Connect transporter to queue

[ FlexSim 16.0.8 ]

Hi everyone

I would like to add a transporter to my model. It should represent an external supplier that delivers a certain number of units (I will write the logic that defines the exact quantity in the item's triggers) at specific time intervals. How can I connect a transporter to an existing queue?

A truck, plane (or anything representing cargo in general) could also be used to represent my external supplier.

Best regards

Pieter

@Pieter Cecat The transport is connected with a centerport connection to the object that has to deliver the amount, not to the one receiving it. On the queue you have check on the checkbox "Use Transport" This can be done on the Quick Properties or via the flow tab on the object itself. You can find more explanation in Lesson 2 of the Tutorials. If you want to change the 3D shape (in a truck or a plane) of your object you can best use the TaskExecuter because that object has no extra movements.

I agree with what @steven.hamoen said. You can use queues and their batch size to deliver a specific number of items. Don't forget to set the number of items on the transporter to the same amount. If you need to change the amount delivered, you can change both of those variables with the tree (setvarnum) and adjust them as you run the model. I made a quick model to show what it can look like. fixed-time-transport.fsm

@steven.hamoen @Kaspar Chabot

The system I have now looks as follows:

I do however want to control the release quantities at the source. To do this I defined a global lookup table. Depending on the month, as well as scenario, a different quantity should be released. I know how to code this. The problem however is that the open/close output commands don't seem to work on a source. How can I make sure the correct 'quantity' is released as some sort of release schedule at predefined times (monthly)?

Note: the transporter can then pick up the entire queue content and transfer it to the other queue all at once.

Thanks in advance for your help.

You might try using the open/close output commands on one of your Queues for this kind of situation. They handle those types of commands better.
