Non-simultaneous tokens ordering according to a given value.

[sara_s2]

Hello,

The received empty bins/totes from several storage spaces (Racks) at point of use must be replenished in the replenishment system in the figure 1 following a priority order fixed by a value SC. When empty bins come to "the replenishment system" they are placed in the 'Rack 1788' by 'ASRSvehicle1792' (figure1). Upon their arrival to this rack, they are pushed to the list "EmptyCUtotes" where their SC value is attributed (figure2). A bin is selected and put on the combiner 2 (figure 1) for replenishment that takes 1 minute. When this bin is replenished and leaves the combiner, the next bin is selected for replenishment. At this level, when there is more than one bin on the rack, we must select the priority one (that has the lower SC value) given that the bins don't arrive at the same time on the rack.

I set the query "ORDER BY SC ASC" in the "Pull from List OPMP" (figure3), but this is not working because bins don't arrive at the same time to the rack. I tried several ways to do this but with no result. @Matthew Gillespie would you please help me to fix this?

Regards.

@sara S2 without having a model to look at it is difficult to know what the exact issue is. However, your approach is correct. You query looks correct. I don't know about your field though. Can you not just have an SC label on each token on the list and then add the label as a field instead of doing a table reference? Doing this would allow you to view the list entries and verify that your field is set up correctly. Then wait until you have multiple list entries and test out your query in the Quick Properties to make sure it is working correctly. That's the best I can do without a model.

@Brenton King, thank you for your reply.

In fact, I can't load the model because it is a confidential research work. I know this makes it difficult for you and I am sorry for this. Unfortunately what you recommended is not exactly what I want to have in the model.

Regards.

@sara S2 are you meaning that you have to pull bins in numerical order? 1,2,3,4,5,6? You don't want to just pull the lowest number, you want to pull the next number? Maybe try to explain again please. I don't know if I fully understand.

@Brenton King, thank you for trying to help me. I finally could resolve this. Thank you again.
