FN ISI Export Format VR 1.0 PT J TI Simultaneous optimization of planning and scheduling in an oil refinery AF Zondervan, Edwin van Boekel, Tijn P.J. Fransoo, Jan C. Haan, Aandré B. de AU Zondervan, E van Boekel, Tijn P.J. Fransoo, JC Haan, Aandré B. de BP 925 EP 929 AB In earlier work we have developed and tested a scheduling model [1] in the AIMMS software. In this follow-up contribution we will develop a planning model. Next we will identify the information flow between scheduling model and the planning model. Lastly we will integrate the two models in a straight-forward fashion using run-modes and rolling-horizon methodology. With a case study we prove that the overall strategy aids systematic integration of the two levels, which allows fast optimization of the short-term as well as the long-term decisions without significantly affecting the quality of the solution.
