- class pm4py.statistics.traces.cycle_time.pandas.get.Parameters(value)[source]
Bases:
enum.Enum
An enumeration.
- CASE_ID_KEY = 'pm4py:param:case_id_key'
- START_TIMESTAMP_KEY = 'pm4py:param:start_timestamp_key'
- TIMESTAMP_KEY = 'pm4py:param:timestamp_key'
- pm4py.statistics.traces.cycle_time.pandas.get.apply(df: pandas.core.frame.DataFrame, parameters: Optional[Dict[Union[str, pm4py.statistics.traces.cycle_time.pandas.get.Parameters], Any]] = None) float [source]
Computes the cycle time starting from a Pandas dataframe
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
df – Dataframe
parameters – Parameters of the algorithm, including: - Parameters.START_TIMESTAMP_KEY => the attribute acting as start timestamp - Parameters.TIMESTAMP_KEY => the attribute acting as timestamp - Parameters.CASE_ID_KEY => the attribute acting as case identifier
- Returns
Cycle time
- Return type
cycle_time
