Hello! I would like to simulate the supply chain in a production workshop.

Hello! I would like to simulate the supply chain in a production workshop. I have 20 machine tools, 3 workpieces and 3 operators to transport from each warehouse to certain machine tools. I don't realize why the operators are not waiting for the process to end and they are moving without the part. For example, when processing P1 to pp_1, Operator_P2 and Operator_P3 move with parts P1 and P3 to pp_1 because there they are to be processed, but when processing is finished P1 to pp_1, Operator_P2 and Operator_P3 move without parts P2 and P3 to pp_2 and pp_3. The paths of each part P1, P2 and P3 are given by P1_process, P2_process and P3_process. Each processor has a set processing time depending on the part type. Can someone help me?

This was because in "Wait for the event" sometimes token.Type1, Type2, or Type3 was assigned to other workpieces. So this logic should be deleted.

In addition in the last part of the logic in blocks "Travel load, travel unload,) token.product should be replaced with token.Type1, Type2 or Type3 and add a connection to sink "lesire"

In attached I send you a model cercetare-ultim_3.fsm

OK. But even with these modifications, after processing the part P1 on the processor pp_1, the part P2 is transported directly to pp_2. This should happen after it is processed by pp_1, and during this time the part P3 should wait for the processing of the part P2. Thanks for the help!

At blocks "Wait for an event" every time when processing was finished at each processor every tokens were released. To solve this problem at "Wait for the event" should need to be added logic that checks product type and release only specific token.

And one last question if you can and don't ask too much, how could I set the operators so that when moving to pps it takes 1 hour, and when moving to vps, tp_1, cp_1 it takes 2 hours. Thank you very much for your help!
