Items choosing Queues based on waiting time

[ FlexSim 23.2.2 ]

Hey there, thanks for any help in advance!

I´m trying to build a model which represents a cafeteria. The people are spawning to chosen times with two preferred foods, of which one of them they`d like to get. We realised this with labels. Each guest got two labels, Label1: Preference 1 | Label 2: Prefernece 2. This way the choose between different waiting queues.

The customers are supposed to move to their specific preference 1. In case they need to wait more than 5 minutes, they`re supposed to move to their second preference. If they wait another 5 minutes at the second spot, they`re leaving the scene.

I´m stuck and would appreciate any ideas to solve the problem. I´m open to use the modeler, processflow or flex script.

All the best

Paul

Hi @tall_pauhl,

It's hard to know how to help without looking at your model. To receive a more accurate solution, please post your model or a sample model that demonstrates your question.

If your model contains sensitive information, you could first toggle your post as private using the "make private" option under your question's "gear" menu. Private questions are visible only to site moderators. You can also contact your local FlexSim distributor for phone or email help.

Hey @Kavika F, I appreciate your comment. Here`s the actual version of the model. 202312015_V1_TrynError_Liste_Kassenoeffnung.fsm

@tall_pauhl, here's what I gleam from your model so far.

You're making a bunch of different types of "meals" and running them through the first set of processors. Then they wait idle for a person to pick them up. That person is created from a source with a schedule of making people at specific times of day. They have no "preferences" like you've described. If you want to add a preference label for them, you can do that with an On Creation trigger.

Additionally, if you want them to go to specific preferences, you'll have to try pushing them to a list where the queues can pull them. While on the list, the queues can look at people with their specified labels and pull those people to take that tray of food. If the person doesn't get pulled for 5 minutes, then you can take them off the list and try pushing them with their second label instead.

Hey @Jason Lightfoot we are still working on the model and did not succesfully implement the logic yet.

In case for needed help I`ll come back to this thread.

Much appreciated.

I would have the people pull their first preference from a list of ready meals with a timeout that takes them to pull either of their preferred two meals from the list. Pretty simple.

Good question! Directing items better with the help of a decision node or custom logic using a calculated attribute of queue waiting times can help. You can also use this resource as a rest-break during the tests when you find it conveniently useful!
