【摘要】 随着经济全球化与一体化趋势的不断增强,很多企业在面临国内市场竞争的同时,还要面对来自国外市场的竞争,甚至还有其他不同行业的不对称竞争。因此企业如果不能做好新产品开发,进而做出更有竞争力的产品,那么很有可能在激烈的竞争中被淘汰出局。为了能够赢得市场,在竞争中谋生存、求发展,企业迫切需要提升研发质量与产品质量,压缩产品从研发到量产的时间。以最优质的产品与服务来满足客户的需求才能赢得客户的信任。本文首先讲述了六西格玛管理以及六西格玛设计的相关理论及其国内外研究现状。然后以B公司的新产品研发为研究对象,针对研发过程中出现的研发质量问题导致的产品质量不达标、研发周期长的问题进行实例分析,找到问题的产生原因,并提出了以六西格玛设计为方法的解决方案。在解决方案的实施过程中,按照识别(Identify)、定义(Define)、设计(Design)、优化(Optimize)、验证(Verify)简称IDDOV的流程成立六西格玛设计团队,分析客户需求,针对关键的质量指标运用公差分析,可制造性设计(Design for Manufacturability,简称DFM)等工具得出合理的相关设计数据。然后通过实验设计(Design of experiment简称DOE)的方法,找到合理的工艺参数进行生产制造,从而使得产品达到了六西格玛质量水平。最后通过改进前后的对比,确认了研发的质量有明显的提升、研发的周期也大幅缩短。本文中的研究为B公司的研发能力提升找到了有效的解决方案。通过六西格玛设计方案的实施,保证了项目顺利完成,降低了研发成本,提升了研发质量。从而提高了客户满意度以及公司的核心竞争力。也进一步扩大了公司的知名度与影响力。本文的研究对该行业的其它公司也有一定的借鉴与指导意义。尤其是一些规模不是很大的公司缺乏系统的流程与方法,以前往往有一种认知的误区,即引入六西格玛设计会导致工作效率的下降以及成本的浪费。而通过本文的实例研究恰恰证明了实施六西格玛设计是可以提升效率,降低成本的。因此,六西格玛设计方案的普遍应用也将会提高国内原始设计制造商(Original design Manufacture,简称ODM)的行业竞争力,进而促进整个行业的发展。更多还原

【Abstract】 Economic globalization and economic integration have become trend in current world.As the continuous enhancement of this trend,many enterprises have to face not only domestic market competition,also competition from international markets,and even asymmetric competition in other different industries.Therefore,if enterprises cannot do a good job on new products development,and provide more competitive products,they are likely to be eliminated in the fierce competition.In order to win the market,survive and develop in the competition,enterprises urgently need to improve the quality of research and development,reduce the time from development to mass production.As long as we meet the requirements of customers with the best quality of products and services,the customers will give us more trust.This thesis first describes the relevant theory of Six Sigma and its current research status at home and abroad.Then taking the new product research and development of Company B as the research object,we analyzed the root cause of low product quality and long development cycle.We took Six Sigma design as the method.During the implementation,we established a Six Sigma design team to analyze customer requirements as the process of Identify,Define,Design,Optimize and Verify.Shorten to IDDOV.Using tolerance analysis for key parameter,Design for Manufacturability design(DFM)and other tools are used to obtain reasonable relevant design data.Then,the reasonable process parameters are found out as Design of experiment(DOE)method.So the product quality reaches the six Sigma level.Finally,through the comparison between before application and after application,it is confirmed that the quality of development has been significantly improved,and the development cycle also has been greatly shortened.We have found an effective solution for improving R & D capabilities of company based the research in this thesis.By the implementation of the six Sigma design,the smooth completion of the project is guaranteed,the research and development cost is reduced,and the research and development quality is improved.Thus improving customer satisfaction and the company’s core competitiveness.This has enhanced the popularity and influence power of the company.The research also has certain reference and guiding significance for other companies in the industry.In particular,some companies,which are not very large scale,lack systematic processes and methods.There is often a cognitive misunderstanding that the application of six sigma design will lead to a decline in work efficiency and it is a waste of cost.This research just proves that the implementation of Six Sigma design can improve work efficiency and reduce cost.Therefore,the general application of the Six Sigma design scheme will also improve the competitiveness of domestic ODM companies in the industry,and then promote the development of the whole industry.更多还原
