Application Research On Assembly Line Of Concrete Mixing Truck Based On Lean Six Sigma

Production management method of Lean Six Sigma is currently manufacturing enterprises to reduce production cost,improve production efficiency,improve the effective management method is one of the important quality of products,enterprises can change the concept of operations,reshaping the corporate culture,enhance the competitiveness of enterprises,and bring huge economic and social benefits.SWY company completed the new production base put into operation in 2013,for SWY,how in the new production base of production and operation in the scientific use of Lean Six Sigma tools and techniques,optimization of process route,eliminate all kinds of waste,production and assembly in improving the status of the existing assembly line,strengthen site management,improve the production efficiency.The company is an important issue urgent.This paper first makes a detailed review of lean and Six Sigma Application Statu s and development history and solve the problem of its advantages and disadvantages;then introduces the combination of lean and Six Sigma Lean Six Sigma Theory of concept formation,and the implementation of process management based on Lean Six Sigma(DMAIC)and common tools etc.in detail;the last company to SWY concrete mixing truck assembly line as the research object,the specific practice of DMAIC implementation process based on the assembly line,to solve the existing problems,makes the assembling rhythm is significantly reduced,the product quality and production efficiency improvement of.In addition,the investigation and Analysis on the concrete mixing truck products customer demand,put forward the measure to measure the concrete mixing truck assembly line project implementation of lean six sigma.Further evaluate project risk,calculate expected revenue and set up project team.In the process of DMAIC implementation process using the SIPOC analysis and measurement system(MSA),FMEA(Failure causal matrix,Mode & Effect Analysis)analysis and MINTAB software,Platon hypothesis test and scatter diagram,single valued graph,line graph control box analysis tools and methods based on the analysis of all the problems are specific the quantitative improvement process and effect has been effectively controlled,and to evaluate the effect of each stage of the analysis,reached the expected target.Finally,this paper summarizes and analyzes the achievements of the implementation of Lean Six Sigma project.By summing up the successful experience and shortcomings of the concrete mixing truck assembly line of the implementation o f Lean Six Sigma in the process,the implementation of the project effective methods and processes,provides some experience and knowledge accumulation for Lean Six Sigma management mode is the new production base in SWY,the same type of production line full implementation.
