All pallet move at a time on main line

Hello all,

 

I have applied one object process flow so that all pallets will move at a time. but model stuck after some time

I have applied previous answer logic here.

but here blue station is combining stations i did through process flow.

all working fine but once i applied logic to move all pallet at a time using object process flow then model stop.

please help me to find out the solution

The "Wait until all stations done" activity is not linked to the list.

The logic that waits until all pallets can continue works (let's call it MAST (move at same time)) by waiting for the OnProcessFinish event of the stations. This means it doesn't work with the other logic in the model in two ways:

1. The stations where the items are loaded have a process time of 0. As far as the MAST logic is concerned, the pallets can immediately continue despite not having been loaded yet. To fix this, give both stations a tiny processing time and stop the stations instead of the items in the Process Flow that controls the loading.

2. Some stations only process every other item. The process event not firing means the MAST logic gets stuck. Change those stations to process every item and instead return 0 as the process time for every other item. The XYZ in the if-condition is either a 1 or a 0, depending on whether the first or second arriving item should be processed.

int counter = current.labels.assert("EOI_Counter", 0).value;
current.EOI_Counter += 1;
if(counter%2 == XYZ)
{
	return Table("Cycle time")[current.name][item.subnodes[1].Type];
}
return 0;

Hello @moehlmann_fe ,

Thank you so much for your quick support.

I applied what you said. 1. link list 2. CT 1 sec for station.

but some stations have logic which we not able to change because that logic i want as is it. like you explain in 2 point. 

I am sharing updated file but it's stuck at yellow color station

What you didn't do is stopping the stations in the loading logic instead of the items.

And the logic of the other stations needs to be changed if you want to use the MAST logic with them. Whether the item is processed with a process time of 0 or not at all doesn't make any difference. The only thing that happens is that the stations triggers some additional events and enters the processing state for 0s.

Hello @moehlmann_fe ,

You changed the yellow station logic and blue station logic.

But they are mandatary logic applied. do you have any other solution.

All pallet move at a time on main line” seems to be a concept of synchronization and streamlined process. In the same way, NCERT Books VedaAcademy ensures that all subjects, chapters, and study resources move together in a systematic flow for students. Just like pallets on the main line reach their destination without confusion, our online education platform helps learners access NCERT Books in an organized manner, saving time and improving efficiency.

I swapped the order in which the green stations process pallets by accident. Other than that I did not change how they function. In the attached model I deactivated the object to move all pallets at the same time and the resulting movements are the same as in the model you originally uploaded (also with the MAST logic deactivated).

Once the logic gets activated again it changes of course, as pallets wait at each station until all stations are also ready to continue. If that is not what you want then why do you try to implement that logic in the model?
