정보공학 시스템 개발 방법론 기반 QCD분석 방안에 관한 연구
전홍배 ( Hong Bae Jun ),서효원 ( Hyo Won Suh ) LGCNS 엔트루정보기술연구소 2009 Entrue Journal of Information Technology Vol.8 No.2
시스템 개발 방법론이란 시스템 개발 시 시스템을 분석, 설계, 구축 및 유지 보수하는데 있어서 사용자 및 개발자에게 시스템 개발에 대한 가이드를 제시하는 틀을 말하며 QCD분석이란 시스템의 수준을 품질(Quality), 비용(Cost), 납기(Delivery) 측면에서 정량화시켜 분석하는 것을 말한다. 시스템 개발 시 시스템 개발방법론과 같이 연동되어 도출되는 개발 산출물들이 나중에 어떤 성능을 보이는지 파악해 볼 수 있는 분석절차가 있어야 개발 목표에 부합되는 시스템이 구축되어질 수 있도록 관리할 수 있다. 본 연구에서는 중소형 CIM 구축 작업에 정보공학 시스템 개발 방법론을 적용함에 있어서 방법론 산출물을 기반으로 하여 시스템의 수준을 측정, 시스템 설계에 반영하는 시스템 개발 방법론 기반 QCD분석 절차를 제시하고자 한다. This paper introduces a framework for QCD(Quality, Cost and Delivery) analysis based on the information engineering system development methodology. In general, during developing a complex system, the system development methodology is used for guiding system design, analysis and implementation in a systematic way. However, previous development methodologies have the limitation in managing the performance of system development in a consistent way. To cope with this limitation, in this study, we have proposed how to manage the performance of system during system development processes in terms of QCD. The proposed method has been applied in the information system development for a small and medium size enterprise in Korea.

저탄소 도시관리를 위한 도시공간조직의 재구조화 과정에 관한 연구
염인섭(Yeom, In-Sup),오덕성(Oh, Deog-Seong) 대한건축학회 2014 대한건축학회논문집 Vol.30 No.2
This paper aims to identify the relationship and relative importance of the elements in a Green City planning, which are based on the spatial restructuring for qualities of urban form such as accessibility, efficiency, viability, security and amenity and the physical restructuring of the fabric and metabolism at various scale of urban system. What we find is that the linkage between quality of spaces in urban form and its planning elements (of a Green City) are generally complex and indirect. With these considerations, we find out the planning directions and practical lessons through pairwise comparison matrix of "quality of spaces (Q)" and "planning elements(G)" using the AHP(Analytic Hierarchy Process). Also, this paper describes how to define impact on restructuring of urban system by connection between quality based goals-quality of spaces (Q), strategy planning-planning elements (G) and performance indicator-planning indicator (T) in urban system by applying QFD(Quality Function Deployment) methodology. The analysis in this paper is completed by the following processes: i) extracting major components on quality of spaces(Q) the planning elements(G), ii) understanding the co-operative relationship or effects between them, iii) analyzing the relative importance of planning elements with relation to quality of spaces, iv) and then determining the impact on planning elements by performance indicator in relation to quality of spaces implicated in urban system. It thus draws implications for spatial and physical restructuring of urban system at various scale in the planning process for a Green City. Finally, it is very important for an urban system as an engine of a city to be tuned or re-engineered for greater efficiency with good match or linkage between planning elements in relation to its qualities of urban space.
