Abstract
Abstract
This paper presents a Constraint Programming model to supportthe logistics of the Brazilian Book and Teaching Material Program(PNLD). The proposal explores in an integrated manner two globalconstraints to concisely express the grouping of orders on palletsand the scheduling of production. The experimental results, conducted on the MiniZinc platform with the OR-Tools CP-SAT optimizer,on 34 artificially generated instances, validate the proposed modeland indicate that the approach is effective for small-sized instances.
