I'm executing the optimizer taking into account makespan costs but the optimization result never show a good makespan, because there are a lot of GAPs between orders. I mean, the optimizer avoids to move planned orders very earlier in reference to the sales order requierement.
In the other hand, all the delayed planned orders are scheduled toghether without gaps.
The fact is that we are using a MTO strategy and i don't know if could be any parameter that constraints this issue.
We are not using expiration dates.
Thanks in advance.
