Hello,

I have these tuples in my model and I want to generate random variables near the base station for my terminals (base station is the first item in the tuple infratuple. The other are femtocells.) in a script block.

tuple terminaltuple{
key string name;
int x;
int y;
float maxBW;
{float} availBW;
}
{terminaltuple} terminal=...;
terminaltuple dummy;

tuple infratuple{
key string name;
int x;
int y;
{float} PL;
float maxPower;
float cap;
}
{infratuple} infra=...;

The script block I have is this:

execute{
writeln(terminal);
for(var t in terminal){
dummy.x=100000;
dummy.y=100000;
while((infra(1).x-dummy.x)^2 + (infra(1).y-dummy.y)^2 >= 500.0){
dummy.x=875+Opl.rand(30);
dummy.y=268+Opl.rand(30);
//writeln("testing- xter="+dummy.xter + ";yter="+dummy.yter);
}
t.x=dummy.x;
t.y=dummy.y;
writeln("success adding "t.name" "t.x" "+t.y);
}
}

This script don't work. Can you help me?
Here is the data file:

In the while() I want to access the field int x (885) and the field int y (278) of my first element (<", 885, 278, {1.0}, 60.0, 3700.0>,) of my set infra!

Can you help my with the declaration?

You should probably ask this question on the OPL Forum.
Also wrap your code into '{code}' tags. This way it is easier to read and not scrambled by the Forum software.

I found the solution. I inserted to the model these type of arrays to access my tuple element:
terminaltuple terminalterminals = t in terminaldata ;
infratuple infrainfrastructure = i in infradata ;

Also I had to add 2 string sets for the infrastructure and the terminals:
{string} infrastructure=...;
{string} terminals=...;

And in the while I wrote:
while((infra.x-dummy.x)^2 + (infra.y-dummy.y)^2 >= 500.0){
