12.5%。操作人员减少18.8%,增值比相应提高,废品率降低8%,废气净化率提高66%,为企业带来了良好的经济效益和社会效益,为精益生产VSM在数字化转型环境中的应用提供了成功案例。本文从数字化转型和VSM的双重视角,帮助我们建立和解释了精益生产管理方法与新能源汽车车身涂层性能提升之间的关系,从而拓展了数字化转型和精益生产领域的知识。之前的研究都没有考虑到所研究的数字化转型和VSM精益管理方法的结合应用。
