I have a model in process flow with include graphics with full wagons then I unload and I put empty wagons for the statistics i have as the train is always full. is there any trick to change the status and collect the statistics with empty wagons ?
Hello Javier,
Here is an example: 2022-08-26 Train with empty or loaded wagons.fsm
If the state is travel loaded but the 1st wagon is empty, I override the train state to travel empty:
Note that with that behaviour the train will have the travel empty state in both situations below:
- when the train travels alone without any wagons
- when the train travels with empty wagon(s)
All objects use something called a Categorical Tracked Variable to record how long they have been in each state. You can make a Categorical Tracked Variable on a label on a token, and set it to any state at any time. That way, you won't have to fight against the object as it tries to change states.
Then you can make a stats collector that records the time in each state, and you can also make a chart that points at the column set.
Here's a demo model: CustomStatePieDemo.fsm
Here are some key points:
- I added an empty state table with some example states.
- I made a token with a categorical tracked variable on a label
- The Categorical TV gets set to random states
- The stats collector creates a column for the token id, a column for the utilization, and one column for every state in the state table.
- The pie chart points at the table from the stats collector.
