정보시스템의 개발에 있어서 요구사항의 체계적인 관리가 중요시되는 가운데, 요구사항에 대한 세부적인 정보들을 계량적으로 관리하기 위한 체계적인 분류방법이 부족한 것으로 판단되어, 요구사항을 업무로직, 데이터, 기술기반 관점 및 CEO/CIO, 책임자, 설계자 시각에 따른 요구사항 분류매트릭스를 제공함으로써, 요구사항을 좀더 체계적으로 수집, 관리할 수 있는 기반을 마련하였다.

As software grows continuously in scale and complexity, the role of software architecture has become increasingly important across various industries. Although software architects often rely on their experience and intuition when designing such architecture, there is a variety of methodologies being researched for architecture design. However, these methodologies do not address the specific effects of applying multiple architectural patterns to a system or the sequence in which they should be applied. In this study, we explain the variation in architectural design results depending on the order in which the same set of architectural patterns is applied to a single system. Based on this phenomenon, we identify requirements for applying architectural patterns and propose a method of classifying the patterns to be applied. We also propose a prioritization process for requirements to efficiently apply the classified patterns in a specific order. Finally, we show a case study that prioritizing requirements based on architectural pattern types is beneficial for efficient software architecture design in terms of quality attributes.

Defects are an important factor in the quality of software developments. In order to manage defects, we propose additional information of search and classification. Additional information suggests a systematic classification scheme and method of operation. In this study, we propose additional information at the requirements analysis stage for defect management.

In order for a classification system to be useful in every day business environments, it has to reflect peculiar characteristics of enterprises and organizations. By automating the generation process of classification, the overall operation of classification system becomes effective and efficient. However, in order for it to be really useful, human input and interventions are needed from the very beginning phase of the classification generation. This paper proposes an user-guided classification generation algorithm, in which the user inputs a specific level of the classification that she/he wants. Also we propose and implement manipulation operators to tailor the initial classification into the shape that user wants.

A product classification scheme is the foundation on which product databases are designed, and plays a central role in almost all aspects of management and use of product information. It needs to meet diverse user views to support efficient and convenient use of product information. It needs to be changed and evolved very often without breaking consistency in the cases of introduction of new products, extinction of existing products, class reorganization, and class specialization. It also needs to be merged and mapped with other classification schemes without information loss when B2B transactions occur. For these requirements, a classification scheme should be so dynamic that it takes in them within right time and cost. The existing classification schemes widely used today such as UNSPSC and eCl@ss, however, have a lot of limitations to meet these requirements for dynamic features of classification. Product information implies a plenty of semantics such as class attributes like material, time, place, etc., and integrity constraints. In this Paper, we analyze the dynamic features of product databases and the limitation of existing code based classification schemes, and describe the semantic classification model proposed in [1], which satisfies the requirements for dynamic features of product databases. It provides a means to explicitly and formally express more semantics for product classes and organizes class relationships into a graph.

본 연구에서는 위성영상 상황판연계·표출시스템을 개발하기 위하여 사용자 요구사항을 조사 및 분석하였고 분석 결과, 요구사항정의서와 시스템규격서를 도출하였다. 먼저, 위성영상 상황판 연계·표출시스템의 요구사항 조사를 위해 중앙재난안전상황실 근무자를 대상으로 설문(수요) 조사를 수행하였다. 상황실 실무자별 요구사항을 취합한 설문 결과와 연구 1차년에 수행했던 상황실 근무자 인터뷰 결과, RFP, 연구단 내부협의 결과를 검토하여 정보제공 측면 및 위성영상 활용 측면의 사용자 요구사항을 도출하였다. 도출 결과를 기반으로 시스템 요구사항을 정의한 결과, 시스템 기능은 54개의 기능과 9개의 비기능으로 분류되었다. 또한, 시스템 구성요소별 요구기능을 세부적으로 구분하여 요구사항정의서를 작성하였다. 시스템 요구기능 분류는 사용자기능/관리자기능/사용자서비스/사용자인터페이스/시스템기능/시스템서비스 등으로 상세 구분하였다. 마지막으로, 연구단 협의를 통해 요구사항정의서를 기반의 시스템규격서를 작성하였다. 시스템규격서는 일반규격, 각 시스템별 성능규격, 인터페이스규격, 기능규격으로 구분하여 세부 정의하였다. 본 연구내용은 지속적인 연구 개발을 통해 위성영상 상황판연계·표출시스템 설계 자료로 활용될 계획이며, 향후 위성영상을 활용한 재난안전 상황관리 대비/대응 체계 마련에 도움을 줄 것으로 사료된다.

