pm4py.algo.simulation.montecarlo.utils.replay.get_map_from_log_and_net(log, net, initial_marking, final_marking, force_distribution=None, parameters=None)[source]#

Get transition stochastic distribution map given the log and the Petri net

Parameters#

log

Event log

net

Petri net

initial_marking

Initial marking of the Petri net

final_marking

Final marking of the Petri net

force_distribution

If provided, distribution to force usage (e.g. EXPONENTIAL)

parameters
Parameters of the algorithm, including:

Parameters.ACTIVITY_KEY -> activity name Parameters.TIMESTAMP_KEY -> timestamp key

Returns#

stochastic_map

Map that to each transition associates a random variable
