An alternator which converts mechanical rotating energy into electric energy is an important component of a vehicle. It operates in broad range from 3000 RPM to 18000 RPM. So, sufficient flow rate and low noise are needed in such broad operating range for a cooling fan of this alternator. In current study, the cooling fan of an alternator is developed through DFSS process and numerical analysis. In order to calculate flow rate and noise level, SC/Tetra and FlowNoise S/W are used respectively, for a new developed fan, compared with original model, numerical result shows 3 dBA reduction and measured value shows 4 dBA reduction.

In pursuit of decreasing noise and vibration, the electromagnetic active control mount(ACM) is developed which is corresponding with the tendency of greater fuel efficiency, higher engine power and lower lightweight vehicle. In process of developing the ACM, making patent searches and benchmarking are performed first, and then robust mount design which is reflected on the users' demand through Design For Six Sigma(DFSS) is carried out. The manufactured prototype of ACM is tested in various environmental conditions for the purpose of ensuring the performance quantitatively.

최적의 혁신기법이란 각사의 핵심역량을 명확히 한 후 꾸준히 그리고 지속적으로 자사에 맞게 시스템(SYSTEM)을 변형해 나가는 과정에서 완성된다고 볼 수 있다. 반도체 제조사인 H사는 지난 IMF 때 경영적인 어려움을 극복하고 최근 각 부문(제조, 연구개발, 영업 등)의 탁월한 경영성과를 올리고 있다. 이러한 성과를 뒷받침하는 것은 경영혁신 활동이 일환으로 TPM을 2001년부터 꾸준하게 적용을 해 오고 있다는 것이다. 일반적으로 TPM은 제조중심의 활동이 대부분이나, H사는 R&D부문 경영혁신 활동에 TPM활동을 접목해 활동을 하고 있다. 본 연구는 H사의 R&D부문 TPM R&D보전의 10대 지주 활동과 연구개발 부문에서 활발하게 연구되고 있는 Lean DFSS의 두 방법론에의 장 ${\cdot}$ 단점을 분석하여 좀 더 바람직한 방법론을 연구해 볼 필요가 있다.

Ten years have passed since Samsung SDI and LG Electronics introduced six sigma. Six sigma spreads on the wide industry areas such as service and public sectors as well as manufacturing industry. Six sigma speaks for Korean enterprise's management innovation now. Then, can we evaluate that Korean enterprise's six sigma has settled down successfully? This study compares Korean enterprise's six sigma with those of Japanese and American enterprises in the view of leadership, project, people, and methodology. We suggest five topics for the successful settlement of six sigma in Korean enterprises; 1) Role of executives and managers should be changed more actively, 2) Strategy-connected projects should be excavated, 3) Utilization and development plan should be made for black belt and master black belt, 4) Six sigma methodology should be advanced, especially DFSS methodology, and finally 5) Several innovation methodology should be integrated.

많은 6시그마 혁신을 하는 기업 중에서 IS09000 시리즈나 IS0/TS16949 인증을 받고 있다. 그럼에도 불구하고 6시그마 도입 초기부터 ISO/TS16949와 통합운영을 생각하고 추진하는 곳은 많지 않다. ISO/TS16949에서는 기업전반의 프로세스에 많은 중점을 두고 있다. 그 중에서도 APQP(Advanced Product Quality Planning)은 제품 초기에서 부터 명확한 품질계획 업무 프로세스를 가지고 활동을 하라는 필수 프로세스를 요구하고 있다. 그러나 구체적인 Flow나 단계는 각 기업체의 특성에 맞기고 있다. 6시그마의 Lean DFSS는 이러한 제품개발 프로세스의 구체적인 전개단계를 제공 하고 있다. 여기에 APQP에 서 요건으로 명시한 각 프로세스 단계마다 인풋(Input)요소, 아웃풋(Output) 요소, 타켓(Target), 그 프로세스를 책임질 구성원, 핵심성공요인(KSF), 핵심성공지수(KPI), 단계마다의 FMEA(Failure Mode Effect Analysis) 분석을 대응하면 도입 초기에서 부터 상호 유기적이면서 효과적인 System이 된다.

