Part III focuses on food process industries that combine batch and continuous operation modes in their overall production plant. In Chap. 5, a mixed integer programming framework and a solution strategy are presented for the optimal production scheduling of multiproduct multistage semicontinuous process industries. An ice-cream production facility (UNILEVER, the Netherlands) is studied in detail. The overall mathematical framework relies on an efficient modeling approach of: the sequencing decisions, the integrated modeling of all production stages and the inclusion of strong valid integer cuts in the formulation. The simultaneous optimization of all processing stages increases the plant production capacity, reduces the production cost for final products, and facilitates the interaction among the different departments of the production facility. The proposed mathematical formulation is well-suited to the ice-cream production facility considered; however, it could be also used, with minor modifications, in scheduling problems arising in other semicontinuous industries with similar processing features.
