The paper studies the problems of developing fuzzy and linguistic models of poorly formalized production facilities using available fuzzy information and other types of data. Since known methods do not allow us to effectively solve these problems in a fuzzy environment, we propose a systematic method and a heuristic approach to decision making for the effective objects control in a fuzzy environment. The proposed system method makes it possible to develop fuzzy, linguistic models of complex objects, and a heuristic approach to the formulation and solution of the adoption problem - to adequately and effectively solve the problem of fuzzy described objects control. In the proposed heuristic method of fuzzy decision making, effective control of the coking process is ensured through the maximum and effective use of fuzzy information representing the experience, knowledge and intuition of the decision maker, experts. Using the proposed system method, fuzzy and linguistic models of the studied coking reactors of the delayed coking unit of the Atyrau refinery were developed. A computer modeling system has been created that allows, as a result of modeling, to select the optimal operating modes of coking reactors. Based on the developed models using the proposed heuristic decision-making method, modifying and combining the principles of maximin and Pareto optimality, the problem of effective control of the delayed coking process was successfully solved. Comparison of the obtained results with the results of known methods and real data shows the advantages, efficiency and high adequacy of the proposed methods in a fuzzy environment. The practical significance of the results obtained is that they can be adapted and successfully applied in modeling and decision making for the effective complex objects control in a fuzzy environment.

Technological development of furnaces over conventional melting methods of diesel or gas‐fired furnaces is necessary. These furnaces have large amount of heat losses and hence their thermal efficiency is very low. Moreover, these furnaces do not produce good quality melt because of the chances of embedment of impurities from after‐combustion gases and agitation. The time required for melting in such furnaces is more. Also, insulation is not provided and there are heat losses which increase the time of melting. An electric resistance heating furnace is developed which overcomes all the problems associated with the fuel‐fired conventional furnace. The thermal efficiency of this developed furnace is found to increase quite drastically up to 85%, which is by about 33% more than conventional furnace; while reducing the operating cost of furnace. This benefits industry overall by profit of 70% and certainly can replace the existing conventional fuel‐fired furnaces.

The purpose of the foundry is to provide the consumer with blanks for general machine-building (special) purposes which are as close as possible to the size of the future part in full compliance with the requirements. The competitiveness of these products is primarily dependent on the use of efficient and reliable smelting equipment which meets the necessary cost. The replacement of high-value ironworks and ironworks iron with steel scrap using induction melting furnaces (ICFs) reduces the cost of producing synthetic cast iron. However, this results in temperatures greater than 1500 °C, reduced lining stability and increased downtime of the smelter. As a result of the research carried out, a technology for the use of quartzite is proposed. Thereby, the purpose of this work is to establish temperature regimes for the smelting of synthetic pig iron, allowing the use in metal filling up to 70–90% of steel scrap; this leads to a reduction in the cost of purchasing bulk materials (depending on the brand of cast iron) up to 50% and, thus, increases the efficiency of synthetic cast iron smelting and castings production in general. After removal of the original moisture and the subsequent sintering of the manufactured lining, it provides the possibility of melting using the melting temperatures 1550–1600 °C. It increases the efficiency of the operation of the melting furnaces and eliminates the consumption of the ironworks and the melting of the cast iron in the blast furnace, as well as the cost of the lost alloy. As a result, metallurgical production will be able to reduce the volume of production and supply of cast iron for ironworks, which will improve their environmental situation during the production and processing of necessary raw materials.
