A multiperiod optimization model for the simultaneous planning and scheduling of multiproduct batch plants is presented in this work. Decisions about production and storage of different products, as well as production campaign in each period are jointly taken into account. Thus, for each time period, the number and size of batches of each product in the campaign, the assignment of batches to units and their sequencing, and the number of repetitions of the campaign must be determined. Different trade-offs among the various decision variables are evaluated according to seasonal and market fluctuations presented in each period. The proposed modelling framework provides a valuable tool for guiding the decisions in planning and scheduling of multiproduct batch plants.
