Abstract

The paper proposes a new approach to designing of a structured mathematical model for chemical-technological systems (further - CTS) of refinery in uncertainty. These uncertainties are depending from randomness and a fuzziness of the input data for a various types of information. Idea and novelty of the proposed method lies in the fact that at first the results of studies of each CTS unit based on the gathered information and the adopted criteria for evaluating the model of separate element is constructed. Then to simulate the whole process the developed models are combined into a single system. The designed method has been successfully implemented during the design of models of units of catalytic reforming at Atyrau oil refinery. Analyses and comparison of the known results and simulation results of the proposed method, and the experimental data from Atyrau refinery have shown the effectiveness and advantage of proposed modeling approach to interrelated technological units complex.
