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]
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.
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.
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.
It consists of artifact-centric process model, process view model, a set of consistency rules, and the construction approach for building process views. The formal model of artifact-centric business processes and views, namely ACP, is defined and used to describe artifacts, services, business rules that control the processes, as well as views.
Logical connector In the event-driven process chain the logical relationships between elements in the control flow, that is, events and functions are described by logical connectors. --TheFamilyBusiness 10:49, 17 February 2016 (UTC)
Before event-driven SOA, the typical SOA platform orchestrated services centrally, through pre-defined business processes, assuming that what should have already been triggered is defined in a business process. This older approach (sometimes called SOA 1.0) does not account for events that occur across, or outside of, specific business processes.
