We present an approach to online scheduling of chemical plant operations that incorporates precise knowledge of the dynamics enforced by the automation system. The scheduling problem is solved using a discrete-time state-space resource task network formulation. Rescheduling is triggered when the schedule currently being executed conflicts with the dynamical behavior allowed by the automation system. We present a case study to show that better operation is achieved using our approach compared to iterative rescheduling alone.
