Class PNUnfoldedSimulator

java.lang.Object

org.processmining.plugins.stochasticpetrinet.simulator.PNSimulator

org.processmining.plugins.stochasticpetrinet.simulator.PNUnfoldedSimulator

public class PNUnfoldedSimulator
extends PNSimulator

Idea: Use one unfolded model for multiple traces. Same semantics, but different log (we need to treat each "lane" in the model as an instance). The lanes are dependent by resource connections.

There is only one big run of the model emitting all the traces.

Performs a simple simulation of the Petri net (mostly used for StochasticNets, but can also simulate a PN without stochastic annotations) See #simulateTraceEnd(PetrinetGraph, Semantics, PNSimulatorConfig, Marking, Date, int, Map, boolean) for an implementation that does not generate costly XIDs required for XES log files.

Parameters:

petriNet - PetrinetGraph the model

semantics - Semantics the semantics

config - PNSimulatorConfig the configuration PNSimulatorConfig

initialMarking - Marking the initial Marking

traceStart - long the date time to start the trace

constraint - long the date time that all simulated events should be greater than

i - int trace id

useTimeConstraint - boolean stores whether created events are constrained to be later than traceStart

finalMarking - Marking a final marking can be set to terminate the simulation, when it is reached... ignored, if null

Returns:
