This paper presets a modern approach to the modelling of multi-dimensional industrial processes. A proposed methodology is focused on processes working in more or less complex technology environment and integrates different approaches for simulation of components of the investigated systems. It is realized in form of the elastic programmable software package. This kind of approach includes an application of mathematical models (derived from physical relations, parametric or others) implemented in a relevant software, that allows us to prepare simulations so as to explore process behaviours in many situations, especially critical ones. The key issue of this type of approach is to prepare a model that would approximate a process dynamics with a satisfactory quality. Therefore, in this paper the problem of fitting physical models described by a set of ordinary differential equations is considered. This type of models have a set of unknown parameters that have to be estimated so as a model could properly mimic and predict the process. A tool for optimizing models prepared in the PExSim is described and its capabilities are presented. At last, an application of the PExSim in modelling of industrial processes and models optimization is presented with the help of an example of a waste water treatment process. Furthermore, some procedures of the complex models optimization are proposed. As the final result of an optimization a waste water treatment process model is achieved. Example results for selected concentrations of contamination in treated sludge are presented.
W artykule przedstawiono nowoczesne podejście do modelowania wielowymiarowych procesów przemysłowych oraz metod optymalizacji utworzonych modeli. W treści opisano narzędzia umożliwiające modelowanie oraz optymalizację wraz z przykładem ich zastosowania. Istotą prezentowanego podejścia jest możliwość elastycznego dostosowywania utworzonych pakietów programowych do potrzeb użytkownika. - Źródło:
