Decide which Process Flow use based on Parameter

Hello,

Follow attached a internal logistic model that I created using Process Flow, which operators collect boxes from warehouse and delivery them at manufacturing.

There are 3 blocks of Process Flow, and I only want to run one at a time:

Blue- Process without cart and one piece flow (Ignore in question 1).

Red- Process with cart and one piece flow.

Green- Process with cart and batch.

I have 2 questions:

1) I am manually enabling all sources of the block and disabling the others, but I need to automate it so i can use Experimenter, I tried to place a decide condition on top of the blocks and based on a parameter "Batch", if batch is true, use the Green block, else use Red. (Ignore Blue block here). How can I do that? Or is there a better way?

2) About the Blue block, after the first cycle, the operator jumps to a delivery position of the last cycle before collecting the box on warehouse (Simulation time: 800 seconds). I've read on this forum that Its needed to Move the operator to model and reconnect the operator to the node, but Its not working, what did I do wrong?

Thank you in advance!

1) There are numerous ways to do this. As you say, one possibility is to use a Decide activity that determines where to send the token based on a parameter.

From the current state of your model a quick solution would be to make the created quantity depend on the model parameter. The expression below multiplies the quantity (1) by either 1 or 0, depending on whether the comparison is true or false. Only if the parameter has the right value a token will be created.

The most complex (but not necessarily best) option would be to automate the enabling/disabling of the various sources through code in the parameter's On Set trigger.

All of these options are demonstrated in some way in the attached model.
