The System Dynamic Adaptability Concern
Abstract
In this chapter, the essence of the dynamic adaptation capability is examined from the perspective of requirements modeling. Dynamic adaptation is shown as a metalevel capability that is about the variability of the concrete application. Variability and the response to it are modeled as different conformance relationships among the application models: i.e., goal, environment, and basic system. Three kinds of conformance are differentiated to capture dynamic adaptation: goal-oriented adaptation, stimulus/response adaptation, and fine-grain adaptation. Feature models are used as the unique representation of these models, and then a new rule-based representation is used to represent the conformance ...