This paper relates to the automotive silencers reduce noise generated from the actual vehicle for the activity is based on was worth. To do this, the noise from cars to distinguish them by category, characteristics of turbo charger was designed to reduce noise. In order for the design of acoustic modeling using line dynamics, was analyzed using In house & the commercial software programs. Silencers have about several basic elements. Expand, collapse, perforated plate, and the combination are the basic reactive or dissipative elements. Finally, DFSS(design for six sigma) method was designed. and it was verified in vehicle test. The new developed silencers showed good performance vehicle test results. also, the net cost also indicated excellent results compared with other company.

New design of catalytic converter is proposed by optimization of DFSS (Design For Six Sigma) and DOE (Design Of Experiment) method which is based on taguchi matrix. As a result of the optimization of design of catalytic converter, this paper classifies Exhaust-downpipe shapes with 3 parameters to increase flow velocity uniformity of front catalytic substrate face from CFD results. after finishing with L9 Taguchi test matrix, it can be found the main effect of each design parameter of concept model, and optimal design level. in conclusion, it can be increase flow uniformity from 0.60 upto 0.80 with optimal diffuser shape for Turbo-charger.

많은 정보시스템 개발 프로젝트가 고객의 요구를 정확히 반영하지 못한 이유 때문에 실패하거나 설계변경 등의 다양한 문제를 발생 시키고 있다. 실패의 궁극적인 원인은 고객 가치 중심의 요구사항 재정의에 실패 한데에 있다. 이러한 문제점을 해결하기 위해서는 기존 시스템에 새로운 가치를 부여하여 기존고객 뿐만 아니라 새로운 고객까지 만족 시킴으로써 경쟁이 없는 시장 공간을 창출하는 것이 가장 효과적인 방법이다. 본 논문에서는 이러한 문제점을 해결하기 위하여, 블루오션 전략 프레임워크의 핵심인 ERRC(Erasure Reduce Raise Create) 분석 방법을 적용하여 고객가치를 창출할 수 있는 블루오션 요구공학 프로세스를 제안하였다. 또한, 정량적이고 체계적인 분석을 위하여 DFSS(Design For Six Sigma) 방법론을 적용하고, 제안된 접근법을 실제 정보시스템 개발 시 적용한 사례를 제시하고 적용결과의 유효성을 검증하기 위해 시스템 사용자에 대한 실증 분석결과를 제시하였다.

The quality improvement methodology Six Sigma gained enormous international popularity in the past few years, mainly due to its successful implementation at General Electric. Six Sigma is now commonly understood not only as a statistical measure for process performance (6$\sigma$ stands for 3.4 defects per million opportunities) to improve product quality but it has also become a strategic initiative undertaken by many organisations to improve management quality. In the centre of the Six Sigma methodology is the improvement project, often referred to as Black Belt or Green Belt project. Although every business is different and business priorities differ from company to company, however all businesses face the same problem when it comes to Six Sigma projects: How to choose the right project\ulcorner This article intends to provide some answers to this and other frequently asked questions about Six Sigma projects.

In this paper, we introduce MTS(Mahalanobis-Taguchi System) Method which is suggested Dr. Taguchi in later 1990. We apply MTS Method for Quality Competitive Appraisal System(QCAS) Model which is executived from 1997 by Agency for Technology and Standards, Ministry of Commerce, Industry and Energy(MOCIE). We can measure company Quality competitive by using MTS. MTS Measure can not be compared statistical sum by calculated QCAS. MTS can be possible distinct subtle which can not distinct using statistical sum. Also MTS Method can seek more strong effect factor among of many factor. If A Company use MTS Method, can find vital factor and level of destination.
