Multiple process overlapping in the same station


The scenario is: Human worker loads 1 part into a nest, as soon as the worker complete work, one in station operation start (simply use delay to model this duration); After the worker goes to pick another part and load the part;

There are muliptle of this process (load → in station process). They are not started together, but the time slots are overlapped.

After all “in station operations” completed, all of the part will be unloaded from the station together.

My question is: do we need to model this scenario using multiple process node: each “load->in station process” is put into 1 process node, and the unload actions in another node?

Thank you!
