Dear all,

I stuck in a problem:

At the beginning, I have defined 2 tuple types and initialized 2 sets respectively.

[b]tuple ship{
int id;
int bay;
}[/b]

and

[b]tuple job{
int qc;
ship ves;
}[/b]

[b]{ship} Ships=...;
{job} Jobs=...;[/b]

One of my decision variables is:

[b]dvar int+ x[Jobs] in 0..1;[/b]

Without the postprocess part, my model works well. In order to interpret the final result more easily, I add the postprocess part at the end of the model. The following is my postprocess:

[b]tuple result{
   int qc;
   int bay;
}
{result} Results[Ships];

execute{
var k;
for(k in Jobs)
      if(x[k]==1)
   [b][color=red]   Results[k.ves]=<k.qc, k.ves.bay>;[/color][/b]
}; [/b]

However, ILOG provides me the runtime error for the line in RED above:

[color=red]error: Scripting compiler error: missing expression. [/color]

I have tried my best to fix it but still can not figure it out :(.

Seek your great help! Thanks a lot!

Try
      Results[k.ves].add(k.qc, k.ves.bay);
instead.

Scripting syntax does not support modelling syntax for tuples <,>.

Thanks.
I try your method. However, this time it reports that : [color=red]undefined method 'add'[/color]. Do I miss something?

How is Results declared?

This snippet works for me:
tuple T {
    int i;
    int j;
}

range R = 1..10;
{T} A[R];

execute {
    for(var i in R) {
          A[i].add(i,i);
    }
    writeln(A);
}

I have run your code.

[b]tuple T {
    int i;
    int j;
}

range R = 1..10;
{T} A[R];

execute {
    for(var i in R) {
     [color=red] A[ i ].add(i,i);[/color]
    }
    writeln(A);
}[/b]

[color=red]Scripting runtime error: undefined method 'add'.[/color]

My Ilog is version 5.0.

It works with 6.0.1.
