Operator pick specific item from conveyors

Hello,

I am new to FlexSim and still figuring out how FlexSim works.

In the model below, I have 3 conveyors that connect to each other and the last conveyor connects with a separator. Also, I have 2 decision points where operators can pick up the items from the conveyors. Each decision point has 4 operators.

There are 3 items that go through the conveyor: red, blue, and green. I want the operators to pick up the blue and green items on every decision points I build and move them to the floor storage located on the left and right of the conveyors. Other than that, I want to let the red items go through the separator.

I tried to build the model with a General Process Flow but it didn't go as I wanted, the red items ended up going to the Red_CB (floor storage) first, and the operator must pick it up one by one to the separator.

Is there any possible way to fix this? I uploaded the model and the picture below, thank you very much.

Did you upload the correct model since this one give an error immediately.

Which is happening since:

Model.find("organik hasil conveyor")  

evaluates to NULL (but you should probably be unloading to an entry transfer rather than the conveyor directly). You can test expressions like that work by running them in the script console and looking at the result.

Rather than 'figuring out' FlexSim you should go through the tutorials.

Hi, thank you for answering, and I'm sorry for the late reply.

And yes, unfortunately, I uploaded the wrong file as I changed the name of the floor storage so the model didn't run well. Let me attach the correct one below.

RPM.fsm

I also tried what you suggested by changing it to an entry transfer and it works, but the operators still need to pick up and move it to an entry transfer.

Is there any other way to let the red items go through the conveyors without being picked up by operators?

It's not doing anything you haven't told it to. If you want to let some items flow through then don't stop them / create an operator job. Use an Decide activity to determine that based on the item.

As I said, you should do the tutorials.
