Event
Event life cycle
Different event lists
To make the simulation faster two event types were introduced a logger and a short term logger.
Short term logger
Task: decision-making basis for controller strategies
Label: Label.ShortTermLogger.value + "0"
short term logger offers the possibility to store specific events from the past to use them for a controller strategy.
An example would be storing the last events related to a position to determine the waiting time of parts
Logger
Task: saving of events in a csv or data base
Label: Label.Logger.value + "1"
After the execution of the event all events are mirrored (generated by Event_logger) and stored in the logger. If the logger 2000 contains events, the events are stored in a csv or database and no event_logger items are deleted but always overwritten. Event_logger Connections can be recognised in the ontology with the ending “_logger”
Event list
Task: Saves all future events of the simulation
Label: Label.EventList.value + “0”
