hi,

i have this problem, an error that i can found why :

tuple Sindnoeud{
 
    int i;
}
   tuple Sindnoeud2{
     int j;
   }     
  tuple Sinddepot{
 
    int i;

dvar int+ Yijvk[I][J][V][K ]in 0..1;
dvar int+ U[V] in 0..1;
dvar int+ Xijv[I][J][V] in 0..1;
dvar int+ F[I][V];
dvar int+ D[V];
dvar int r[I];
dvar int TSHikv[I][K][V];

here i want to find r [i] is equal to the distance between the node i and the start point (dépôt = ID ) so i have an error in this constraint

c222(i in I, j in ID, i!=j)
 r[i] == item(DIJ,<i.i,j.j>).valeur;

 i have 2 error in this constraint :

1 : syntax error, unexpected (identifier)

2 : impossible de charger le modèle

thanks

One obvious error is that you did not close the bracket after defining "Sinddepot"