This paper is about that case study of the Tube Transportation System that the new transportation system offering passenger and logistic service in a metropolis having plenty of the floating population or between medium-sized cities, and solving large issues like terrible traffic jams and environmental problems etc. in this region. Also it presented that elicitation results of performance parameter and the categorization system of it applying a systematic analysis methodology. By the medium of this paper, It showed that definition, case study, performance parameters, and the categorization system of parameters of a general tube transportation system before developing requirements of a specific tube transportation system. From now on, it will come in pretty handy in systems engineering of activities to establish a concept of a new tube transportation systems and develop requirements.

Electronic catalogs (or e-catalogs) hold information about the goods and services offered or requested by the participants, and consequently, form the basis of an e-commerce transaction. Catalog management is complicated by a number of factors and product classification is at the core of these issues. Classification hierarchy is used for spend analysis, custom3 regulation, and product identification. Classification is the foundation on which product databases are designed, and plays a central role in almost all aspects of management and use of product information. However, product classification has received little formal treatment in terms of underlying model, operations, and semantics. We believe that the lack of a logical model for classification Introduces a number of problems not only for the classification itself but also for the product database in general. It needs to meet diverse user views to support efficient and convenient use of product information. It needs to be changed and evolved very often without breaking consistency in the cases of introduction of new products, extinction of existing products, class reorganization, and class specialization. It also needs to be merged and mapped with other classification schemes without information loss when B2B transactions occur. For these requirements, a classification scheme should be so dynamic that it takes in them within right time and cost. The existing classification schemes widely used today such as UNSPSC and eClass, however, have a lot of limitations to meet these requirements for dynamic features of classification. In this paper, we try to understand what it means to classify products and present how best to represent classification schemes so as to capture the semantics behind the classifications and facilitate mappings between them. Product information implies a plenty of semantics such as class attributes like material, time, place, etc., and integrity constraints. In this paper, we analyze the dynamic features of product databases and the limitation of existing code based classification schemes. And describe the semantic classification model, which satisfies the requirements for dynamic features oi product databases. It provides a means to explicitly and formally express more semantics for product classes and organizes class relationships into a graph. We believe the model proposed in this paper satisfies the requirements and challenges that have been raised by previous works.

토목구조물의 설계 패러다임이 2차원에서 3차원으로 전환될 때 효율성과 재활용성의 관건이 되는 기술적 제약사항이 호환성이다. 대부분의 캐드 엔진이 형상모델 수준에서 호환성 혹은 연계성을 지원하고 있지만 3차원 정보모델에서 요구하는 정보모델의 호환성은 지원하고 있지 않은 실정이다. 이 논문에서는 콘크리트 박스 교량에 대해서 3차원 교량 정보 모델을 구성하고 건설 프로세서에서 이를 활용할 수 있는 방안을 시범적으로 적용한 사례를 정리하였다. 적용 대상 구조물은 FSM 공법으로 시공되는 경간 40미터의 콘크리트 박스거더 교량이다. 견적, 시공시뮬레이션, 해석 등의 프로세서의 요구사항을 반영한 분류체계에 따라 형상모델의 체계를 정의하고 각각의 형상모델 단위에 정보를 부여하는 방식을 사용하였다. 개별 프로세서를 위한 솔류션에서 이러한 형상과 정보가 연계된 내용을 받아들이거나 캐드 엔진에서 필요한 형태로 내보내는 방식을 모두 시도하였다. 3차원 형상 모델과 시간이 부여된 4D 시뮬레이션을 활용하여 공사 스케쥴에 따라 모델 레이어 분류 작업으로 공사 진행 단계가 가상으로 보여진다. 시범 적용을 통해서 가상건설 시스템의 구성하는 개별 솔류션 혹은 정보체계에 대한 문제점과 개선사항을 도출하였다.
