소프트웨어 개발공정 상의 요구사항 문서적 분석에 치중되어 있던 요구사항 분석에 관한 논의는 기업 통합을 더욱 효과적으로 하기 위해 소프트웨어적 차원을 넘어 기업 아키텍처 기반의 정보시스템 개발 및 통합의 필요성에 대한 논의로 확대되고 있다. 본 연구에서는 궁극적으로 기업 아키텍처의 효과적인 수립을 지원하는 요구사항 분석, 관리 프레임 웍과 분석 프로세스를 제시한다. 요구사항 분석 프로세스는 기업 아키텍처의 개념을 바탕으로 다양한 사용자와 관점이 구별하고, 이를 다시 요구사항 추출을 위해 업무적 관점과 정보시스템 관점으로 구분한다. 이러한 요구사항 분석을 위한 프로세스는 기업 아키텍처의 수립을 효율적으로 지원할 것이다.

Bandwidth Trading(BT) represents a potential market with over 1 trillion USD across the world and high growth potential. BT is also likely to accelerate globalization of the telecommunications industry and massive restructuring driven by unbundling rush. However, systematic researches on BT remain at an infant stage. This study starts with structure analysis of the Internet industry, and discusses significance of Internet interconnection with respect to BT issues. We also describe the bandwidth commoditization trends and review technical requirements for effective Internet interconnection with BT capability. Taking a step further, this study explores the possibility of improving efficiency of network providers and increasing user convenience by developing an architectural prototype of Hub-&-Spoke interconnection model required to facilitate BT. The BT market provides an innovative base to ease rigidity of two-party contract and increase service efficiency. However, as fair, efficient operation by third party is required, this research finally proposes an exchanging hub named NIBX(New Internet Business eXchange).

모든 컴포넌트가 개발된 후에 테스트를 시행하는 것은 프로젝트의 위험을 증대 시킨다. 프로젝트 개발 주기상 나중에 파악된 에러에 대한 조치는 매우 어렵고, 전체 프로젝트 일정을 연기하는 주원인이 된다. 특히, 아키텍처에 문제가 있는 경우에는 전체 시스템에 대한 재설계가 요구되기도 한다.(중략)

There have been various attempts of Knowledge Management System in order to effectively support Knowledge Process and to manage a wide variety of unstructured knowledge. However, Knowledge Management System basically has some significant weakness for searching knowledge, extracting information and maintenance, and some difficulties to integrate such various knowledge resources. Several studies had been conducted to overcome these weaknesses and to improve the method of knowledge management. The purpose of this study is 1) to examine the effectiveness of Semantic Web Technology that has a great attention lately; whether it is useful to overcome the weaknesses, and 2) to review its strong points and some future uses. Further, differences of Semantic Web Technology compared to existing Knowledge Management System Architecture are reviewed. Finally, a new Semantic Web Enabled KMS Architecture is proposed. Also some prospects for future market direction are suggested.

In this paper, we introduce a new combinatorial auction mechanism - N-Bilateral Optimized Combinatorial Auction (N-BOCA). N-BOCA is a flexible iterative combinatorial auction model that offers optimized trading for multi-suppliers and multi-purchasers in the supply chain. We design the N-BOCA system from the perspectives of architecture, protocol, and trading strategy. Under the given N-BOCA architecture and protocol, auctioneers and bidders have diverse decision strategies f3r winner determination. This needs flexible modeling environments. Hence, we propose an optimization modeling agent for bid and auctioneer selection. The agent has the capability to automatic model formulation for Integer Programming modeling. Finally, we show the viability of N-BOCA through prototype and experiments. The results say both higher allocation efficiency and effectiveness compared with 1-to-N general combinatorial auction mechanisms.

To reduce time to market for converged services, the service provider needs to combine external services and internal processes together, and IT architecture for converged services has to support it. Service Oriented Architecture (SOA) enables the development of a converged service by combining external services and internal processes effectively. However, it is difficult for the existing SOA methods to support the evolution of a converged service, even though the service which consists of the converged service changes over time. In this paper, we argue that a method for profile-based dynamic service binding is required to support evolution of converged services. In order to identify requirements for the proposed method, a business scenario with a smart athletic equipment is given. We then present the concept and architecture of the method for profile-based dynamic service binding to meet the identified requirements. We also demonstrate a prototype implementation for evaluating the proposed method.

Reference modeling for Collaborative Networked Organizations(CNOs) has just started, and Enterprise Architecture Modeling Languages(EAMLs) for CNOs are very few. Lack of reference models makes it difficult for people to communicate with each other and lack of EAMLs also makes it difficult to implement information systems for CNOs. We propose an EAML for CNO called CAML. It supports (1) multi-level modeling based on Model- Driven Architecture of OMG's for expressive power and efficiency of implementations, and (2) multi-focus modeling based on Zachman Framework for completeness of modeling The effectiveness of the CAML is investigated through modeling of a supply chain and execution of change impact analysis.

최근, 인터넷이라는 개방형 네트워크가 보편화 되면서 인터넷을 매게로 한 전자적인 거래의 형태가 기업 대 소비자(B2C) 거래에서부터 기업 대 기업(B2B) 거래 그리고 기업 대 정부(B2G) 거래까지 다양하게 발전하고 있다. 본 논문에서는 WfMC에서 제시하는 표준을 준수하면서 동시에 워크플로우 시스템의 사용자인 프로세스 설계자 그리고 워크플로우 프로세스 참여자 모두에게 쉬운 인터페이스를 제공할 수 있는 워크플로우 시스템의 아키텍처 및 모델을 제시한다. 본 모델은 P2P기반의 현실적인 대안을 위해서 설계되었으며, 기존 연구에서 가볍게 취급되어 왔던 워크플로우 시스템 사용자를 위한 인터페이스를 고려하여 설계되었다.

Ontologies are expected in various areas as promising tools to improve communication among people and to achieve interoperability among systems. For communications between different business domains, building an ontology through integrating existing ontologies is more efficient way than building the ontology without them. However, integration of ontologies is very struggling work since languages, domains, and structures of ontologies are different from each other. In this paper, we suggest an Ontology Architecture which solves this problem by providing a systematic framework to classify ontologies from three kinds of viewpoints : language, domain range, constructs. The Ontology Architecture consists of 3 axes according to the 3 viewpoints : Ontology Meta Layer axis, Semantic Domain Layer axis, and Ontology Constructs Layer axis. Because 3 axes in Ontology Architecture are designed to improve the syntactic and semantic interoperability among ontologies, the integration of ontologies can be readily achieved.

With the advance of information technology, it is possible to build the interactive communication channel among relationship participants with low cost, and this channel makes ties between consumers and company by enabling information sharing and exchange. In order to maintain customer relationship, it is necessary to support customer information that includes of-the-customer, for-the-customer, and by-the-customer information. From the three types of customer information, the proper information for the relationship management like the level and type of commitment can be extracted. Customer Information System (CIS), which includes database, communication channel, application program, should be designed to facilitate the customer relationship management. Since lots of investments to information system are required, it is not easy to implement. This paper develops a framework of dynamic customer relationship management and suggests an effective information technology strategy to support that.
