Releasing a batch based on a minimum number of token

Hi everyone,

I have a model working with Process flow.

At time 0, Supermarket fullfilled, and orders arrived. I pick parts in the supermarket and released "kanban" to the prduction area.

as a trigger to produce, I used "batch" function to release a certain amount of cards in once to avoid to process each part individually. So in my case, batch of 6.

But, I realized that's not how it should work, due to the fact that if I have 7, production should receive the 7 orders. (now, 1 batch of 6 released and the 7th stay in the batch activity waiting next day order)

How to do with a "minimum" batch ? or to program a decide or custom code to work with quantity of token?

Thanks for your info back.

Software Version:

FlexSim 20.2.2

flexsim 20.2.2 custom code conditional decide batch size kanban

Hello @Armand J

The Batch activity doesn't seem to allow that kind of logic. It would be helpful to see your model to find an alternative solution. Could you post your model or a model that demonstrates what you are trying to accomplish?

As you describe it. Add another process that does what you want. If your batch activity lets exit a token and there is waiting another token, you preempt this token batching activity.

On Event create token activity > get tokens of batch activity as an array in custom code> decide if array is not empty > run sub flow > preempt every single token of the array to be in next activity of their process > finish.

Hi @Jörg Vogel, @Jeanette F,

Thanks for your answers and interest to my question.

With a direct support, I succeed to do that, please see below the way.

Batch quantity increased to inachievable level (here 100), using "Use Max Wait Timer" to release Batch with a criteria "collected >= 6".

This was working fine but my trigger for production have a different quantity per P/N, this was not sufficient.

The next step is to use a Table to get different condition level in the criteria, as "collected >= Table("BatchperType")[token.Try.TypePart]["Batch_min"]"

Now, after a time of 20s, if my number of token per type achieved the required minium, my batch moved to next step.

Thanks @Clair A for support
