Published: December 2020

Abstract
Within the conditions of increasing open pit mining, an urgent problem is improving the efficiency of mining excavators. The variety of parameters, properties and characteristics that determine the quality of functioning, poses the problem of using fuzzy methods to evaluate them. Due to the fact that the loads arising in the working equipment of mining excavators are determined by a large number of different factors that are difficult to imagine by analytical formulas, i.e. these factors are mostly random, it is necessary to implement models using non-standard approaches. In this study, we used the methodology of the theory of fuzzy logic and fuzzy sets, which allows overcoming the difficulties associated with the incompleteness and vagueness of the data in assessing the prediction of the forces arising in the working equipment of mining excavators, as well as with the qualitative nature of these data.

Authors: Sharipov M I 
Published: December 2020

Abstract
For a long time there has been a tendency to increase field productivity, therefore, increasing oil recovery is the main task for fuel and energy complex. Currently, neural networks are increasingly used in various industries. The advantage of neural networks is to work with a large amount of data, however, it must have sufficient data sets collected and prepared for its operation, thereby achieving high decision accuracy. When developing oil and gas fields, the main task is to ensure maximum production from an economic and physical point of view. Oil production at oil and gas fields varies in volume, complexity, operating conditions, etc., therefore, it is necessary to find the optimal production conditions for each field. At the moment, the main problems in oil production at oil and gas fields are: the long processing time of data collected from wells, the increased risks of operating these wells, as well as the low amount of oil produced. The main objective of this study is to develop a control method us in artificial intelligence to control the production process in oil and gas fields, taking in to account all factors, in order to maximize oil production. In the course of this study, direct transmission to the neural network was obtained, which allows oil to be extracted at oil and gas fields, taking into account all factors. The resulting neural network, without reconfiguring weighted connections, generates output signals when applied to the input to the network. The resulting neural network expresses the patterns that are present in the input data. This network turns out to be the functional equivalent of some model of dependencies between variables.

Published: December 2020

Abstract
Currently, quality management issues of modern automated production facilities are becoming increasingly relevant in connection with development and implementation of innovative metrological systems used in production quality management systems. The problem of making decisions on conformity of products to the established requirements, taking into account measurement uncertainty, is essentially one of the determining problems of quality assurance, since in order to avoid incorrect decisions when accepting products, it is necessary to be able to evaluate (calculate) the size of the measurement uncertainty area. The article provides an improved procedure for calculating uncertainty, which helps to avoid making such decisions.

Simulation of the steelmaking process using collision avoiding cranes moving models
Authors: Antonova Anna , Aksyonov Konstantin 
Published: December 2020

Abstract
The paper discusses a steelmaking process and its optimisation using simulation. The optimisation goal is to reduce the total distance travelled by cranes in all spans as well as to reduce the steel waiting time before casting on a continuous casting machine. Models of the process under study have been developed in the AnyLogic simulation software and the modelling subsystem of the metallurgical enterprise automated system. A comparative analysis of the simulation results has been conducted. All results are feasible in terms of meeting the technological constraint on the steel downtime in front of the continuous casting machine for no more than 15 minutes. When comparing two collision avoiding cranes moving models, a choice has been made in favour of a model that provides cranes movement to the nearest steel processing aggregate. Using this model allows to reduce the total path travelled by cranes by 6%. The results of using different modelling systems are consistent.
Simulation of adaptive drill machines with hydraulic drive
Authors: Lemeshko M A , Zibrov V A , Bashnyak S E 
Published: December 2020

Abstract
In a number of technological machines, the drive performs two related working movements. As you know, most of the machines used for Metalworking, also have a drive with one or two engines, which provides a working process with two movements of the cutting tool relative to the workpiece or part. As a rule, this is rotational and translational motion. The ratio of the speeds of these movements, or the ratio of the two movements, determines the modes and indicators of the cutting process. This ratio is often optimal. The article deals with the method of modeling the adaptive drilling machine, as an example of studying and analyzing the automatic process of maintaining rational cutting conditions with two related working movements. In this case, the feed force can be greater than the nominal value within the power and strength limitations, or be negative, providing reverse movement of the drill in case of jamming. What is new is that the simulation of the adaptive machine operation process is performed, showing the features of the adaptation process, self-adjustment of the drive to rational cutting conditions, with a change in the strength of the drilled material. In particular, it is possible to configure the adaptive scheme to the required degree of adaptation. Equations and the developed method of the analysis of the adaptive drive executed on the basis of two differentials are given.
