우리의 일상생활에서 차지하고 있는 소프트웨어의 비중은 점점 더 커져가고 있으며, 그만큼 소프트웨어의 오류가 우리에게 미치는 영향도 커지고 있다. 또한, 현대의 소프트웨어는 더 복잡해지고 높은 안정성이 필요하게 되므로 기존 소프트웨어와는 다른 새로운 패러다임의 소프트웨어가 필요하다. 적응형 소프트웨어는 소프트웨어 스스로가 자신의 기능을 추론하고 오류가 발생하면 이에 적절하게 대처할 수 있는 새로운 소프트웨어 패러다임이다. 적응형 소프트웨어를 개발하려면 소프트웨어가 적응해야 하는 상황을 모델링 하는 기술이 필요하다. 본 논문에서는 프로덕트 라인 개발 방법에서 사용하는 휘쳐 모델을 사용해 적응형 소프트웨어의 상황을 모델링 하는 기법을 제안한다.

Business entities with which most service components interact are kind of cross-cutting concerns in a multi-layered distributed application architecture. When business entities are modified, service components related to them should also be modified, even though they implement common functions of the application framework. This paper proposes what we call DTT (Data Type-Tolerant) component model to process the variability of business entities, or externalized data, which feature modern application architectures. The DTT component model expresses the data variability of product lines at the implementation level by means of SCDTs (Self-Contained Data Types) and variation point interfaces. The model improves the efficiency of application engineering through data type converters which support type conversion between SCDTs and business entities of particular applications. The value of this model lies in that data and functions are coupled locally in each component again by allowing service components to deal with SCDTs only instead of externalized business eutities.

The information flow through RFID techniques such as, standardized EPC and EPCglobal network suggests new change in the method of cooperating and sharing information in the supply chain. Common function should be prepared for communication, security techniques, and business processes based on the EPCglobal standard to introduce efficient RFID techniques. And the standard architecture which can deal with the RFID environment flexibly is quite necessary. Therefore, this paper suggests Enterprise Application Framework (EAF) for developing efficient and secure RFID applications. EAF offers essential services to develop RFID enterprise systems : a communication environment which uses various standard communication protocols, a security function based on PKI, and abstract business services for flexible introduction of RFID businesses. It simplifies the RFID business integration, minimizes the development complexity, and thus EAF is expected to reduce the cost of RFID application development. EAF guarantees constructing secure RFID applications due to PKI-based security mechanism.

Nowadays, lots of requirements are changed quickly and variously. So, we need the ability to support the change of business process which is the asset of a company. To support this ability, the core asset that supports analyzing and describing about changes of business process should be exist from generating phase of a business process model. And a business process model that is satisfied the changed requirements should be automatically generated using core assets. In this paper, we present a business process family model (BPFM) which represents the commonalities and the variabilities of a set of business processes, we propose the automated tool using variabilities of BPFM and decision-making information for generation of business process model that is satisfied the changed requirements.

Recently, the business process family model (BPFM), which is new approachfor assuring businessflexibility and enhancing reuse in application development with service oriented architecture (SOA), was proposed. The BPFM is a model which can explicitly represent the variabilities in business process family by using the variability analysis method of software product line. Many business process models (BPM) can be generated automatically through decision and pruning processes from BPFM. At this time, the variabilities tend to have inclusive or exclusive dependencies between them. This affects the decision and pruning processes. So far, little attention has been given to the binding information of variability dependency in the BPFM. In this paper, we propose an approach for analyzing various types of dependency relationships between variabilities and representing the variability and their relationships as a dependency analysis model. Additionally, a method which can trace the variabilities affected by a decision on the dependency analysis model is presented. The case study shows that the proposed approach helps to reduce the number of variability decision and to solve a disagreement of functions in BPM produced by incorrectly deciding the variability.
