Model-based development of QoS-aware reconfigurable autonomous robotic systems

Complex software systems need to be dynamically reconfigured due to run-time variabilities, such as environmental conditions, workload fluctuation and resources availability. To analyze these autonomous systems it is necessary to put in place methodologies suitable to deal with the diversity of runtime changes during the system evolution. This paper proposes a methodology for modeling the variability and the associated Quality-of-Service (QoS) characteristics of reconfigurable software systems. As a case study, we present the development of a navigation system for autonomous robots that perform logistics tasks.
