Modeling and execution of event stream processing in business processes

A B S T R A C T

The Internet of Things and Cyber-physical Systems provide enormous amounts of realtime
data in the form of streams of events. Businesses can benefit from the integration of
these real-world data; new services can be provided to customers, or existing business
processes can be improved. Events are a well-known concept in business processes.
However, there is no appropriate abstraction mechanism to encapsulate event stream
processing in units that represent business functions in a coherent manner across the
process modeling, process execution, and IT infrastructure layer. In this paper we present
Event Stream Processing Units (SPUs) as such an abstraction mechanism. SPUs encapsulate
application logic for event stream processing and enable a seamless transition
between process models, executable process representations, and components at the IT
layer. We derive requirements for SPUs and introduce EPC and BPMN extensions to model
SPUs at the abstract and at the technical process layer. We introduce a transformation
from SPUs in EPCs to SPUs in BPMN and implement our modeling notation extensions in
Software AG ARIS. We present a runtime infrastructure that executes SPUs and supports
implicit invocation and completion semantics. We illustrate our approach using a logistics
process as running example.
