pm4py.objects.log.util.interval_lifecycle.to_interval(log, parameters=None)[source]#

Converts a log to interval format (e.g. an event has two timestamps) from lifecycle format (an event has only a timestamp, and a transition lifecycle)

Parameters:

  • log – Log (expressed in the lifecycle format)

  • parameters – Possible parameters of the method (activity, timestamp key, start timestamp key, transition …)

Returns:

Interval event log

Return type:

log

pm4py.objects.log.util.interval_lifecycle.to_lifecycle(log, parameters=None)[source]#

Converts a log from interval format (e.g. an event has two timestamps) to lifecycle format (an event has only a timestamp, and a transition lifecycle)

Parameters:

  • log – Log (expressed in the interval format)

  • parameters – Possible parameters of the method (activity, timestamp key, start timestamp key, transition …)

Returns:

Lifecycle event log

Return type:

log

pm4py.objects.log.util.interval_lifecycle.assign_lead_cycle_time(log, parameters=None)[source]#

Assigns the lead and cycle time to an interval log

Parameters:

  • log – Interval log

  • parameters – Parameters of the algorithm, including: start_timestamp_key, timestamp_key, business_hour_slots
