Creating Items On A Conveyor At The Simulation Start

[ FlexSim 23.0.3 ]

Hi,

In the attached model, I am creating items on a conveyor at the start of the simulation in order to model the initial inventory stock conditions. The speed of the conveyor is set to a large value and created the items onto the entry transfer. The items are getting created properly but the movement of the items to the downstream machines is not happening correctly. Not sure what's the reason.

Also, I tried a code for setting the item locations on the conveyor on model start which is not working since the items need to enter through the entry transfer for their proper movement inside the conveyor.

Your speed is too big,are you kidding me?

"9999999999999999071569656121801212080692814968920789464627446869617922299624001453201875281811380250249693879805812353226907091680705581859236698853640605134247712274342131878495422251008.00"

How about "9999999999", it is enough i think and it did work.

If you definitely want an item to enter the processor at time 0, then I would suggest to just also create one in there directly.

Hello Arun,

I hope I understood your question right: You want a batch of items to be created directly onto the conveyor/entry transfer, then they're supposed to be moved by the conveyor downstream to the processor, right?

If you set the speed of the conveyor to 99999999... it will be so fast that it's not possible to have a visible animation. Something like 5 m/s worked without a problem.
For the second conveyor I suggest you remove the sub flow in your process flow, because it fixes the position of the item queue and overrides the animation, that's why the incoming item seems to be moving through the other ones instead of lining up with the rest. Also the boxes need to be created in the entry transfer 3

Thanks, I just put a big value only.

At time t =0, I want to have the items packed into the conveyor. That's why I used a large speed.
