Hello,

In my model I have these data:

{string} terminals=...;

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

terminaltuple terminalterminals = t.name : t | t in terminaldata ;

Also I have this dvar:
dvar int bi in terminals;

How can I express that forall the terminals their bandwidths b[i] must belong in the set of their availBW?

Also in the constraint block I have these:

forall(i in terminals)
b[i] <= terminal[i].maxBW;

forall(i in terminals)
b[i] == 64 || b[i] == 128 || b[i] == 256 || b[i] == 384 || b[i] == 512 || b[i] ==1024;

Can you help me? I am a bit confused!

You may have better luck if you repost this in the OPL forum. Also, surrounding your code with {code} before and after will help readability.

I found an acceptable solution.
In the tuple terminaltuple I changed the last field {float} availBW with 3 new fields of integers (availBW1, availBW2, availBW3) and in the subject to block I add:

forall(i in terminals)
b[i] == terminal[i].availBW1 || b[i] == terminal[i].availBW2 || b[i] == terminal[i].availBW3;
