Handling Human Factors in Integrated Systems Engineering

In this paper we focus on architectural concepts for complex sociotechnical systems and advanced pervasive applications which have to be highly context aware. First we claim that there is a great need for model-based reasoning about systemic properties concerning questions of system design and the definition of long-term management policies. After this we take our starting point from formal methods, requirements engineering, and software architecture. We provide special extensions for these methods which are well-suited for the special challenges of sociotechnical systems: adaptive behavior and the behavioral relevance of cognitive parameters. We maintain the visual style of modeling concepts as known from software architecture and provide elements of an easy to use notation for reasoning about the features of specific situations. Finally we provide concepts to deal with uncertain system behavior and human error.
