Software-intensive systems in application domains like autonomous agriculture, avionics and healthcare need to be more and more adaptive. Dynamic integration of components and a subsequent reconfiguration at runtime results in changed functional and non-functional properties of the system. Taking into consideration that these systems often operate in safety-critical environment, reconfiguration apropos of safety becomes a crucial concern. To this end, in my research, I have introduced a conceptual framework that aids in safe reconfiguration of an open system-of-system, by the means of systematic monitoring and evaluation of the system and its components at runtime.

The concept behind the framework is to dynamically ensure safety by rigorous monitoring of operational status of system, its components and the environmental conditions during its execution, thereby managing system reconfiguration by evaluating system status in accordance with safety property. Owing to reconfiguration management at runtime, the framework is henceforth referred to as RM@RT. The metamodel consists of an Open Adaptive System (OAS) as top element. We consider that the systems composing an OAS are also capable to reconfigure, and thus refer to them as Adaptive Components (ADC). This makes an OAS a composition of multiple adaptive components.
