다양한 표준에 정의된 내용을 가지고, 각 도메인에서 사용할 수 있는 프로세스를 구축하는 일은 어렵다. 왜냐하면 표준의 어떤 부분을 어떻게 tailoring 하여야 하는지에 대한 지침이 부족하기 때문이다. 사실 표준은 표준대로 존재할 뿐, 실제 프로세스 정의에는 사용되지 못하고 있다. 따라서 본 논문에서는 컴포넌트 기반 개발 개념을 이용하여 다양한 도메인에 맞게 프로세스를 tailoring하는 방법을 제안한다. 우선 테스트 프로세스를 언급하는 다양한 표준들로부터 테스트 프로세스 컴포넌트를 정의하고, 이들을 특정 도메인에 맞게 tailoring 하기 위한 맞춤(customization), 조립(composition) 방안을 제안한다. 본 논문에서 제안한 방법은 테스트 프로세스 컴포넌트의 인터페이스만을 고려하고 주어진 플로그인들을 이용하여, 맞춤.조립만을 수행함으로써, 체계적으로 tailoring된 테스트 프로세스를 구축할 수 있도록 한다.

Travel demand forecasting is the important process of transportation policy and planning, especially trip assignment is also important because it finds deficiency of network GIS can be applied to transportation due to its various merits. Recently Program development environment is changed to component-based and transportation-component is necessary. This study evolves in implementing trip assignment model with GIS and tries to apply the system to the Cheongju City.

기존의 보안 API는 각 사용자 요구사항 및 추진산업체 또는 표준단체, 개발환경 및 제공 서비스, 함수의 명칭, 자료구조 등이 독립적인 구조를 가지고 있어 각 보안 API에 대한 총괄적 표준화에 어려움이 있었다. 또한, 오늘날 하루가 다르게 급변하는 요구사항에 대하여 적시성을 제공하기에 부적합하였다. 이에 따라 소프트웨어의 품질을 보증하고 적시성을 제공할 수 있는 컴포넌트 기술이 제안되었다. 본 논문에서는 다양한 소프트웨어 비즈니스 모델 개발에 다목적으로 활용 가능한 새로운 패러다임의 컴포넌트 설계기법을 표준적 암호서비스 기술 개발에 도입하여 암호서비스에 패한 상호운용성의 확보와 이기종 시스템간의 상호호환성 및 필요한 모듈의 추가 및 변경의 용이성 등을 제공하기 위하여 암호컴포넌트 서비스 지원을 위한 HSSM을 설계하였다.

컴포넌트는 일반적으로 객체 모델링을 기반으로 설계되고 개발되기 때문에 상호작용과 협력의 표현, 상속으로 인한 재사용 문제 등을 해결하는 데는 한계가 있으며 복잡한 구조를 가진 대규모 시스템에서 컴포넌트를 추출하기에는 용이하지 않다. 따라서 객체 모델링을 보완하기 위하여 객체 중심이 아닌 객체의 역할을 중심으로 하는 역할 모델링 기법이 제안되었다. 본 연구는 UML 기반에서 다양한 관점의 역할 모델을 표현하여 컴포넌트를 추출하는데 활용할 수 있도록 한다.

Modular product design has contributed to flexible product modification and development, production lead time reduction, and increasing product diversity. Modular product design aims to develop a product architecture that is composed of detachable modules. These modules are constructed by maximizing the similarity of components based on physical and functional interaction analysis among components. Accordingly, a systematic procedure for clustering the components, which is a main activity in modular product design, is proposed in this paper. The first phase in this procedure is to build a component-to-component correlation matrix by analyzing physical and functional interaction relations among the components. In the second phase, network flow modeling is applied to find clusters of components, maximizing their correlations. In the last phase, a network flow model formulated with linear programming is solved to find the clusters and to make them modular. Finally, the proposed procedure in this research and its application are illustrated with an example of modularization for a vacuum cleaner.

