Break Transporter

Hello,

In my system, I would like to stop the transporter in front of the Processor1 during process time

is it possible?

Means: the transport will put the box in the Processor 1, then it will wait until the exit of box to take it.

I can do it in other ways, the Queue 3 connected with the transporter, so action close output (Queue3) if the processor 1 in operation, if not open output

Thank you in advance for your help

Here's how you require the transporter to stay at the processor during the process time. Try this and see if it does what you're looking for. If not, let me know and we'll find an alternative approach.

1) Open Processor1 properties.

2) Find the "Use Operator(s) for Process" box. Check this box.

3) Make sure that the "Pick Operator" is set to the correct center object. In this case, it will be "current.centerObjects[1]" because the transporter is the first item with an S-Connect to Processor1.

Here's a visual to help:

Thank you for your reply.

Your proposition is not exactly what I'm looking for, because the transporter to stay at the processor during the process time, but it’s does not take the box back directly after it’s exit.

My problem,means: the transport must do three successive tasks with the processor 1 are put the box,wait during the process time, take the box.

Thanks!

To clarify, you want the transporter to stay with the object from Processor1 all the way to the last queue and then go back to Queue1 for a new object and repeat the process?

Thank you for clarification. I was not sure if I had understood correctly initially. What you've described can be modeled using Process Flow. Are you familiar with this facet of FlexSim?

In your model, I've created a Process Flow that should behave as prescribed. When items enter Queue1, a token is created, which then acquires Transporter1. Transporter1 will take the item from Queue1 to Processor1, wait for the process to finish, then take the item to Queue2. After this is complete, the Transporter is released and can be acquired by the next item's token.

Here is a supplemental visual to help explain:

Please review the model I've attached to verify that it behaves correctly up until Processor2. And let me know if you have questions about Process Flow.

Hello,

Not at all, I do not know Process Flow, because I am a beginner user of FlexSim, but the process flow represened (supplemental visual) is quite correct and exactly what I'm looking for.

The model that you sent me does't work, it displays this error!

thanks

It appears that the error might be happening because the items never made it to the sink, so things were getting congested. I've updated the model and it runs through to completion (until all items are processed through both processors). Let me know if this is still throwing errors, because it there might be more to the problem.

Updated model: 13536-akkachetestmodelprocessflow-1.fsm

I had a co-worker open the file and it worked for him. I wonder if it's a limitation of the student license that I'm not aware of. So the model doesn't run at all for you? Even if you close the error window, reset it, and run it?
