Firstly, this paper expounds the background and significance of applying lean production method in this research, as well as the development of lean production method in various countries over the years, and expounds the relevant theories and tools of lean production method. Secondly, based on the description of the current situation of LK's field management, the existing problems, such as the use of on-site environmental equipment for the balance inventory of production line, were found out, and the problems were analyzed to find out the reasons for the existence of the problems. Thirdly, aiming at the current problems of LK company, it proposes targeted improvement plans, and USES the tools of lean production to improve, so as to ensure the safety and order of production environment, ensure the continuity of production, improve the flexibility of the system, and finally achieve the improvement of production efficiency and cost reduction. Finally, from the aspects of team building incentive policy, enterprise culture talent cultivation and other aspects, the guarantee measures for the implementation of lean production method are formulated to ensure the smooth implementation of lean production method.
