Abstract
The article considers methods of modeling in multi-criteria conditions for optimization of management of the installation of catalytic cracking. Ways of increase of efficiency of technological complexes of deep oil processing by making decisions on the basis of mathematical modeling have been given. Mathematical formulations of the problem of optimization of technological systems on the example of optimization of operating modes of the catalytic cracking installation on the basis of the methods of the theory of fuzzy sets and expert assessment have been formed and their solutions have been developed. On the basis of the collected qualitative information and research results, a mathematical model of the reactor was created and on the basis of the created model, management tasks were formed to choose an effective mode of operation of the technological system. Based on the obtained expert information, database rules describing the operation of the input parameters of the reactor reactor catalytic cracking unit have been created.
