Abstract:

The scheduling optimization problem of refinery processes was studied in view of the production characteristics such as stability and chronicity whose definitions are given first. Based on the  given definitions, production characteristics were described using disjunctive normal form and logic proposition. To evaluate production characteristics quantitatively, the performance criterion of stability and chronicity were proposed. Finally, based on expressions of production characteristics, a generalized disjunctive programming scheduling optimization model was set up. Simulation results obtained from the scheduling of a certain refinery having  expressions of production characteristics whether or not show that the scheme of the production characteristics based scheduling model can improve the performance of production characteristics and is  feasible and practical.

Key words: refinery processes, production characteristics, production scheduling, generalized disjunctive programming, optimization
