How do I extract labels of items after they have been packed by a combiner?

Hi,

i want to track the lead times per Type from the point the items leave the first rack to when they enter the last rack. The Problem is, that there is a combiner in the process. After the packing combiner i dont know how to adress the items anymore or at least work with they labels. I am at the point where the items have a entryTime and a exitTime Label. They just have to be interpretated.

Is there an option with the processflow and maybe a simple one with the dashboard?

Maybe someone can help me.

Thank you a lot in advance,

Luca S.

@logan.gold, @sam.stubbs, @zachary.h, @braydn.t,

Can someone help with this one? I'm not sure but I think you can do it with tracked variables but I'm not sure how to really use those. Maybe that could be a training subject?

Thanks.

Here's a model with a chart that shows average lead time by type:

schritt-3-arbeitsmodell_1.fsm

I did it by making a stats collector. The statistics collector listens to the OnEntry of the sink. When that event fires, I add a label called Items, which is an array of all the flowitems in the pallet. Since the stats collector uses Unique Values as its row mode, and I'm using the Items label as the row value, I end up with one row per item on the pallet. Each row records the type, entry time, and exit time.

I did change the ExitTime label set by the floor storage before the sink to not have a space in its name.

I then made a calculated table that gets the

AVG(ExitTime - EntryTime)

and groups by Type. I added a table chart that then shows the result.

@jordan.johnson, got it so far, helps a lot!

But what does the ".up" in the Value of the ExitTime-column of the statistics collector do? "data.rowValue.up.ExitTime"

The “up” property is directing the reference pointer of data.rowValue a level higher in the tree structure to get the label value of ExitTime. I assume data.rowValue is a pointer to a packed item, then the property “up” is pointing to the container item.
