A dynamic simulation model of a 3-ply paperboard production process was developed. The simulation model consists of stock preparation and proportioning, short circulations, wire and press sections, and 75 drying cylinders including the steam and condensate system. Functionality of the automatic grade change program used on the machine was modeled as well. Physical, first principles models were used whenever possible. Simulator was extensively validated using historical data. The simulator has…

Coupling dynamic simulation and interactive multiobjective optimization for complex problems: An APROS-NIMBUS case study
TLDR
This paper considers APROS, a dynamic process simulator and couple it with IND-NIMBUS, an interactive multiobjective optimization software and proposes an augmented interactive multiObjective optimization algorithm, which will help solve a dynamic optimization problem in a two-stage separation process.