Modeling and simulation techniques construct experimental environment considering battlefields and are able to analyze performance of components of weapon system that closely resemble reality. However, developed model has low scalability and not cared reusability because it has been used only in a limited range of domain. In this paper, we develop a verification tool to verify reusability of developed component for dynamic reconfiguration and to judge scalability of it and a management tool to control data of it effectively. In addition, dynamic reconfiguration architecture of guided weapon systems designed in the previous study has been applied to SAM(Surface to Air Missile) System Simulator, and we study effectiveness of the developed component. Thus the user can configure various guided weapon systems through simulation application of dynamic reconfiguration architecture of component.

As new and diverse information technologies are being introduced and software complexity is increased, software development cost and efforts are also sharply increased. Component-Based Development (CBD) technology is appealing as a new way to reduce the cost and effort by increasing reusability and maintainability. Component in CBD has variability infernally which enables customization of the component within the specific domain. A component user can easily set up internally variability parts though Required interface which is provided by the component. Enterprise JavaBeans (EJB) is utilized as a commercial standard to implement Java-based components. However, EJB constructs are limited in directly implementing Required interfaces of coarse-grained components［8］. In this paper, we define Required interface and propose interface-storage technique, class-storage technique, interface-generation technique, and Plug -in technique for implementing required interface of component. Interface-storage technique stores variable value in Required interface and class-storage technique take the Bean containg variability as Required interface without modification of component model. Interface-generation technique generates new Bean which takes the role of Required interface for component variability and Plug-in technique sets up component variability that component user plugged-in variable part externally The proposed four techniques conform to the semantics of CBD component interface and enable the implementation of high quality components.

Recently software industry in GIS(geographic information system) becomes an interesting issue by performing a large scale of national GIS application development as well as even small unit of FMS(facility management system). Also, there exist many cases to combine GIS with various business domains such as MIS(marketing information system), CNS(car navigation system) and ITS(intelligent transportation system). In this situation, in order to develop an efficient and useful GIS application for a short term, there must be a deep consideration of not only developing GIS component but also managing GIS component. In fact, even though there exist many certain components having high reusability, excellent interoperability and good quality, their reusability may be reduced because of their difficulty to access in a certain repository. Therefore, it is important to classify components having common characteristic based on their particular rule with reflecting their functionality and non-functionality before cataloging them. Here, there are two non-functional classification categories discussed such as GIS content-dependent metadata and GIS content-independent metadata. This cataloged components will help application developers to select easily their desired components. Moreover, new components may be easily producted by modifying and combining previous components. Finally, the original goal of all this effort can be defined through obtaining high reusability and interoperability of GIS component.

As for the software development, it is complicated, and size of software is growing larger. And contraction of a software development period is required acutely because it is short a period of software life cycle. Also, it becomes harder development and a maintenance because it is short a life cycle of developed software. According to this an effort is increased in order to reduce a development cost and time as using a component to have been implemented previously in development of software. A current component technology is developing into a very fast speed and is bringing a large change into development of a Web base system in addition to existing software development method. In this paper, we were handling a related technology for Web system development of a CBD base systematically and derived an issue to apply it to development of a Web system and presented an efficient practical use method of a component technology. First of all we looked into a component technology and a CBD methodology systematically and described a component technology in Web. Also, we proposed a method to increase development and efficiency of practical use of a Web system based on a component. The this study result can decrease a development cost of a Web system and a load of maintenance management through the re-use of a code.

Recently, large-scale enterprise information systems are commonly based on the multi-tiered middleware or frameworks to support such requirements as functional reuse, heterogeneous system resources, and multiple platforms. However, these multi-tiered or distributed multi-platform architecture incurs the interoperability issue of the components and metadata among the middleware. This paper introduces the Simple Object Application Framework (SOAF) which supports heterogeneous resources and platform-independent component-based development, with the abstract programming style of the object-oriented frameworks and the XML-SOAP based component persistence mechanism.
