A collaboration supporting system, which enables multi-user collaboration and communication in Internet environment, is being a new indispensable tool to compete and collaborate with business peers. A collaboration supporting system in distributed environment requires scalable and open system architecture to rapidly deploy a new technology and trends. In this paper, we propose such a collaboration supporting system where communication API is using XML(Extended Markup Language)-based SOAP(Simple Object Access Protocol)protocols, which Is independent on programming language and platform. In our system, server components are developed with EJB(Enterprise Java Beans). System analysis, design, and development are based on UML(Unified Modeling Language).

Use case modeling on UML (Unified Modeling Language) is getting widely used in OOAD and CBD and it is considered a useful technique in dealing with the complexity of the requirements analysis. However, some of the problems with use case modeling are that it is not structured, difficult to handle non-functional requirements, and to analyze impacts among use cases. To alleviate these problems, we propose a scenario-based goal-oriented approach for use case modeling. The proposed approach is to apply a goal-oriented analysis method to use case modeling. Since goal-oriented analysis method is not systematic and many heuristics are involved, we have adopted scenarios as the basis for goal extraction. The proposed method is applied to CBIS (City Bus Information Subsystem) in ITS (Intelligent Transportation System) domain. The proposed approach helps software engineers to analyze the impact among use cases and represent non-functional requirements.

본 논문은 다양한 종류의 분산 인공지능 문제들을 에이전트라는 추상적 단위와 에이전트간의 상호작용을 토대로 해결하는 다중 에이전트 시스템을 개발하는 체계적 접근방법으로서 개발 방법론의 핵심인 아키텍쳐의 개발방법을 제안한다. 목표를 기반으로 문제영역을 이해하고, 여기에서 추출된 에이전트들을 이용하여 시스템을 개발함에 있어 지침이 되는 아키텍쳐 개발공정을 다중 에이전트 시스템의 특성인 조정과 자율성을 고려하여 제안한다. 각 관점마다 적용될 수 있는 아키텍쳐 스타일과 패턴들을 정의하고, 제안한 아키텍쳐를 UML(Unified Modeling Language)을 이용하여 표현하며, 아키텍쳐를 설명하는 ADL(Architecture Description Language)을 이용하여 정형화시킨다. 또한, 이를 지능형 교통시스템의 출발전 교통정보 안내 서브시스템에 적용, 구현함으로써, 제안하는 아키텍쳐를 검증해 보고, 이를 기반으로 소프트웨어를 개발하는 기초를 마련한다.
