maximum item per cell in rack

Hi, dear all

I have a problem about maximum item per cell in rack.

When I run my model I find some cells of rack with two item, but I just want per cell maximum item =1.

I know the placing logic in rack, I can do it if I choose the "Random Bay if Available".

But I have my own logic so I choose the "By Expression".

Please help me to check and help me to solve my problem.

Thanks.

following is my model

20200619_harmony algorithm assignment.fsm

Software Version:

FlexSim 19.0.9

rack flexsim 19.0.9 maximum item per cell in rack

Hi @JUN-WEI P,

There isn't an easy way to do this in version 19.0, but version 19.2 has some nice Querying features that would be perfect for what you are trying to do.

If you want to stay with 19.0, they you will need to complete a manual check before you assign your items to slots. You can use the following syntax to check a cell content:

Model.find("Rack3>variables/contenttable").as(Table)[<insert Bay Num>][<Insert Level Num>]

Whenever you assign "item.toBay" and "item.toColumn", you will want to run a check to make sure it is empty:

int content = Model.find("Rack3>variables/contenttable").as(Table)[<insert Bay Num>][<Insert Level Num>];

if (content == 1) {<increment to next level>}

@Benjamin W2 Sorry, Can you use my model to demonstrate for me and do not use the process flow? In every cell of different rack, I have already assign specific cell depending on item.type from global table "base1" to "base8".And if I do that, what should I write in <increment to next level> ?

P.S. If I write the code in "place in bay", should I still write the conditional decision in "place in level"?

if (content == 1) {<increment to next level>}

Please tell me, thank you!!
