Research On Application Of Lean Six Sigma Management In Speaker Production Of AOI Company

Lean Six Sigma is an advanced management method,which combines lean production and six Sigma management advantages,and solves the shortcomings of any single mode thoroughly through complementary advantages.Toyota Motor Company of Japan is the founder of lean production that solves bottleneck of processes to achieve quicker speed of production and waste elimination.Motorola is where Six Sigma began and the focus is product quality,six sigma improves the quality by optimization of production processes.Both lean production and six sigma alone can achieve amazing results,however,due to the different focus of them,using one method alone cannot take account of the quality and speed.With the increasingly fierce market competition,in order to balance quality and speed,it is an inevitable trend for enterprises,especially manufacturing enterprises to apply Lean Six Sigma.Lean Six Sigma management is gradually integrated into the strategic management of outstanding companies,with the aim of improving customer satisfaction and saving operation costs to achieve outstanding performance.However,most of the implementation of Lean Six Sigma management tends to be formalized,and few enterprises can truly realize continuous improvement and management reform.It is a common problem for enterprises to truly apply the advantages of Lean Six Sigma management to maximize the actual benefits.This thesis takes AOI company as the case study project.Firstly,it introduces the current situation and production management status of AOI company,through in-depth analysis,it is found that the company existed high rate of defective products,imbalanced production and serious waste as well as the high customer complaint rates etc.,it also verifies the feasibility of introducing lean six sigma from the aspects of existing ERP system,human resources and others.Secondly,this paper carries out Lean Six Sigma design for loudspeaker production from five aspects:definition,measurement,analysis,improvement and control to solve the problems in the loudspeaker production management,Finally,it verifies the effectiveness of the improvements through before and after implementation comparison.The research can not only help AOI company to establish a lean six sigma management framework to solve the existing problems,but also provide a certain reference value for other manufacturing enterprises for introducing lean six sigma management.
