Process Integration and Design Optimization technologies for modelling improvement

This paper aims to present a methodology that helps improving systems modelling by using Process Integration and Design Optimization technologies. Then, the methodology has been applied on an automotive case study: the improvement of the hybrid vehicle TOYOTA PRIUS III modelling. This work has been carried out in the context of the international research program PLACIS (PLAteforme Collaborative d'Ingenierie Systeme). It is the result of the collaboration between Institut Polytechnique Grand Paris and Esslingen University. The experimental data needed for the study were measured on a test bench and a detailed model developed in DYMOLA-MODELICA environment of the vehicle powertrain was given by the company Bosch. Thereby, in order to develop and validate the model, an optimization tool was used to identify the unknown parameters of the system and integrate the energy data management into the simulation.
