The widespread construction of software systems from pre-existing, independently developed software components will only occur when application builders can adapt software components to suit their needs. We propose that software components provide two interfaces { one for behavior and one for adapting that behavior as needed. The ADAPT framework presented in this paper supports both component d...

Developing agent-oriented systems is still a difficult task. However, a component-based approach can help by supporting both modular modification of existing systems and construction of new systems from existing parts. In this paper we develop a foundation (conceptual model) for a component-based agent development framework by extending the concepts of the SMART framework. We apply our definiti...

Our paper deals with the update of componentbased software architectures, i.e. all the modifications which can be performed on the architecture’s elements to satisfy various requirements. Current researches on the component-based software engineering propose various mechanisms to adapt, evolve, customize, or reconfigure such architectures. We are convince that these mechanisms, even powerful, s...

Component-Based Software Engineering (CBSE) allows developers to build systems using existing components. Developers need to find the best set of components that implements most of required features. Retrieving components manually can be very complicated and time expensive. Tools that partially automate this task help developers to build better systems with less effort. This paper proposes a me...

Features and components are two different structuring mechanisms for software systems. Both are very useful, but lead to different structures for the same system. Usually, features are spread over more than one component. In this paper, we aim at reconciling the two structuring mechanisms. We show how component orientation can support adding new features to a base system. We present a method fo...

Hardware Engineers have shown that building systems from components has brought enormous benefits. Using components permits hardware engineers to consider systems at an abstract level, making it possible for them to build and reason about systems that would otherwise be too large and complex to understand. It also enables them to make effective reuse of existing designs. It seems reasonable to ...

This paper presents a method for evaluating and selecting off-the-self software components to be reused in software development. The paper describes the main motivation and principles of the method and provides a provides a detailed description of it. The method has been tried out in two case studies and initial results of these studies are reported. * This work has been supported by the Hughes...

The construction of software systems from pre-existing, independently developed software components will only occur when application builders can adapt software components to suit their needs. Our ADAPT framework [Hein97] supports both component designers in creating components that can easily be adapted, and application builders in adapting software components. We propose that software compone...

This paper discusses dependencies analysis significance when updating component-based system dynamically. It presents a service-based matrix model and nested graph as approaches to capture components' dependencies; it discusses using dependencies analysis for safe dynamic updating in component-based software systems; we advocate using service-based dependencies rather than component-based which...
