Abstract

Developers of systems of systems (SoSs) face challenges such as heterogeneous, inconsistent, and changing elements; continuous evolution and deployment; decentralized control; and inherently conflicting and often unknowable requirements. In response to these challenges, researchers are developing the ReMinds tool. Engineers can use it to instrument systems in an SoS to extract events and data at runtime and to define requirements as constraints to check expected behavior and properties. ReMinds can also visualize and explain requirements violations to facilitate diagnosis.
