As such it forms the core technique for modeling in ARIS, which serves to link the different views in the so-called control view. To quote from a 2006 publication on event-driven process chains: [2] An Event-driven process chain (EPC) is an ordered graph of events and functions. It provides various connectors that allow alternative and parallel ...
Event-driven process chains (EPC) and BPMN are two notations with similar expressivity when process modeling is concerned. [8] A BPMN model can be transformed into an EPC model. Conversely, an EPC model can be transformed into a BPMN model with only a slight loss of information. [9]
Example of a more complex EPC diagram (in German). An event-driven process chain (EPC) is a type of flow chart for business process modeling. EPC can be used to configure enterprise resource planning execution, and for business process improvement. It can be used to control an autonomous workflow instance in work sharing.
The event driven execution model allows an explicit specification of the execution order of function blocks. If necessary, periodically executed applications can be implemented by using the E_CYCLE function block for the generation of periodic events as described in Annex A of IEC 61499-1.
ARIS Express is a free-of-charge modeling tool for business process analysis and management. It supports different modeling notations such as BPMN 2, Event-driven Process Chains (EPC), Organizational charts, process landscapes, whiteboards, etc. ARIS Express was initially developed by IDS Scheer, which was bought by Software AG in December 2010.
Muller et al. [8] also introduced the framework for the data-driven modelling of large process structures, namely COREPRO. The approach reduces modelling efforts significantly and provides mechanisms for maintaining data-driven process structures. Another related thread of work is the use of state machines to model object lifecycles.
From these events the monitoring system may infer a complex event: a wedding. CEP as a technique helps discover complex events by analyzing and correlating other events: [5] the bells, the man and woman in wedding attire and the rice flying through the air. CEP relies on a number of techniques, [6] including: Event-pattern detection; Event ...
Sequence diagrams are sometimes called event diagrams or event scenarios. For a particular scenario of a use case, the diagrams show the events that external actors generate, their order, and possible inter-system events. [2] The diagram emphasizes events that cross the system boundary from actors to systems.
