Resumen:
This contribution presents a new Constraint Programming (CP) formulation to address the optimal operation of multiproduct continuous processes. In particular, facilities having continuous stages, which manufacture intermediate or final products and a limited number of intermediate stor-age tanks, are tackled. The problem involves finding (i) the optimal sequence of production runs and (ii) the optimal agenda of usage of each storage tank. The proposed formulation is able to handle different features found in industrial environments such as dissimilar machines, sequence-dependent change-over times, forbidden campaign-machine assign-ments, production runs´ length constraints, etc. Moreover, one of the main contributions of this pa-per is the handling of constrained resources of vari-ous types, such as intermediate storage tanks of lim-ited capacity and qualified manpower required at some stages.
