This paper presents a new design algorithm for piece-removing dynamical system, based on 6-Sigma DMADOV technique using ARIZ and Brainstorming. Our design target is the piece-removing system installed on a mobile platform of bead-grinding equipment. The 6-Sigma DMADOV technique guides us design process according to 6 steps, i.e., Define - Measure - Analyze - Design - Optimize - Verify. A Design strategy to reduce the weight of piece-removing dynamical system will be explored by using ARIZ, i.e.,(the abbreviation of Algorithm for Inventive Problem Solving in Russian). The ARIZ will result in a final solution that the height and angle control parts for a cutting tool should be replaced by a kinematical approach, rather than complicated mechatronic approach(using motors). The Optimize step is composed of two sub-steps: (i) Generating process for obtaining several ideas of piece-removing system by using Brainstorming technique, satisfying the final solution derived from the Design step using ARIZ, and (ii) Optimizing process for selecting the most optimal idea of piece-removing system by using Pugh's matrix from the viewpoints of weight, cost and accuracy. The laststep of Verify has shown that the final design obtained by the 6-Sigma DMADOV technique with ARIZ & Brainstormingcan improve an initial design with design requirements satisfied. In this paper, we have shown that ARIZ and Brainstorming can be cooperatively merged into 6-Sigma DMADOV to give us both a formulatedproblem-solving approach and diverse candidate solutions(or ideas) without trial-and-error efforts.

Recently the machine industry is rapidly advanced for improving productivity. Especially an effort decreased error factors of machine tool continuously is being studied. In this paper, we propose a method that decreased vibration in the high speed spindle. By appling 6-sigma technique(DMADOV), we can grasp the influence between the housing design and a rotation accuracy. For a correct conclusion, we measure an actual spindle and analysis by $ARMD^{(R)}$(rotation analysis program). inally we find out influenceable design factors and the improvement condition about 20.7%.

System is the organization of hardware, software, personnel and facilities needed to perform a designated function within a stated environment with specified results. The trend of modern systems is getting more complex and larger. The system is necessary for modern society but the minor malfunction of the system can result the enormous human and material losses. Recently it is being heightened the concern for system safety and required to be built and applied Safety Engineering standard Guideline for safety of complex and large-sized system. This paper describes the System Engineering Process model integrated with Safety Engineering and the establishment of standard safety guidelines for safety of product development using DMADOV Methodology of the Lean 6 Sigma.

Information strategy planning (ISP) pursues alignment of business strategy and IT (Information Technology) strategy as well as derivation of feasible and valuable IT projects. However, conventional ISP methodology hardly obtains the objectives because of its intrinsic shortcomings. Diverse ways are proposed for the improvement of the conventional methodology including, for example, combination of EA (Enterprise Architecture) with ISP. Meanwhile, six-sigma methodology which is characterized by quantification, scientific and systematic approach, customer orientation, process orientation has been gaining considerable attention and extending its application scope continuously. In this paper, an innovative ISP methodology is proposed by decomposing activities, methods, and tasks from conventional ISP process and reorganizing them into DMADOV six-sigma framework. In addition, the usefulness and applicability of the newly proposed methodology are provided using an electronics company example. The methodology enhance the possibility of producing future oriented and beneficial IT projects by associating IT strategy and the projects in the form of quantified causal relationship. Besides, it can also increase the objectivity of IT vision and strategy.

TRIZ는 문제분석을 통한 모순을 찾아내어 이를 해결하는 Process에 역점을 두는 방법론으로 알트슐러와 그의 동료에 의해 수십만건의 특허를 분석하는 과정에서 시대와 분야를 막론하고 동일한 유형의 문제가 반복되고, 이를 해결하는 방법도 동일함을 규명하여 이를 체계화한 방법론으로, 현재 핵심기술 개발 및 창의적 문제 해결 방법론으로 각광받고 있다. 그러나 TRIZ 역시 문제점을 가지고 있으며, 그것은 초기 과제 정의가 어렵다는 것과 효과산출을 어떻게 하면 객관화 할 수 있을 것인가 이며, 또한 도출된 아이디어를 최적화 하는 방안이다 하나의 방법론만으로는 모든 과제 해결을 위해 일괄 적용 시키는 것은 모순이며, 경영기법간의 연계를 통한 경영효과 극대화가 필요하다. 이 논문에서는 6시그마와 TRIZ 방법론 분석을 통한 각 방법론의 이해를 높이고, 이를 바탕으로 서로 방법론간의 연계의 필요성을 확인 및 방법론 간 연계를 위한 연계 프로세스 모델을 제시하고자 한다.

많은 조직들이 정보화 전략계획(Information Strategy Planning: ISP)을 수립하고 있지만 ISP의 주요한 추진목적인 경영전략과 IT 전략의 연계와 기업의 가치창출에 직접적으로 기여할 수 있는 정보 시스템 구축과제의 도출이 미흡하여 그 결과물들이 단지 계획에 그쳐버리고 실행으로 연결되지 못하는 경우가 많아 ISP 무용론이 팽배한 실정이다. 한편, 6시그마 방법론이 데이터에 근거한 체계적이고 과학적인 강력한 방법론으로 대두되고 있으며 최근 그 적용영역을 지속적으로 넓혀나가고 있다. 본 논문의 목적은 전통적인 정보화 전략 수립프로세스를 분해하여 얻어지는 활동과 기법 그리고 과업들을 6시그마의 DMADOV 표준 프로세스에 맞게 재조합하여 새로운 방법론을 도출하는 것이다. 본 방법론을 활용함으로써 정보화 전략수립 과정에서 성과지향적인 정보화 과제도출의 가능성을 높이고 방법론의 계량화를 통해 제시된 결과들의 객관성을 높일 수 있다.

A high speed automated pitch variation unit (HAPU) related to semiconductor category sorting movement of the test handler system was developed. In the design process, 'DMADOV' step of 6-Sigma method has been applied. The design result for the desirable pitch variation was a 3:1 reduction rack-pinion and a linkage which are operated by servomotors. The realization and reliability of the mechanism was obtained at the design stage by FEM analysis, and by robust design using Taguchi orthogonal array against weight and deformation. Finally, the validity of the high speed variation mechanism was confirmed via inspection using a high speed camera while performing pitch variation.
