question

Hi @Matthew Gillespie, thank you for your reply.

I tried to perform some changes in the concerned code (Fig1), and it works when I change the number of boxes from 8 to 5 in row 1. But, at row 3, the simulation stops and I get the error in Fig 2. Would you please help me to fix this code correctly?

I want to model a 'Two-bin replenishment system'; where the operator picks items from the first bin (tote1) according to the replenishment planning and when the first bin is empty, the operator picks Items from the second bin (tote2). Items quantities that must be picked are figuring in the global table "QuantityFor Each Type" column 2. The itemlist and the process flow are insuring the achievement of the described process. The custom code in the quantity field of the Run Sub Flow1 activity is telling the operator how much boxes he has to pick. For this, I wrote two cases: Case 1 when value1 (which is the number of boxes to pick) is small than value2 (which is the current tote's boxes amount plus the picked number of boxes) and Case 2 when value1>=value2. In case 2 (exp: number of boxes=9, 9>value2 – value2=8), when the operator picks 8 boxes (loop1) it’s still 1 box to pick. In this time we use loop 2 to add one box. Value4= Value3 =1 and we return 1 box that has also to be picked. Cases and Loops are identified in Figure 1.

When I run this, I get an error in Figure 2. I really don’t know what is the problem in this code !

I hope I clarified what I am trying to do here. I would be grateful if you @Matthew Gillespie could help.

@Matthew Gillespie Thank you very much for your help. This model works perfectly.

Hi @Matthew Gillespie.

I performed some changes in your proposed model (the attached model below) in order to keep empty totes on the rack, according to the replenishment ‘Two-bin’ system that I am trying to model. In fact, I want just to insure that you have already included this two conditions in this model (because I couldn’t see them in the code, but when I run the model below they are taken into consideration):

• 1- totes of type 1 (tote1) are placed in the front of the rack (in the side of the conveyor).
• 2- the operator picks items from tote1 first and the rest is picked from tote2.

Thank you again for your help.

Hi @Matthew Gillespie would you please reply to the above question, I really need your answer to continue working on this model. Thank you.
