Production Planning

Dear Community

I am not sure on how to trigger a production planning production, so that depending on what the customer orders, different objects are made within the same machines / processes.
Here is an example:

1 CB = CarBatch

27x Car Units are needed to make 1 CB.

These Car Units can be made of different Motor and Tire sizes - depending on what the customer orders.

Here is an example of what the processes look like for the tires:

Now, how can I trigger the production according to the customers wishes?
1 CB can be made of 27x different car units - depending on what the customer wants...

Thanks in advance!

@Dominik K This smells like a school project, so I definitively not going to give you a solution ;-)

Tip: Look at processflow and use lists for your materials

or if you keep working in 3D only look at the combiner object

@Dominik K This is how I picture your question. Car Batches are created at a given rate. The Batch is built by splitting into 27 car units and having each of the 27 decide what type they are. Each of those 27 could go through a separate process. When the batch is complete, the CB is notified. I didn't take the time to actually fill out everything in this model or give each type a different set of process steps, but that is the easy part.

Wow, the page refreshed after I wrote around 500 words. Amazing. Here we go again;

Thanks for you answer! The visualization really helps!

Now, when the "Create Car Units" starts, how can I implement the following;

A car unit could be one of these packages;

Car Unit Package S:
Tire S
Motor S
Window

Car Unit Package M:
Tire M
Motor M
Window

Car Unit Package L:
Tire L
Motor L
Window

Car Unit Package Mixed:
Tire S
Motor M
Window

So, if a client now orders a car unit package S, then an M, an S, an L etc. I have to take the right size of an item out of a queue, then put it through the process (e.g. car tire profiling) and so on.
E.g:

The client orders Car Unit Package Mixed.
Item Tire S, Motor M and Window are taken out of Queue
Tire S is going through processes (process-time is shorter than usually bc it's an S)
Motor M is going through processes (normal process-time, since it's an M)
Windows is being processed (process-time always the same, since only one size)
Packaging
Ready for delivery

My goal here is to see how the lead-time changes, depending on different delivery-sequences, wishes from the client / depending from the clients order.

It's very difficult to me, to explain this properly but I really hope this makes sense.
I'd urgently need a way to make my model according to production planning / the clients wishes.

Thank you guys for your help!
Dominik

@Dominik K Please read the best practices of this forum. The idea is that we help people with a question they have about working with FlexSim. So the idea is that you build a model and then ask questions about how to do certain things. This forum is not a place where you can ask: "please build my model". Unfortunately your question looks a lot like that and it doesn't appear you have put a lot of effort in your self. If you need support quick and you would like that somebody builds your model or helps you to a large extent, please contact your local FlexSim distributor and aks him or her to support you.

Hey Steve!

Thanks for your answer. I am not looking for someone who makes my model. It just seems, that such a essential function "Production planning" is not as obvious and easily implemented, as I thought. With the example up there, I just wanted to clarify my question...
