Hello, i wantt to limit the value of the objective function between the lower and the upper bound (LB,UB). How can i do that ? 

(LB, UB) = (24, 32).

minimize staticLex(max(i in Jobs, o in Ops: o.pos==jlast[i]) endOf(ops[o]) in 24..32,-sum(i in Jobs,j in Oper, k in Mchs) s[i][j][k]); // Doesn't work.

staticLex() is specific to CP optimizer. So you should ask this question in one of the CP optimizer forums here.
