how to find (reference) Token in script?

I want to write a script, the goal is to find a Token object (has been created) in the model, then transfer its length to string, and return it, how can I do.

Software Version:

FlexSim 20.1.0

flexsim 20.1.0 script token

Hi @laijunyi1996,

It's hard to know how to help without looking at your model. To receive a more accurate solution, please post your model or a sample model that demonstrates your question.

Proprietary models can be posted as a private question visible only to FlexSim U.S. support staff. You can also contact your local FlexSim distributor for phone or email help.

Thanks.

I hope my model works like this

queue1: inventory

queue2: waiting line

branch: generate demand（random number of box）

first, operator1 take 10 groups of boxes from queue1 into queue2, then flexsim send the demand quantities of each branch to python , then python calculate the best transport route (VRP problem), the drivers transport box along given route.

so I want to achieve that flexsim can collect the quantites of each demand , then spell them in to a string, then send it to python. this requires that flexsim locates these tokens (GroupOfItems1234), return its quantites in script.

If you have a token for each box/item then you can create a pointer to the token that created it (or was created by an item event). For example in the Create Objects activity you can add the pointer like this:

Using the pointer you can then get the unique id from the item reference using:

Token mytoken=item.token;
int myid=mytoken.id

or

item.token.as(Token).id

This way the token has a label 'item' and the item has a label 'token' so they can find each other without you having to search through all the tokens.
