The structure and mathematical models of the information system "Аluminum melt Mixer"
Incoming article date: 07.04.2019An important aspect in the creation of information and training systems for training and advanced training of technological personnel of industrial enterprises is the development and implementation of mathematical models of the studied technological processes at the stage of forming algorithmic and software of such systems. The considered information and training system is associated with the blending and casting of aluminum alloys of various grades. The system contains the necessary amount of theoretical information that describes the basic principles of aluminum production using the most well-known technological operations aimed at the formation of the required metal alloys with a given chemical composition. The information-training system is based on a mathematical model of the technological process, in the development and description of which both the principles of informational similarity and the physicochemical laws are used using experimental-statistical modeling methods. The structure of the information and training system consists of structural units that interact logically with each other, which allow the formation and solving of various technological problems of melting aluminum melting in smelting furnaces. Each unit has a certain meaning and performs the required amount of load. The system consists of seven important and weighty structural units. The interactions of the studied production object with the control actions and external disturbances make it possible to form the initial parameters of the task, which in turn become the basis for user interaction with the training system. The user interface of the system allows visualizing the aspects of technological change that are taking place and storing the student’s corrective actions for further analysis in the computer’s memory. If necessary, the system can provide the user with the opportunity to use the potential of an interactive assistant, in the event that he is difficult or unable to determine the weight of the next corrective adjustment. The interactive assistant based on the current parameters of the technological problem is able to determine and suggest to the user the use of the most optimal control action for the best solution of the problem. Thus, when introducing these principles of training, the system should show its effectiveness by reducing the final cost of the finished metal products, by reducing errors in technological operations and empirical calculations of the masses of the components used, increasing its consumer qualities.
