  Supporting Diagnosis of Requirements Violations in Systems of Systems
  

  Author(s):

  Michael Vierhauser, Jane Cleland-Huang, Rick Rabiser, Thomas Krismayer, Paul Grünbacher

  Abstract:

  Industrial software systems are often systems of systems~(SoS) whose full behavior only emerges during operation. They therefore require monitoring techniques to observe systems and detect deviations from their requirements. The focus of existing monitoring approaches, however, is mainly on detecting violations of expected behavior, while support for diagnosing violations is typically limited or even neglected. Diagnosis is particularly challenging in SoS due to their technological heterogene…

  A comparison framework for runtime monitoring approaches
  

  Author(s):

  Rick Rabiser, Sam Guinea, Michael Vierhauser, Luciano Baresi , Paul Grünbacher

  Abstract:

  The full behavior of complex software systems often only emerges during operation. They thus need to be monitored at run time to check that they adhere to their requirements. Diverse runtime monitoring approaches have been developed in various domains and for different purposes. Their sheer number and heterogeneity, however, make it hard to find the right approach for a specific application or purpose. The aim of our research therefore was to develop a comparison framework for runtime monitor…

  Monitoring CPS at Runtime A Case Study in the UAV Domain
  

  Author(s):

  Michael Vierhauser, Jane Cleland-Huang, Sean Bayley, Thomas Krismayer, Rick Rabiser, Paul Grünbacher

  Abstract:

  Unmanned aerial vehicles (UAVs) are becoming increasingly pervasive in everyday life, supporting diverse use cases such as aerial photography, delivery of goods, or disaster reconnaissance and management. UAVS are cyber-physical systems (CPS): they integrate computation (embedded software and control systems) with physical components (the UAVS flying in the physical world).UAVS in particular and CPS in general require monitoring capabilities to detect and possibly mitigate erroneous and safet…

  Visualization support for requirements monitoring in systems of systems
  

  Author(s):

  Lisa Maria Kritzinger , Thomas Krismayer , Michael Vierhauser, Rick Rabiser, Paul Grünbacher

  Abstract:

  Industrial software systems are often systems of systems (SoS) whose full behavior only emerges at runtime. The systems and their interactions thus need to be continuously monitored and checked during operation to determine compliance with requirements. Many requirements monitoring approaches have been proposed. However, only few of these come with tools that present and visualize monitoring results and details on requirements violations to end users such as industrial engineers. In this tool…
