A Commutative Model Composition Operator to Support Software Adaptation

The adaptive software paradigm supports the definition of software systems that are continuously adapted at run-time. An adaptation activates multiple features in the system, according to the current execution context (e.g., CPU consumption, available bandwidth). However, the underlying approaches used to implement adaptation are ordered, e.g. the order in which a set of features are turned on or off matters. Assuming feature definition as …
