Hi all,

Could you please help me with this model? I get an error message for one of the constraints and don't know how to solve it.

Thanks in advance.

Hi,

for cons3 can you try to protect out of bounds for Time with

forall(k in Freight, j in DCities, m in Mode, t in Periods )
    cons3:
      sum(i in CCities:
      (intValue(i) in 1..nbMode)  &&
      (t-Time[intValue(i)][intValue(j)][intValue(m)] in Periods) )
        (x[i][j][k][m][t-Time[intValue(i)][intValue(j)][intValue(m)]]) ==Demand[intValue(k)][intValue(j)][t]-  e [k][j][t];

Regards
