An Execution System for Self-healing Workflows in Cyber-physical Systems

Abstract

Within the Internet of Things software controlled sensors, actuators and smart objects enable a close coupling of the cyber and physical worlds. Introducing workflows into these cyber-physical sys- tems (CPS) promises advantages regarding automation, resource utilization and flexibility of control systems. In this work, we present PROtEUS – an integrated system for process execution in CPS. PROtEUS integrates components for event processing, data routing, dynamic service invocation and human interaction. It is the basis for executing self-healing and model-based workflows that assure cyber-physical consistency by applying the MAPE-K feedback loop.
