Semantics:

EPC are used for process modelling based on the concept of a bipartite-graph. ePC may be formalized with Petri-nets. An EPC mapping to a Petri-net provides a formalization of EPC, defines the semantics of EPC and enables checks for consistency, soundness etc.

Syntax:

Modelling concepts and functionalities, level of formalism, graphical notation
The main object types are the event and the function. Each process starts and ends with an event. For reasons of readability EPC (lean EPC) may contain also other object types (input or output data; performing organizational units or positions; utilized application systems; etc.), thus leading to so-called extended EPC (eEPC). For practical purposes a filter is defined which contains a predefined set of object types for modelling.
