Looping command in Flexsim

In my model i have a global table having 3 rows and 1 columns. when i use a "for" loop as given below, the model gives the output for only first row of table, but what is need is the loop has to continue for all three rows and produce the output. provide some light on this..


int row;
for(row = 1;row <= gettablerows("sample"); row++)

{
int x=(gettablenum("sample",row,1));
return x;
}

Hi,

The loop will stop when it reach return in your case it will be already on the first row.

Hi Lars,
How to continue the loop to further rows. Instead of return what should be used to get the output for each row.

Hi,

Everything depends what you want to do with the value from the loop. If you want to print the value to e console use pf or pd.

Try to explain what you try to do, it will be easier to guide you.

Hi Lars,

Consider flow items are placed on the racks with certain label value. In order to retrieve them from racks based on the label value i used the global table. Each row in global table will have label of flow items to be retrieved. Hence i need flow items to reach down the rack for every row increment.

Hi,

If I understand right.

I would have the logic for reaching the item in the rack inside the loop.

Hi,

One question.

Where do you have the for loop? On what trigger?

Lars-Olof

Using the loop in pull requirement of queue.

Hi,

If I remember right pull will only work for one item, it can not pull many items at the same time.

Back to what are you trying to do? Explain what you try to do and if you can include a small demo model also.
It will be much easier to guide you if you explain what you try to do.

I have attached the model for your reference. Based on the global table input the flow items from the rack has to be brought down to the queue.

Hello Manoj,

not necessary: in the rack activate under send to reevaluate sendto on Downstream Availability.
As Lars-Olof has mentioned the return command stops the loop. Therefore write an if-statement in the pull requirement of your queue

if( x && Y) return 1;
