Architectural Sustainability refers to the ability of an architecture to achieve its goals while sustaining its value on dimensions related to environmental, social, economic, individual and/or technical during its operation and evolution. While the process of architectural design implies a fit between the requirements, system conditions and constraints; incomplete information and uncertainty may...
When confronted with their internal and environmental dynamics, various software systems increasingly require self-adaptation capabilities. The vision above requires the self-adaptation approach to tackle these challenges and some software systems have their own specific implementations. However, in this paper a general supporting framework is proposed for software systems to self-adapt with running...
Software architecture is critical to the success of large software systems. It has long been recognized that architectural design has profound impact on the achievement of system requirements. Two typical methods have been proposed to help users to make architectural decisions based on requirements. One method uses risk-based reasoning to help choosing good architectural design that can meet both...
An effective software design should ensure that all the quality requirements of a system of interest are supported. As the architecture of a software system can be seen as a set of architectural design decisions (ADDs), the identification of design issues and the choice of design alternatives heavily impact the quality of software systems. This is especially challenging in service orientation for...
As ubiquitous virtual reality (U-VR) systems become more and more popular and several systems coexist all together, sharing events between them in order to improve the user experience and increase their scope and functionality will be mandatory. Since U-VR systems have a dynamic and decoupled nature, and they have their own event model, we propose in this paper a semantic publish/subscribe infrastructure...
We address the specification and the formal analysis of systems involving multiple facets. This leads to heterogeneous specifications that cover the different facets of these systems. A method, multifacet specification and analysis, is proposed to master the heterogeneity of systems by considering an abstract reference model that is referred to as a semantic reference for the specific models which...
An important issue to the adoption of any enterprise architectural approach is the availability of tools to support the development, storage, presentation, analysis, improvement and evolution of enterprise architecture representations. As with enterprise architecture methodologies, enterprise architecture tools to support the architectural development process are still emerging. Most important software...
