X_{ijv :} no values?????????

Y_ijvk : no values??????

below the model attachement

Best regards 

Hi,

your model is not feasible. When I run it in the IDE I get a relaxed solution.

If I run it with oplrun, I get no solution.

hi, please i have a problem ,

i want to say : forall(i in I, j in J, v in V:j!=i) 

      (Xijv[i][j][v] ==1) ==> (F[i][v] + item (TIJ,<i.i,j.j>).temp <= F[j][v])

in cplex : 

 forall (i in I, j in J, v in V:j!=i)  

if  ( Xijv ==1)  then  F[i][v] + item (TIJ,<i.i,j.j>).temp <= F[j][v]; //   Xijv is a decision variable

errors : the if-then loop can not contain a variable decision, 

so what can i do??

Best regards 

Hi,

you should rewrite

 ( Xijv ==1)  then  F[i][v] + item (TIJ,<i.i,j.j>).temp <= F[j][v];

into something like

 ( Xijv ==1)  =>  (F[i][v] + item (TIJ,<i.i,j.j>).temp <= F[j][v]);

regards
