5 DyOS: Dynamic Optimization Software What is dynamic optimization? Start Drive 250 m in minimal time! Start with v = 0, stop exactly at x = 250m! Maximal speed is v = 10 m/s! Maximal acceleration is a = 1 m/s²! Finish v( t) v max x( 0), v(0) = 0 MAX Acceleration a Time [sec] 5 HP on Windows enter MIN v( t f ) = 0, x( t f ) xt. f Speed v Distance x Time [sec] omputing and ommunication

6 DyOS: Dynamic Optimization Software Dynamic optimization in chemical industry Plastic A omposition of A und B => unfeasible material Plastic B Task: hanging the product specification (from A to B) of a plastic manufactory in ongoing business! Minimize the junk (composition of A and B)! Search economic and ecologic otimal operational mode! This task is solved by the DyOS (Dynamic Optimization Software) tool, developed at the chair process systems engineering (LPT: Lehrstuhl für Prozesstechnik) at RWTH Aachen University. ontact: Arndt Hartwich ( ): 6 HP on Windows enter hartwich@lpt.rwth-aachen.de omputing and ommunication

Search economic and ecologic otimal operational mode!

7 DyOS: Dynamic Software Optimization One simulation typically takes up to ten days and requires a significant amount of memory: Not suited desktop machines Parallelization necessary to speed up simulation process hallenges: DyOS requires commercial software packages (source available) DyOS is bound to Windows because of gproms modelling tool gproms is bound to Visual Studio 6 Solutions: Separate the gproms Interface from the rest of the software and source it out into a DLL Port the rest of the software to the new compiler: V 8, Intel HP on Windows enter omputing and ommunication

8 DyOS: Dynamic Software Optimization state integration requires 1 jacobian per step (1 Jacobian: 0.2 sec) sensitivity integration requires >>1 jacobians per step sensitivitiy equation systems i are independent of each other computational time of LUdecomposition small Dissertation: Martin Schlegel Numerical state and sensitivity integration ms the greatest part of computational eft (>99%) 30-40% of computational times required computation of jacobians (~ jacobians per sensitivity integration), the remaining part mostly depends of number of sensitivities Idea: Separation into different tasks (subprograms): 1. Integration of states 2. omputation of Jacobian matrix 3. Integration of only a part of the sensitivity equation system on different PUs 8 HP on Windows enter omputing and ommunication

Numerical state and sensitivity integration ms the greatest part of computational eft (>99%) 30-40% of computational times required computation of jacobians (~10.
