Unfortunately, you can't manually change the number of resources while your model is running, but you can assign logic that will listen to other variables, such as an Array Size. Here's what that menu looks like:

I'm not sure that resources is the best option for what you're trying to keep track of, though. If you're keeping track of cars in your system, it might be better to treat the cars as flow items. Just a suggestion, though.

I have taken the suggestion , but I don't know is it valid to use a flow item(car) to "transport"

another flow item(person) ?

and with the same setting , the token just stacked on some flow , but the othe didn't.

i have update the fsm file in the question . thanks

I may have been misleading. Let me try and clarify.

Will you always have the same number of shared cars? If so, you could add them to a group and then reference the group in the resource. It would look like: Group("Shared Cars"). By doing this, only the cars available will be able to be acquired. If there aren't any available, no cars will be acquired.

Only if you want the number of cars to vary (i.e. cars are created and destroyed) would it make more sense to treat them like flow items.

That really helps! thanks!
