Extending SafeConcert for Modelling Augmented Reality-equipped Socio-technical Systems*

With the emergence of new technologies such as augmented reality in socio-technical systems, traditional risk assessment methods may fail to have a comprehensive system modelling, because these technologies extend human's capabilities, which might introduce new types of human failures caused by failing these extended capabilities and new types of faults leading to human failures. Current state-of-the-art modelling techniques do not contemplate these capabilities and augmented reality-caused faults leading to human failures. In our previous work, we proposed an extension for modelling safety-critical socio-technical systems, to model augmented reality-extended humans by using a taxonomy that contains AR-specific human's failure behavior. In this paper, we continue our extension by investigating faults leading to human failures including faults because of augmented reality. Our extension builds on top of a metamodel for modelling socio-technical component-based systems, named SafeConcert. We illustrate our extension on two fictitious but credible systems taken from air traffic control and rail industry. In order to model augmented reality-equipped socio-technical systems, we need to consider human and organization as parts of the system and augmented reality as a technology used in the system.
