Тhe article presents the results of research, review and analysis of long-term practice of dispatching control and modernization of classification of dispatching control techniques used in sites, marshalling yards and nodes. Aim: to expand and upgrade the classifier dispatching the adjusting techniques used at stations, marshalling yards and at the nodes. Method: analysis of regulatory techniques carried out by train precinct and hub dispatchers since the beginning of the XX century. Results: the implemented researches of dispatching regulation allowed to expand and modernize the classifier of dispatching regulating methods, taking into account two features of their Association into groups: the principle of the nearest goal and the level of infrastructure development. Practical significance: the results of the research contribute to improving the efficiency of dispatching regulation of the operation of Railways.
Background. This article presents the composition and algorithm of the automated control system for the parameters of a pneumatic arch-breaking system installed on bunkers with bulk materials. The relevance and practical significance of the issue considered in the article is determined by the fact that when unloading bulk material from the hopper, various violations of the technological process may occur, manifested in the formation of material freezes inside the container, a decrease in the amount of unloaded material, segregation, up to a complete stop of unloading due to the formation of arches. Materials and/or methods. Methods of mathematical modeling, system analysis, comparison, systems theory, as well as architecture and mathematical model of a recurrent neural network with feedback are used. Results. The composition of input and output parameters of the control system is substantiated. Methods for solving problems of classifying parameter sets are considered and an artificial recurrent neural network with feedback and with a sigmoidal activation function of neurons of the hidden layer and a linear activation function of the output layer is selected. Conclusion. The article analyzes the requirements for the system of automated control of the parameters of the pneumatic arch-breaking system. Based on the analysis of possible states of the system, the composition of the system elements and the sets of input, intermediate and output parameters of the system, as well as the objective function of the system operation, are substantiated. It is shown that the system can be built on the basis of an artificial neural network. The algorithm of the automated control system for the parameters of the pneumatic arch-breaking system has been developed.
