Executing Discrete/Continuous Declarative Process Specifications via Complex Event Processing
For cyber-physical systems requiring integration of discrete and continuous data, this work provides the first real-time execution framework for hybrid declarative process specifications, addressing a key limitation of existing BPM approaches.
This paper introduces a novel execution architecture based on Complex Event Processing (CEP) that enables real-time execution and enforcement of hybrid declarative process models combining discrete events and continuous sensor data, bridging the gap between specification and operational control.
Traditional Business Process Management (BPM) focuses on discrete events and fails to incorporate critical continuous sensor data in cyber-physical environments. Hybrid declarative specifications, utilizing Signal Temporal Logic (STL), address this limitation by allowing constraints over both discrete events and real-valued signals. However, existing work has been limited to monitoring and post-hoc conformance checking. This paper introduces a novel execution architecture based on Complex Event Processing (CEP) that enables the real-time execution and enforcement of hybrid declarative models. Our three-layer approach integrates STL-inspired predicates into the execution flow, allowing the system to actively trigger activities and enforce process boundaries based on continuous sensor behavior. This approach bridges the gap between hybrid specification and operational control.
