Research On Improving Production Line Efficiency Of TS Company Based On Lean Management Theory

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.This thesis studies the efficiency improvement of TS Company’s production line from the "5m" dimension.This thesis forms a complete lean improvement scheme for efficiency improvement to solve the difficulties of TS Company’s manufacturing system.In this thesis,the effect of the scheme provided is verified by implementing and tracking the schemes in various dimensions.At the same time,the effect of the efficiency improvement results is evaluated with two key efficiency indicators JPH（output per unit time）and HPV（single manufacturing man hour）,and the curing method of hierarchical audit is proposed.Finally,it verifies the feasibility and effectiveness of the efficiency improvement scheme designed in this thesis in TS Company’s manufacturing system,and finally helps enterprises optimize delivery,quality and cost.
