Georg Schopfer, Lars v.Wedel, Wolfgang Marquardt:
An environment architecture to support modeling and simulation in the process design lifecycle
AIChE Annual Meeting 2000, Los Angeles, 12-17.11.2000
Models about chemical processes and plants contain valuable knowledge about the companies assets because they allow some experiments to be made with the plant or process without actually modifying or building it. Considering the importance of models and the costly efforts needed for their development, it must be considered a waste of ressources that (in general) models are neither reused for the development of new models and often not even used for simulation studies later on in the plant's development lifecycle. This is mainly caused by (i) insufficient means to distribute, maintain, and communicate models within the process design team, and (ii) a lack of integration among process simulation tools that would enable the combined use of existing models for a simulation independent of the tool they have been developed with. This contribution proposes a model repository that maintains mathematical models in a structured manner and provides central access to them for all model developers and users. A heterogeneous simulation platform is presented which can execute simulation experiments involving otherwise incompatible tools. Results are presented along the development of a Nylon production process as a case study.
