Product-Line 개발방법에서 가변성의 표현과 선택은 최종 Product의 형태를 결정하는 중요한 요소이므로 개발 전 단계에서의 일관성 있는 관리가 필요하다. 현재 Product-Line에서 가변성의 표현을 위한 다양한 방법들이 연구되고 있지만 실제적으로 개발 단계간의 가변성의 연관된 변화과정을 서술하고 관리할 수 있는 방법은 부족한 실정이다. 본 논문에서는 소프트웨어 개발단계의 각 계층 간 가변성을 표현하는 방법을 정의하고 이 방법으로 Product-Line의 가변성이 효율적으로 관리될 수 있음을 증명한다. 본 논문에서 제안하는 Variation View를 이용하면 S/W 전체의 가변성의 변화를 한눈에 파악할 수 있고, 가변성 결정에 따른 소프트웨어 변화를 예측할 수 있으며, 향후 evolution 과정에서도 공통 아키텍처를 유연하게 확장할 수 있는 방법을 제공할 수 있다.

Ubiquitous computing spans a very broad range of technologies and needs very complicated user's requirements. There are many scenarios and technologies involved in ubiquitous computing. We need new software development tools and methodology to meet the requirements. A software product line is one of promising new technology for it. A software product line is a set of software intensive systems that share a common, managed set of features satisfying the specific needs of a particular market segment or mission and that are developed from a common set of core assets. Software architecture-based development is the exploration and maturation of the role of software architecture in the product line life cycle. In this thesis, we identify the foundational concepts underlying software product lines and the essential activities to develop the mobile application systems. So, we define, design, and implement the Mobile Application System Architecture(MASA) that includes the development process for applying into mobile business domain and encompass scoping and gathering requirements for the Product line based on Component Based Development(CBD).

Testing approaches for configurable software product lines differs significantly from a single software testing, as it requires consideration of common parts used by all member products of a product line and variable parts shared by some or a single product. Test coverage is a measure of the adequacy of testing performed. Test coverage measurements are important to evaluate the adequacy of testing at the software product line level, as there can be hundreds of member products produced from configurable software product lines. This paper proposes a method for measuring code coverage at the product line level in configurable software product lines. The proposed method tests the member products of a product line after hierarchizing member products based on the inclusion relationship of the selected features, and quantifies SPL(Software Product Line) test coverage by synthesizing the test coverage of each product. As a result of applying the proposed method to 11 configurable software product line cases, we confirmed that the proposed method could quantitatively visualize how thoroughly the SPL testing was performed to help verify the adequacy of the SPL testing. In addition, we could check whether the newly performed testing for a member product covers the newly added code parts of a feature.

This study investigated the differences in the importance of store characteristics depending on on-line clothing store type and consumer age. The questionnaires were given to female residents in the ages between 20-39 in Seoul and Kyung-gi province during October 2006. The results were summarized as follows: 1. By analyzing the differences in importances of on-line store characteristics factors it was found that buying process service factor and product searching system factor were important in on-line general merchandise store. and buying process service factor and product factor(all the factors, such as store credit, product, screen-displayed design, searching and approaching system, customer management service) were important in on-line specialty store. 2. By analyzing the differences in importances of on-line store characteristics depending on the store type, buying process system such as refund policy, shipping, high-speed payment and rapid searching, screen-displayed design system, approaching and searching system were more important in on-line general merchandise store when comparing to specialty store. It also showed that the consumer considered the reputation of the store and its image more important in on-line general merchandise store. 3. By analyzing the differences in of on-line clothing store importance depending on age, in the case of on-line general merchandise store, it showed that people in their thirties regarded buying process service factor more important than twenties, and when it came to the product and searching system, it was vice versa. Twenties had a tendency to consider the aspect of product important and, relatively, thirties regarded searching and approaching system factor important. in the case of specialty store. It was found that women in their twenties had a tendency to consider product factor more important.

Software product line engineering is widely recognized as an effective way for systematic software reuse, and many studies have been conducted to convert existing software development practices and processes into software product line. In order to convert existing software development into product line, a lot of investments are required such as dedicated development units, appropriate process selection and adaptation, and tool support. In particular, small businesses need business cases and specific practices for applying software product line engineering before its full-scale adoption. In this paper, we present a practical case of applying software product line engineering to the development of web system families and a process of systematically building and reusing software assets. To do this, we analyzed a number of web development projects and presented the experiences and various considerations of small software companies adopting software product line.

The increased availability of store brand suppliers now provides retailers with opportunities to create their own lines of vertically differentiated multiple store brands within a product category. As the number of store brands increase, the retailer's shelf space becomes more crowded, which may force the retailer to consider dropping some national brands from its assortment. Despite these trends, the problem of product line design in a vertically differentiated product category has been analyzed mainly from a manufacturer's perspective in the marketing literature and it is not known to what extent the findings of the existing product line design literature provide applicable strategic guidelines for the new problem faced by retailers. In this study, we address this deficiency in the literature and conduct an in-depth study of the retailer's strategic design of a line of store brands and its assortment decision within the context of retail category management. We analyze the retailer's decision about not only how to design a line of store brands but also which national brand to drop from its assortment. The results of our analysis are as follows. First, if the retailer has to drop one of national brands from its assortment, it is the best for the retailer to drop the low-quality national brand rather than the high-quality national brand. Second, the retailer has to position the high-quality store brand relatively close to the high-quality national brand, remained on its shelf, in terms of quality so as to maximize the size of retail margin from the national brand. On the other hand, the retailer should set the quality of the low-quality store brand at a lower level than that of the low-quality national brand to increase the total category demand by attracting more price sensitive consumers. By doing so, the retailer can also minimize cannibalization between two store brands. Lastly, our analysis shows that the introduction of a line of store brands improves consumer welfare by increasing real values of all products on the shelf.

In this paper, we have studied how to reuse common data link software by applying software product line engineering. Existing common data link software performed different stages of design, implementation, and testing without sharing the accumulated knowledge of different developers. In this situation, developers agreed that sharing the assets of each project and reusing the previously developed software would save human and time costs. Even with the initial difficulties, the common Data Link is a continually proposed project in the defense industry, so we decided to build a product line. The common data link software can be divided into two domains. Among them, the initial feature model for the GUI software was constructed, and the following procedure was studied. Through this, we propose a plan to build a product line for core assets and reuse them in newly developed projects.

Product-Line 기반의 소프트웨어 개발은 특정 도메인의 소프트웨어 제품군 내의 공통성과 가변성 분석을 통한 공통 아키텍처의 추출과 재사용으로 개발의 생산성과 효율성을 향상시킨다. 일반적인 Product-Line 기반 방법론에 따르면, 재사용되는 핵심자산은 아키텍처, 컴포넌트, 등의 소프트웨어 내부 비즈니스 로직에 한정되어 있으며, 실제로 소프트웨어 개발에 있어 많은 비용이 지출되는 UI(User Interface), 데이터베이스 등의 설계 및 개발에 대한 내용은 언급되어 있지 않은 실정이다. 본 논문에서는 소프트웨어 개발에 필요한 UI 모듈을 핵심자산의 형태로 Product-Line 에서 사용할 수 있도록 하는 방법을 제안한다. UI 모듈을 설계하여 명세하는 방법과 설계된 UI를 디자인 템플릿과 연결하여 내부 로직과 연계하는 방법에 대해 설명한다. 이 방법을 이용하면 Product-Line을 위한 핵심자산 구성시 UI 모듈을 포함할 수 있어 생산성과 효율성을 향상시킬 수 있을 것으로 생각된다.
