Resumen:
This work presents a multiperiod optimization model for multiproduct batch plants
operating during several time periods with different characteristics because of seasonal
and market fluctuations. This model simultaneously considers decisions about the
design, operation, scheduling, and planning of the plant and the corresponding tradeoffs
among them. Thus, decomposition mechanisms, which have been frequently used
in previous approaches, are avoided through a formulation that takes into account the
main elements of these problems. Besides, decisions are affected by different context
conditions arisen by the multiperiod effect. Through a mixed integer nonlinear program,
different alternatives of mixed production campaign are considered, handled by
means of a novel set of scheduling constraints. This approach is posed for a fermentors
network with high detail level in the description of the unit operations in a plant
that produces yeast and ethanol.
