Suppose I have a set at time t = 1, Damage = {1,5,6,9,11,21,23,29}. The element of this set gets updated at different periods depending on the decision variable repair[n][t]. So to update the element of the set I am writing the Code in OPL Cplex that is given below. But I am not getting results with this code. Please guide me so that I can find out the decision variable dependent time varying set

{int} Damage[time]; 

// objective function
max sum(n in bus)(t in time)pd[n][t];
// Constraints

subjected to {

forall ( t in time, rc in repair_crew, n in DamagedLines){
    (StatusLine[rc][n][t] == 1) => (repair[n][s]==1);
    (StatusLine[rc][n][t] == 0) => (repair[n][s]==0);
  }
}  

forall (l in Damage, t in time:!(t==1)){
    (repair[n][t]==1)  => Damage[s].remove(l);   
  }
} 
}
