Towards a Continuous Requirements Engineering Framework for Self-Adaptive Systems

Requirements engineering (RE) for self-adaptive systems (SAS) is an emerging research area. The key features of such systems are to be aware of the changes in both their operating and external environments, while simultaneously remaining aware of their users’ goals and preferences. This is accomplished by evaluating such changes and adapting to a suitable alternative that can satisfy those changes in the context of the user goals. Most current RE languages do not consider this ‘reflective’ and online component of requirements models. In this paper, we propose a new framework for building SAS that is goal- and user-oriented. We sketch a framework to enable continuous adaptive requirements engineering (CARE) for SAS that leverage requirements-aware systems and exploits the Techne modeling language and reasoning system. We illustrate our framework by showing how it can handle an adaptive scenario in the travel domain.
