An important production programming problem arises in paper industries coupling multiple machine scheduling with cutting stocks. Concerning machine scheduling: how can the production of the quantity of large rolls of paper of different types be determined. These rolls are cut to meet demand of items. Scheduling that minimizes setups and production costs may(More)
We consider an agricultural production problem, in which one must supply a given demand of crops while respecting ecologically-based production constraints.
