Petri Net In subject area: Computer Science A Petri net is a graphical representation used to model concurrent interactions among different components of a system. It consists of nodes representing transitions, places representing preconditions, and directed arcs connecting places and transitions. When ...

Timed-arc Petri nets (TAPN) are a well-known time extension of the Petri net model and several translations to networks of timed automata have been proposed for this model. We present a direct, DBM-based algorithm for forward reachability analysis of bounded TAPNs extended with transport arcs...
As has been mentioned in the previous section, Petri nets are one of mathematical formalisms which can be used to model and analyze biological systems. They have a structure of a biparted, directed graph with weighted arcs. Formally Petri net can be defined as a 5-tuple \(Q = (T,P,F...
However, we need a way to formally relate responses and other operations in the web service under analysis so thus we can relate the components of the Petri net that we iteratively create when parsing the OpenAPI specification. Furthermore, the OpenAPI document must accurately represent the ...
The focus is on the detection of conflicts and confusions at the net level, but this might require to overspecify a given SPN model. The problem becomes even more critical when reward processes of interest derived from the basic underlying process are considered. Typical examples are state-...
