Construction of standard aircraft turns in relation to the return point to the path line
Authors: Markelov V V 
Published: December 2019

Abstract
The trend of development of modern on-board aircraft systems causes the emergence of new requirements, in particular, to maintain the specified accuracy characteristics while the air navigation. One of these requirements is the implementation of reverse flight schemes, which include standard turns and final turns with the control of the exit to the line of a given path with the return course. Taking into account the fact that the reverse schemes do not solve the problem of providing an exit to the line of a given path at a given control point. The method of using alternative reverse schemes is proposed to solve the problem of ensuring the end of the reversal in the reverse schemes at a given point. The given point of the exit on the path line with the return course is applied as a reference control point in these schemes. The presented method provides the construction of standard turns in relation to the point of return to the path line. The method is used in the preparation of schemes of turns and is used by the onboard aircraft navigation system when flying according to these schemes. The method allows to ensure the end of the turn with the exit to the line of a given path at a given point, as well as to reduce the area of the protected space of the turn zone.

Published: December 2019

Abstract
The focus of research is a discrete-event simulation model of the production process, including many technological operations, the time duration of which should be considered as a random function of several discrete variables. It is assumed that a limited amount of available statistics allows us to construct estimating distribution functions of the random function concerned only for individual values of its arguments. The estimates obtained in this way are suggested in order to be used to form the estimating distribution functions of the random function for any values of its arguments by the methods of histogram arithmetic. Results of the use of the proposed approach, implemented within a computer simulation model of a transport technological process are considered.

Authors: Zimin A V , Burkova I V , Kravets O Ja , Zimin V V 
Published: December 2019

Abstract
The generalized dual problem (GDP) is formulated as a search task of the upper bound minimum (lower bound maximum) for the optimum obtained by solving discrete linear and nonlinear problems by the network programming method. The need for GDP solution arises when, in order to meet the applicability conditions of the method, the right side of the constraint is divided into several unknown summands. The GDP consists in finding of such a partition that ensures achievement of corresponding minimum (maximum). There is no evidence for an existence of the GDP solution for today. However, the conditions for the GDP optimum solution have been formulated. The article proposes an iterative mechanism for search solution of the generalized dual problem. This mechanism is based on the software implementation of the procedure for solving the optimization problem by means of network programming. The application of the mechanism is illustrated on the developing competences task of IT services users. It was shown that the GDP solution exists and is not the only one.

Published: December 2019

Abstract
The complex structure of modern production involves the development of innovative algorithms for servers control. It is necessary to take into account the structure and organization of the enterprise for a long planning horizon. In addition to the intellectual processing of data about the external environment, economic calculation is required. Currently the ways used for solving problems by methods of mathematical programming are insufficient, since production and commerce over the past decades have been combined into branched transnational networks. In this paper, an approximation approach to the analysis of evolutionary problems is proposed. The modeling of industrial-commercial networks using graph theory is applied. Spatial variables that strike the entire spectrum of indicators of the current activity of the enterprise have been introduced.
