class pm4py.statistics.traces.cycle_time.log.get.Parameters(*values)[source]#

Bases: Enum

TIMESTAMP_KEY = 'pm4py:param:timestamp_key'#
START_TIMESTAMP_KEY = 'pm4py:param:start_timestamp_key'#
pm4py.statistics.traces.cycle_time.log.get.apply(log_or_trace: Trace | EventLog, parameters: Dict[str | Parameters, Any] | None = None) → float[source]#

Computes the cycle time starting from an event log or a trace object

The definition that has been followed is the one proposed in: https://www.presentationeze.com/presentations/lean-manufacturing-just-in-time/lean-manufacturing-just-in-time-full-details/process-cycle-time-analysis/calculate-cycle-time/#:~:text=Cycle%20time%20%3D%20Average%20time%20between,is%2024%20minutes%20on%20average.

So: Cycle time = Average time between completion of units.

Example taken from the website: Consider a manufacturing facility, which is producing 100 units of product per 40 hour week. The average throughput rate is 1 unit per 0.4 hours, which is one unit every 24 minutes. Therefore the cycle time is 24 minutes on average.

Parameters:

  • log_or_trace – Log or trace

  • parameters – Parameters of the algorithm, including: - Parameters.START_TIMESTAMP_KEY => the attribute acting as start timestamp - Parameters.TIMESTAMP_KEY => the attribute acting as timestamp

Returns:

Cycle time

Return type:

cycle_time
