Optimal scheduling of cement mills operations increases
the revenues of the cement producer by reducing the energy
bill and the amount of low grade cement produced. Manag
ing the conveyor belts system allows to prioritize the filling
of certain silos and to fulfill the transportation constraints,
with a decrease of electricity and transportation costs. In
this article an approach to production scheduling based on
hybrid systems in the Mixed Logical Dynamical models
formulation and a description of the rescheduling problem
in a model predictive control framework are presented. The
conveyor belts and silos management is formulated as a
Mixed Integer Linear Problem.
