본 논문에서는 재사용가능한 소프트웨어 부품의 분류 과정을 자동화하여, 소프트 웨어 부품 라이브러리에 구조적으로 저장하는 방안을 제안한다. 효율적이고 자동화 된 소프트웨어 부품의 분류를 위하여 자연어로 기술된 소프트웨어 부품 설명서로부터 의미 정보와 문장 구성 정보 등의 특징을 획득하여 소프트웨어 부품의 특성을 표현하 는 패싯을 결정하고각각의 패싯에 해당하는 항목들을 자동으로 추출하여 소프트웨어 부품 식별자를 구성하였다. 그리고 분류된 소프트웨어 부품들 사이의 의미 유사도를 측정하여 비슷한 특성을 갖는 소프트웨어 부품들을 인접한 장소에 저장시켜 구조화된 소프트웨어 부품 라이브러리를 구축하였다. 제안한 방법은 소프트웨어 부품의 분류 과정이 간단하고, 유사한 소프트웨어 부품을 쉽게 식별할 수 있었으며, 또한 소프트 웨어 부품을 라이브러리에 구조적으로 저장할 수 있다.

Component-based software reuse has been generally regarded as a promising approach to improving software productivity and quality within software development. However, progress in component-based software reuse has been slower than expected. Much of the software reuse literature points to the lack of software components that can maximize users' benefits as the most important source of the slow progress. Considering that the underlying processes behind component-based software reuse are strikingly similar to commercial software marketing, this paper attempts to identify the aspects of software components that consumers value and to establish relationships between the identified aspects and consumer behavior in the software component market. More specifically, this paper focuses on the perceived subjective features of software components. This study was conducted in a web-based artificial market environment called "SofTrade."

Reusing software components without proper analysis is very risky because software components can be used differently from the way that they were developed. This paper describes a new testing approach for reusing software components. With this new approach, it is possible to automatically decide if software components can be reused without retesting. In addition, when retesting is required for reusing software, test cases are generated more efficiently using the previous testing history.

This paper proposes a framework for product development including hardware and software components. The framework provides separation of the hardware dependent software, an integrated product development process, and integration of software components with product configurations and product structures. In order to separates the hardware dependent software, the framework considers product configuration modules and engineering changes of associated hardware and software components. The proposed product development process integrates development of the hardware dependent software into the existing product development process. In order to integrates the hardware dependent software with product configurations and product structures, the framework represents software components by existing product data models in Product Data Management (PDM). The framework is applied to development of a robot system including hardware and software components in order to show its effectiveness.

This paper explores how to characterise security properties of software components, and how to reason about their suitability for a trustworthy compositional contract. Our framework provides an explicit opportunity for software composers as well as software components to test a priori security properties of software components in a system composition. The proposed framework uses logic programming as a tool to represent security properties of atomic components and reason about their compositional matching with other components.

CBSD(Component-Based Software Development)는 이미 존재하는 소프트웨어 컴포턴트를 조립함으로써 시스템을 개발하는 방법이다. 컴포턴트를 이용하여 시스템을 개발하는것을 개발시간과 비용을 줄이고, 생산성을 향상시키는 등 여러 가지 장점을 가진다. 그러나 여러 벤더에 의해 개발된 컴포넌트를 조립하는 것은 쉬운 일이 아니다. 이를 위해 컴포넌트가 어떤 문맥에서 사용되는지 이해하는것이 필요하며, 이 문맥은 아키텍쳐에 의해 결정된다. 따라서 컴포넌트 기반의 어플리케이션 개발은 아키텍쳐를 기반으로 하였을 때 가능하다. 또한 컴포넌트 기반 어플리케이션 개발을 위해서는 도메인 개념이 필수적이다 컴포넌트의 재상용을 높이기 위해서 관련된 시스템의 집합인 도메인에서 컴포넌트를 개발해야 한다. 본 논문에서는 컴포넌트 기반 어플리케이션 개발을 지원하는 도메인 아키텍쳐 개발방법을 제안한다. 도메인 아키텍쳐는 도메인 분석 및 설계과정에서 생성되는 것으로 컴포넌트와 그들간의 관계를 표현한다. 도메인 아키덱쳐를 이용하여 컴포넌트를 개발함으로써 재사용성이 높은 컴포넌트를 효율적으로 개발할수 있을 뿐만 아니라, 어플리케이션 개발 시 도메인에서 제공하는 정보를 이용하여 쉽게 어플리케이션을 개발할수 있다.

It is difficult to design system software to meet a better separation of concerns, which can provide a number of benefits such as adaptability, extensibility, and modularity in the design and implementation. During design, some aspectual properties, such as synchronization, scheduling, performance and fault tolerance, crosscut the basic functionalities of the system software. By separating functional components from the different aspectual components of the system software in the design, we can provide a better generic design model of system software. Aspect-Oriented Programming is a methodology that aims at separating components and aspects from the early stages of the software life cycle, and using techniques to combining them together at the implementation phase. In this paper we discuss an aspect-oriented framework that can simplify system software design and implementation by expressing it at a higher level of abstraction. Our work concentrates on how to achieve a higher separation of aspectual components, functional components, and layers from each other. Our goal is to achieve a better design model for implementing system software in terms of modularity, reusability and adaptability.

AUTOSAR is a partnership of automotive manufacturers and suppliers working together to develop and establish a de-facto open industry standard for automotive software architectures. In the AUTOSAR architecture, the runtime environment is at in the heart of the AUTOSAR architecture to provides the infrastructure services that enable communication between software components and between software components and basic software components. The RTE generator is an automated generation tool for AUTOSAR specification based RTE according to the ECU configuration. It generates communication API function for the software components and the basic software components like OS and COM of the application. The availability and the accuracy of the RTE generator are important for the automobile software which is based on AUTOSAR architecture, this paper proposes an architectural design of the RTE generator for auto-generation of the AUTOSAR based RTE.

To enhance the productivity of software development and accelerate time to market, software developers have recently paid more attention to a component-based development (CBD) approach due to the benefits of component reuse. Among CBD processes, the identification of reusable components is a key but difficult process. Currently, component identification depends mainly on the intuition and experience of domain experts. In addition, there are few systematic methods or tools for component identification that enable domain experts to identify reusable components. This paper presents a systematic method and its tool called a component identifier that identifies software components by using object-oriented domain information, namely, use case models, domain object models, and sequence diagrams. To illustrate our method, we use the component identifier to identify candidates of reusable components from the object-oriented domain models of a banking system. The component identifier enables domain experts to easily identify reusable components by assisting and automating identification processes in an earlier development phase.

The companies are trying to apply to software development approach by utilizing open-source components. The open-source components are new alternatives to solve limits of the previous software developments such as quality of software, time and cost of development. Accordingly, various analysis of open-source components were performed. However, the researches about the detailed procedures and methods to utilize open-source components in practical industry are immature. In this paper, we propose the procedures and cases for identifying, validating, selecting of suitable open-source components and for applying to change and modification. Proposed procedures and cases will be a great contribution to spread of utilizing the open-source.
