The essential quality parameter of rolled products is the flatness along the rolled stock length. The profile defects of the rolled stock, produced at the modern plate mill 5000, frequently occur in the course of intense cooling implied by the thermomechanical rolling technology. To eliminate them, the mill lines include cold straightening machines. The authors show typical flatness defects caused by the occurrence of longitudinal, central and edge waves. Further, the paper characterizes a cold straightening machine installed at the mill 5000 and provides the parameters of electric engines of straightening rollers. The key drawback of the design algorithm for electric drives’ control is setting engine constant moments regardless of the thickness and character of the defects in the rolled stock processed. This causes overloading of the electric and mechanical systems of certain rollers and unsatisfactory product quality. To eliminate the drawback, the authors developed a method for individual setting of engine moments closely coupled in the course of sheet processing. The authors present a functional block diagram for the control system to implement the method. The rationale is provided for the digital setting of moment controllers switched on the inputs of speed controllers. The authors conducted simulation modelling and comparative analysis of engine speeds and moments at the design and proposed settings. The paper provides the analysis of oscillograms obtained before and after the introduction of the control system developed. Its technical and economic feasibility was confirmed during operation.

Predicting the future trajectories for all vehicles relevant to the ego vehicle is a crucial, yet unsolved challenge to master automated driving. This paper proposes a combination of two lines of research for predicting all the trajectories of a group of vehicles of arbitrary size, considering the mutual interactions possible. Treating the prediction of other vehicles as a planning task for themselves enables the application of the artificial potential field approach. Modeling the driving situation as a potential field turns the trajectory prediction problem back to its original domain - utility space. Humans generate trajectories (that should be predicted) during driving by balancing costs and rewards, which lead to a total utility. The main difficulty inherent to the potential field approach is the hard problem of parameter tuning. Therefore, it is not directly used for prediction. Instead, the potential field representation is used as input for a neural network, which predicts a distribution over trajectories based on distinct maneuvers. This allows a multi-modal prediction for each vehicle and reflects the pattern recognition character. © 2020 IEEE.

Parking into small berths remains difficult for unskilled drivers. Researchers had proposed different automatic parking systems to solve this problem. The first kind of strategies(called parking trajectory planning) designs a detailed reference trajectory that links the start and ending points of a special parking task and let the vehicle track this reference trajectory so as to park into the berth. The second kind of strategies(called guidance control) just characterizes several regimes of driving actions as well as the important switching points in certain rule style and let the vehicle follows the pre-selected series of actions so as to park into the berth. Parking guidance control is simpler than parking trajectory planning. However, no studies thoroughly validated parking guidance control before. In this paper, a new automatic parking method is presented, which could characterize the desired control actions directly. Then the feasibility is examined carefully. Tests show that a simple parking guidance control strategy can work in most parallel parking tasks, if the available parking berth is not too small. This finding helps to build more concise automatic parking systems that can efficiently guide human drivers.

The process of identifying key information in unstructured sets of textual information is complex and multiple-aspect. In this regard various methods and technologies are being actively developed that can improve the analysis process and reduce the gap between the quality of the obtained results and the computational resources required for the analysis. This article provides an example of an alternative method for determining information proximity in large arrays of textual information. A distinctive feature of this method is the application of spectral conversion of the information and means of descriptive logic for the logical inference of analysis results of the text documents array. The main components of the method as well as conditions and statements of the logical inference of the analysis results are considered. The analysis of the obtained results based on the results of the approbation of the method is given. The obtained results clearly demonstrate the possibility of applying the method for semantic classification problems in information decision-making systems. © 2020 CEUR-WS. All rights reserved.

the article solves the problem of multicriteria optimization of technological parameters of the butyl reclaimed rubber production process. The search criteria for the values of the optimal operating parameters at the stages of ionization irradiation and thermomechanical treatment are formed. The connection structure and competitive relationships between particular and general optimization criteria is presented. As methods of aggregating the generalized criterion, the method of linear convolution of criteria and the mathematical apparatus of the Choquet integral in conjunction with the vector of values of the Sugeno fuzzy measure were used. On the basis of mathematical models of individual process stages using a genetic algorithm, computational experiments were carried out, as a result of which the optimal values of the vector of control process parameters were found. It was found that the use of the Choquet integral as an aggregator provides the choice of such technological parameters of the process stages at which the heat treatment time is reduced by more than 2 times while obtaining comparable values of the product quality indicators relative to the values of the parameters which were found when implementing the linear convolution method. This allows us to use the proposed mathematical apparatus as an algorithmic support system for decision-making in real production conditions. © 2020 IEEE.

Today information systems are used in all spheres of human society. The main criterion for the optimal operation of an enterprise information system is complete automation. This is especially important when one needs to handle huge data streams. In this regard, the implementation of automated control systems is urgently necessary. They significantly increase efficiency in all areas of production and improve employee productivity. In this case, it is necessary to pay special attention not only to the creation of a unified information environment, but also to the possibility of assessing the workload and functionality of its individual components. Such an opportunity is provided by the application of the foundations of constructing functional models of subsystems.

Modern electric grid companies are focused on minimum economically feasible costs and are aimed at improving the efficiency of financial and economic activities through the rational use of resources. The digital twin structure is proposed for the management of field service teams in the event of accidents and technological failures in an electric grid company. The digital twin includes an agent model, a system dynamics model, a geographic information system component, and modules with experiments. The description of the simulation model of management of field service teams in the event of accidents and technological failures is formalized, the input and output information on the model components is highlighted, the information is structured, and the scheme of the system dynamics model is created. Experiment designs for the digital twin of the management of field service teams in the event of accidents and technological failures in order to determine the best reliability and cost indicators are developed. The developed approach can be used to create digital twins of the management process of field service teams in the event of accidents and technological failures for various electric grid companies by selecting the parameters of simulation models according to the statistical reports by electric grid companies and connecting the appropriate GIS modules.
