Is it possible to move stations along a conveyor?

I need to model a continuous moving assembly line, where operators work on a moving conveyor. In particular, i have 3 stations and 3 operators. When the operator finishes to work on a task, goes down the conveyor and reaches the next coming task.

My FlexSim version is 16.0.1.

Thanks for your help,

Ilaria.

Hi @Ilaria B

Do you have an example of the model or picture of the process you could upload? This would help us understand your process better.

Thanks

First of all thanks for your answer @Isaac Litster, i'm sorry but I have problems to upload the model. My idea is to have the operator and the object to assembly flowing on the same conveyor, so the conveyor transport both and the operator works while the conveyor is moving. I hope the problem it's clearer, if is not i will try to charge a video or an image.

Thank you very much!

@Ilaria B

Conveyor object is fixed but the stations are generally fixed on the conveyor. They can't be moved on the conveyor. When the conveyor has three stations and three operators, three operators can do the task in each station walking on turn-around three stations. What is your exact meaning?

When you express exactly your issue, you can get the solution of it. So you need to upload your model.

@Isaac Litster @Seung Yong Seo I found this 2 images in internet to explain better my situation. I need to model an assembly line where operators flow on the same conveyor of the piece to assembly.

Thanks!

Take a look at this model and use it as a template for what you are doing, you can edit the Flow Item station to make it look like whatever the operators are supposed to be working on.

Hi @Joshua S, thanks for you answer. I would like to know if is it possible to use the processor like a normal station (with flowing items in the processor following a certain arrival distribution) to calculate its performances while it's moving on the conveyor.

Another question, is it possible to insert a Station instead of a processor on the moving plane you created? I mean a normal station (the squared orange one avaiable in the library) with all its funcions?

Thanks

The normal orange stations lose their purpose with the model I sent you, stations are only used directly on conveyors. The processors in your model can act like normal processors, In the flow item bin you can copy and paste a source and a sink into the custom flow item processor.

Hi @Joshua S, I tried but my situation is different. The object i want to process in the processor come from an external queue, I can't create it in the plane of the custom flow item. In the OK4 model attached there's the situation i would like to have, not with fixed stations but with moving stations and operators along the conveyor. In the OK3 model i tried to replicate your model, but I'm not able to unload the box in the processor.

Thanks for your answers,

Ilaria
