Software product line (SPL) engineering is a reuse paradigm that helps organizations increase productivity and improve product quality by developing product from reusable core assets. In SPL, product configuration is the process of selecting the desired features and feature attributes for a given product from a feature model. In order to develop a successful product, feature and feature attribute selection that can achieve the product goal is important. There can be thousands of features and feature attributes resulting in myriads of configurations and finding the best configuration efficiently is a hard task. This paper proposes a systematic process for feature-based product configuration. To support development of a product that satisfys all product goals(business goals and quality goals), a model showing how feature and feature attribute combinations are related to product goals is included and a method for deriving an optimal product configuration using the model is proposed.

Many companies have tried to adopt Software Product Line Engineering for improving the quality and productivity of information systems and software product. There are several models defined in software product line methodology and each model has different abstraction level. Therefor it is important to maintain the traceability and consistency between models. In this paper, consistency checking rules are suggested by traceability matrix of work products.

프로덕트 라인은 다양하게 빠르게 변화하는 시장의 요구사항과 특정 도메인에 속하는 응용들 간의 재사용 가능한 아키텍처 및 컴포넌트의 구성으로부터 연관된 시스템 구축 시 생산성과 품질의 향상을 제공함으로써 현재 많은 관심의 초점이 되고 있다. 이들 프로덕트 라인에서는 프로덕트들 사이의 공통성과 변화성에 초점을 두고 이들 분류 방법으로 휘처 모델링이라는 개념을 주로 사용하여 분석하고 있다. 또한 재사용 가능한 아키텍처는 많은 변화 계획들과 메커니즘을 포함하고 있다. 그러나 지금까지 이러한 변화들이 일어나는 상황을 이해하는 것과 특별한 상황에서도 가능하게 하는 옵션들을 기록하는 것은 명확히 이루어지지 못하였다. 따라서, 명확한 변화성의 표현과 아키텍처에서 변경되는 적절한 위치를 식별하는 것이 중요하다. 그러므로, 본 논문에서는 휘처 모델을 기반으로 한 아키텍처 상의 컴로넌트 변화성과 컴포넌트 간의 관련성에서의 변화성 표현방법을 기술하고. 제시한 이론을 기반으로 웹 학습 시스템을 개발하고자 한다.

프로덕트 라인은 다양하고 빠르게 변화하는 시장의 요구사항과 특정 도메인 영역에 속하는 애플리케이션 간의 재사용 가능한 아키텍처 및 컴포넌트의 구성으로부터 연관된 시스템 구축시 생사성과 품질의 향상을 제공함으로써 현재 많은 관심의 초점이 되고 있다. 또한, 이들 프로덕트 라인에서는 프로덕트들 사이의 공통성과 변화성에 초점을 두고 이들 분류 방법으로 휘처 모델링이라는 개념을 주로 사용하여 분석하고 있다. 또한 재사용 가능한 아키텍처는 많은 변화 계획들과 메카니즘을 포함하고 있다. 하지만, 아키텍처를 설계하기 위한 아키텍처에서의 변화성 관리에 대한 명확한 방법이 미흡하다. 따라서 본 논문에서는 재사용 가능한 아키텍처를 설계하기 위해 변화성의 명확한 표현과 아키덱처에서의 적절한 위치를 식별하기 위해, 다양한 변화성 타입을 정의하고, 휘처 모델을 기반으로한 아키텍처의 변화성과 아키덱처의 컴포넌트 관련성에서의 변화성 표현 방법을 기술하고 사례 연구로 웹기반교육 시스템 개발에 적용하고자 한다.

As software systems become more complex and larger, software systems require a way to reuse software components or modules to provide new functionality. This paper designed a development method of web system combining SOA(Service Oriented Architecture) with MPSL(Multi-Software Product Line). According to provides SOA and MPSL, this paper suggested to service providers and service users to provide and reuse variable services. From the viewpoint of service provider, the suggested method identifies and implements reusable variable services as features by syntax-based, functional-based, and behavior-based methods applying feature identification guidelines and manages them as reuse assets. From the user's point of view, it is possible to develop a web system by constructing a service by workflow model as a method of structure and reconfigure services. As a result of measuring the reuse of the web system constructed in this paper by the function point, the cost reduction effect was verified by applying it to the similar project with the increase of reuse.

Application developers need effective reuseable methodology to meet rapidly changes and variety of users requirements. Product Line and CBD(Component Based Development) offer the great benefits on quality and productivity for developing the software that is mainly associate with reusable architectures and components in a specific domain and rapidly changing environments. Product line can dynamically focus on the commonality and variety feature model among the products. The product line uses the feature modeling for discovering, analyzing, and mediating interactions between products. Reusable architectures include many variety plans and mechanisms. In case of those architecture are use in product version for a long time, It is very important in architecture product line context for product line design phase. Application developer need to identify the proper location of architecture changing for variety expression. It is lack of specific variety managements to design the product line architecture until nowdays. In this paper, we define various variety types to identify the proper location of architecture changing for variety expression and to design the reusable architecture. We also propose architecture variety on feature model and describe variety expression on component relations. We implemented the web learning system based on the methodology. We finally describe how these methodology may assist in increasing the efficiency, reusability, productivity and quality to develop an application. In the future, we are going to apply the methodology into various domain and suggest international and domestic's standardization.

In order to improve working speed, add more functions and provide better user interface of ASADAL, the AWT based Java application to support FORM Software Product Line Development Methodology; we had to reengineer this application to be Eclipse based plug-in application. In order to improve working speed, add more functions and provide better user interface of ASADAL, the AWT based Java application to support FORM Software Product Line Development Methodology; we had to reengineer this application to be Eclipse based plug-in application. And then, this paper introduces the plug-in developed by applying guidelines presented in the reengineering cases of ASADAL's feature model editor and behavior model editor.
