요구사항은 아키텍처를 생성할 때 매우 중요한 요소로써 기능 요구사항과 품질 요구사항으로 구분된다. 기능 요구사항은 하위시스템 또는 컴포넌트 생성에 영향을 미치고 품질 요구사항은 아키텍처의 구조를 결정하는데 영향을 준다. 이와 같이 요구 사항은 아키텍처 설계에 중요한 영향을 끼치기 때문에 아키텍처 설계를 위해서는 요구사항에 대한 명확한 이해가 필요하다. 본 논문에서는 요구사항에 대한 명확한 이해를 돕기 위해 요구사항을 정량화하는 방법을 제안한다. 기능 요구사항은 기능적인 우선순위 계산을 통해 컴포넌트를 정량화하고 품질 요구사항은 정량화된 컴포넌트와 품질 속성의 연관성 계산을 통해 정량화한다. 제안된 방법은 DRAMA (Domain Requirements Analysis for Modeling Architectures) 도구를 통해 구현되었으며, 요구사항의 정량화 방법을 실 예제에 적용해본 결과를 소개한다.

The intelligent railway operation information architecture is to provide the railway passengers with the intermodal transportation information service. The purpose of the information architecture is to suggest the information service architecture of the intermodal transportation structurally. First, the architect procedure is to analysis the user requirements and according to these requirements, is to make the description of service requirements. Then secondly, it decides the service items and based of these items, it is to construction of service architecture. Finally, service package provide an accessible, deployment oriented perspective to intelligent railway operation information architecture

The work environment of locomotive cabs has long been an important issue in the design of railload systems since it is quite critical in terms of system's operational safety. It is getting more attention as the running speed of the trains goes up these days. To this end, this paper describes how to systematically construct a DB for the requirements set in the course of the improvement process for the aforementioned cab work environment. As a solution approach, we have adopted the requirement architecture concept to cover the whole activities required to do such as in requirements generation, DB construction, change management, and traceability management. Specifically, based on the requirement architecture framework a requirement process to collect requirements for improvement is discussed, and the guide lines are suggested for verification and validation of the developed requirements. In addition, a base schema and requirements templates are developed, which will be used in generating requirements and constructing a DB. Finally, it is demonstrated how the requirements DB for locomotive cabs can be constructed using a computer-aided tool in an integrated fashion.

Recently the facility requirements and regulations of healthcare facilities for the aged were changed, but the justification of requirements have not been identified. The facility requirements are so important to plan and design the facility. So this paper aims to identify the problems, and to compare & analyse the facility requirements.

Technology-driven development of a new system makes it difficult for users and stakeholders to identify or intervene in the development process, resulting in systems with unnecessary functions and poor quality services. Applying the software architecture design process to the initial design of the navigation system platform of autonomous ships enables the development of a system that reflects the required functions and service quality of the stakeholders. The design, which includes all of the subsystems that make up an autonomous ship platform, is close to an enterprise architecture. Thus, we strived to design a navigation system platform suitable for the design range of the software architecture. This study analyzed the definition of functional requirements, and quality attributes by applying the software architecture design procedure. This study was conducted to identify the characteristics of the navigation system and platform needs, and the stakeholders were identified. To derive the functional requirements and constraints of the platform, a quality attributes workshop was held engaging stakeholders, and the results of the analysis of functional requirements and quality attributes were listed. Based on the results of this study, the architect can establish the evidence and technical solutions that are integral for the architecture development, and will facilitate the creation of quality attribute scenarios.

Most of the multiplayer games available online are based on a client-server architecture because this architecture gives better administration control to the game providers than peer-to-peer architecture. In this architecture, the server is responsible for all the communication between the connected clients. The weakness of this architecture is its bandwidth requirement and scalability. Peer-to-peer architectures have then been proposed to solve these issues. In this paper, we propose a hybrid client-server architecture in which the game state is partially shared by the mobile terminal to achieve consistency among different players. Like a peer-to-peer architecture, this architecture uses client-side capacities to reduce bandwidth requirements for the server and improves consistency in wireless networks. Client events have different timeliness and consistency requirements according to their nature in the game world. These requirements lead to tasks with different priorities on CPU processing. In the proposed architecture, either the server or the client applies consistency mechanism according to the priority level. Simulation experiments show that the bandwidth of the server in this architecture is smaller than that of the client-server architecture. As a result, the server in the proposed architecture can accommodate more clients with enhancing the scalability.

True process collaboration can be accomplished through seamless integration of business processes and enterprise knowledge. Therefore, it is natural that the concept of Business Operating System (BOS), proposed by Delphi Group in 1994, is currently considered as a next evolutionary step for Business Process Management System (BPMS). Literature reports very little work, however, especially, on a comprehensive architecture of the system. This paper proposes an architecture of BOS with the following definition: ' BOS is an intelligent activity supporting system that provides a comprehensive and personalized work environment to each knowledge-intensive worker. ' To propose an architecture of BOS, the paper first identifies and classifies functional requirements for Business Operating System. Then, it proposes a data model and an architecture of the system to satisfy the functional requirements. The proposed architecture focuses on two essential technical requirements. First, the system should provide an effective means to integrate data and processes and to standardize distributed component systems. Secondly, the system should also be intelligent enough to assist workers to perform their knowledge-intensive work. The paper shows how these requirements can be achieved by using Semantic Web and Web Service.

추적성은 소프트웨어 개발자에게 소프트웨어 산출물에 대한 변경을 추적하게 해 준다. 소프트웨어 제품 라인 개발에 있어서의 추적성은 공통성과 가변성을 고려해야 하기 때문에, 개별 제품에서의 추적성보다 복잡하다. 과거 연구에서 제품 라인 개발에서의 제품 피처와 요구사항 간의 추적성 구축을 제시되었다. 그러나 요구사항과 아키텍처 설계 사이의 추적성 구축은 다 대 다 관계와 아키텍처 계층으로 인해 고려해야 할 요소가 더 많다. 본 논문은 이러한 요소들을 고려하여, 제품 라인 개발에서의 요구사항과 아키텍처 사이의 추적성을 모델링하는 체계적인 방법을 제공한다. 또한 사례연구를 통하여 이 방법이 효과적임을 보인다.
