Ser-M 모델에 기초한 6시그마 발전단계에 대한 고찰
김동준(Dong-chun Kim),임호순(Ho-sun Rhim) 한국구매조달학회 2008 한국구매조달학회지 Vol.7 No.1
최근 급변하는 시장 상황에 맞서, 6시그마 경영전략도 진화해 나가고 있다. 초기 Motorola에 의거 시작된 6시그마가 품질 우위의 Product 경쟁력 강화에 초점을 맞추었다면, GE에 의해 주도된 6시그마는 비용절감을 위한 프로세스 경쟁력 향상에 치중하였다고 볼 수 있으며, 현재는 고객 관점에서 가치 창출을 위한 경영전략으로서 발전해 가고 있다. 본 논문에서는 ‘ser-M’ 모델을 이용하여, 기업 메커니즘을 구성하고 있는 각 요인들, 즉 기업의 주체(subject), 당면한 환경(environment), 새롭게 축적한 자원(resource), 그리고 기업의 주체가 이들 환경과 자원을 결합시켜 성과를 달성하는 방법론(mechanism)의 4가지 관점에서 6시그마 추진 성공요인을 살펴보고, 6시그마 경영전략의 전개 방향에 대하여 논한다. There is no doubt that the Six Sigma is powerful to improve quality, reduce cost and product development time, and achieve major competitive market advantages. In this paper, success factors for Six Sigma deployment are considered from subject, environment, resource, mechanism point of views, which are based on ‘ser-M’ model. The next generation of Six Sigma is discussed with cases of GE, Motorola, and Samsung SDI. The next generation of Six Sigma will: 1) provide a world-class innovative business strategy, 2) encourage a common vision, as a common language shared by all, and 3) combine stretch goals associated with better, faster, lower cost products and services with any of the many possible methodologies such as lean principle and theory of constraints.

Global regulatory pressures relating climate change and environmental responsibility are asking companies to find out the best way for sustaining their continuous business growths. It could be known that inadequate management for environmental issues are bad for business, negatively affecting brand image, causing unnecessary losses and costs for environmental preservation. For this reason, environmentally conscious green business growth has been recognized as an essential requirement for a company to stay in business. Many companies are looking for green business opportunities of improving their environmental and financial results, and struggling with how green fits into their business. In this paper, the Green Six Sigma, an environmentally conscious Six Sigma methodology, is presented as a way to find solutions for green growths. The Six Sigma is known as a disciplined, data-driven approach and methodology for achieving world-class performance in any process from manufacturing to transactional. In chronological order, the Six Sigma has been evolved from Motorola`s quality-oriented methodology to GE`s cost-oriented lean approach, and is being evolved and developed as an environment-oriented green growth approach. There is no doubt that the Green Six Sigma, as an engine of green growth, is a power tool for achieving competitive business performance and reducing the impact on the environment.
1MW급 조류발전기 모듈화 및 유체베어링 설계적용 검토
방덕제(Deok-je Bang),김동준(Dong-Jun Kim),오진안(Jin-An Oh),한필완(Pil-Wan Han),전연도(Yeon-Do Chun) 한국해양환경·에너지학회 2021 한국해양환경공학회 학술대회논문집 Vol.2021 No.10
본 논문에서는 1MW급 직접구동방식 영구자석형 조류발전기의 가격, 유지보수, 가동률 및 신뢰성 측면에서 경쟁력을 높일 수 있는 복수모듈형 회전자 구조와 유체베어링 적용을 검토한다. 복수개의 모듈로 구성된 회전자 구조는 제작, 조립, 취급, 수송, 설치, 유지보수에 용이하며, 유체베어링은 운전시에 기계적 접촉이 제거되어 베어링의 수명과 신뢰성 향상이 가능하게 된다. In this paper, a rotor configured with a plural module combination structure and a hydraulic bearing are represented in order to enhance the competitiveness in terms of price, maintenance, availability and reliability of 1MW direct-drive permanent magnet tidal generator. The rotor structure constructed with plural modules is easy to manufacture, assemble, handle, transport, install, and maintain, and the hydraulic bearings can remove the mechanical contact in between the rotor and the stator of the generator, thereby improving the lifespan and reliability of the bearing.

The need to reduce time from concept design to production in the automotive industry is spreading far and wide for staying in a competitive market. To cope with the increasing requirement for short development time, full vehicle model for the multi-dynamics simuation has been constructed with the control logics of suspension and brake systems. To improve the design quality while significantly shortening the design cycle in the development of a new vehicle, Vehicle Dynamics Simulation(VDS) have been performed for verifying and modifying the design of automotive components used in the suspension, steering and brake systems. Various simulations have been carried out, using ADAMS which is a commercial code for multi-dynamics simulation. Particularly, the control logic for suspension system is adapted with the Sky-hook algorithm. For the evaluations of vehicle characteristics such as a ride and handling, the control logics used in suspension and brake systems are compared and evaluated with the simulation results. It is anticipated that the simulation techniques suggested will be a promising tool for reducing time significantly from concept design to production in the automotive industry.<br/>
