There are well-known theoretical examples that show that stability constraints in nonlinear model predictive control (NMPC) are necessary in order to guarantee closed loop stability. In this paper it is shown that these stability constraints, derived from theory, are also essential in practice. In particular, an experimental study is carried out on a four(More)
Internet of Things-aware process execution imposes new requirements on process modeling, that are outside the scope of current modeling languages. Internet of Things (IoT) devices may vanish, appear or stay unknown during process execution. Therefore, design time process resource allocation is not feasible. Additionally, device capabilities are only(More)
Cyber-physical systems (CPS) represent a new class of information system that also takes real-world data and effects into account. Software-controlled sensors, actuators and smart objects enable a close coupling of the cyber and physical worlds. Introducing processes into CPS to automate repetitive tasks promises advantages regarding resource utilization(More)
We present PROtEUS--a context-adaptive workflow engine for smart environments. To cope with the heterogeneity and dynamic nature of ubiquitous systems, PROtEUS extends existing workflow engines by introducing dynamic sensor event streams, IoT services and humans as first class citizens. These resources can be selected at runtime based on their capabilities(More)
