I'd like to record entry and exit time for each batch in the system. Entry time of a batch means the time 1st unit in a batch enters the system and Exit time of a batch means last unit of a batch exits the system.
Currently, I only can record entry and exit time of each object. How can I add "Batch" as 1 more constraint to be considered? And how can I take 1st and last unit of a batch for consideration only?
Thank you.entry and exit times trial.fsm
