Abstract
This paper presents a possible refinement of Business Process Model and Notation (BPMN) Gateway activation concept for non-event-based gateways. The core refinement is the concrete formal definition of upstream token concept and calculation of the enabledness of an inclusive gateways (or also Or-Join) using modified Dijkstra’s algorithm. The introduced algorithm for upstream token calculation considers also situations where two or more gateways are mutually dependent.

Note that the direction of edges \( e \in {\mathcal{E}} \) is opposite to the direction of sequence flow \( s \in {\mathcal{E}}_{sf} \).
