- KonferenzbeitragAn Execution System for Self-healing Workflows in Cyber-physical Systems(Software Engineering 2017, 2017) Seiger, Ronny; Huber, Steffen; Schlegel, ThomasWithin 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.
- KonferenzbeitragA Framework for Self-adaptive Workflows in Cyber-physical Systems(Software Engineering and Software Management 2019, 2019) Seiger, Ronny; Huber, Steffen; Heisig, Peter; Assmann, UweWorkflows can be a useful means to formalize and enact processes among the sensors, actuators, smart objects and humans in Cyber-physical Systems (CPS). However, the dynamic nature of CPS and their resource constraint entities require the workflows and Workflow Management Systems (WfMSes) to be resilient and self-adaptive to deal with unanticipated situations and exceptions. We propose a generic framework based on the MAPE-K feedback loop to add self-management capabilities to WfMSes in the context of CPS. A case study in the smart home domain shows the general applicability of our framework for workflows and various WfMSes.
