Description

 Research methods – system analysis and computer modeling of technological processes and information technologies. The work presents the current state of development of computer forecasting systems; the task of creating a system for predicting the thermal regime of metallurgical equipment with increasing the speed of the computing algorithm was set; the modeled system and the software application are described; the work of the received program was analyzed. The present state of the problem of improving the accuracy of computer simulation results is presented. The applied algorithm and methods of conducting numerical experiments regarding the improvement of computer models by increasing the accuracy of calculations are described; the results of computational experiments were analyzed and systematized. The use of economic difference schemes and parallel calculations in solving the problems of heating and melting of materials allows to significantly reduce the computational costs for solving the difference analogs of ordinary differential equations and partial differential equations. The results of computational experiments allow establishing rational modes of introduction of additives that provide the most favorable conditions for their melting. An analysis of the latest research and publications in the field of fuzzy and neural network modeling in control systems is presented; the question of construction and adjustment of a fuzzy adaptive PID controller, consisting of a block of fuzzy adaptation of fuzzy coefficients of a linear PID controller, as well as a neurocontroller with a forecast, is considered. To develop an information system for constructing a fault tree for assessing the reliability of technological systems, the concept of risk and methods of reliability assessment, features of constructing a fault tree are described; the event tree event probabilities are calculated.
