I have done the whole program in CP but I would like to test it in CPLEX to see if it goes faster. Any idea why CPLEX is giving error on this constraint (
La función operator<(int,int) no está disponible en el contexto CPLEX.  
)?

range TiposDeTurnos=1..NumTurno

     forall (i in Ctas, tu in TiposDeTurnos: tu>1)
           forall (t in InstantesDelTurno)
                 (DosCtasOcupanUnSector[i][t] == 1 && HorarioCta[i]==tu) => (t >= TiposDeTurnosInstInicial[tu] && t<TiposDeTurnosInstInicial[tu]+TiposDeTurnosDuracion[tu]);

Hi

strict inequality is not allowed any more within a constraint with CPLEX so you could change

t<TiposDeTurnosInstInicial[tu]+TiposDeTurnosDuracion[tu]

into

t+epsilon<=TiposDeTurnosInstInicial[tu]+TiposDeTurnosDuracion[tu]

with epsilon a very tiny value
