DECISION SUPPORT SUPPORT SYSTEM FOR MANAGING THE RATIONAL REGIME OF ORE YARD WORKING UNDER CONDITIONS OF AVERAGE OF RAW MATERIALS

Abstract

The processes of charge preparation of metallurgical raw materials for agglomeration and redistribution refer to processes that are characterized by the complexity of measuring the main technological parameters, their uncertainty, the presence of mutually influencing internal connections, transport delays for control actions, therefore, the development of control systems for such processes presupposes the presence of mathematical models for forecasting and calculating for warning. The paper considers the issue of creating a decision support system for managing the process of averaging bulk materials at the ore yard of a metallurgical enterprise in order to ensure a stable chemical composition of raw materials. Using mathematical models based on the balance method and the theory of fuzzy logic, each stage of the raw material handling processes is described, its chemical composition is predicted in the fields of the receiving trench, in the volume of the loading grab, the ridge and the stack layer, and recommendations for unloading batches of materials are calculated, which come to the enterprise from mining and processing plants.
