Eliciting context-oriented NFR constraints and conflicts in robotic systems

Non-functional requirement (NFR) conflicts pose a serious threat to any system, especially robotic systems, where identifying conflicts prior to system deployment is crucial and can highly depend on different contexts, in relation to different environmental conditions. The objective of this work is to provide a simulation-based approach for the identification of NFR conflicts in different contexts for such systems. The identified conflicts can help the system designer minimize the impact and avoid failures resulting from the negligence of NFR conflicts. The simulation results are useful to infer and evaluate the different conflicts between NFRs and to study the impact of different contexts on the requirements themselves. The adopted methodology is easily reproducible in different development scenarios.
