NOVEL FRAMEWORK FOR SHORT-TERM AND MEDIUM-TERM SCHEDULING OF LARGE-SCALE INDUSTRIAL CONTINUOUS PLANTS

摘要：

In this study, we describe a novel approach for the short-term and medium-term scheduling of large-scale industrial continuous plants. Two sub-problems are solved for medium-term scheduling using a rolling-horizon based disintegration method. An upper-level model is used to find the optimal number of products, and the length of the time horizon to be considered for solving the lower level short-term scheduling problem. At the lower level, an improved model is presented for short-term scheduling of continuous processes using unit-specific event-based continuous-time representation. The proposed formulation is demonstrated on a large-scale industrial case study resulting in effective utilization of the main units.
