The article discusses current issues and problems of developing systems for evaluating the effectiveness of managerial decisions on market segmentation at the enterprise level; the classification of mutual influences of market segments is made in order to identify the groups that have the greatest impact on the efficiency of the production and economic activity of the enterprise. The study of these issues showed that it is from the decisions taken at the planning stage that the network can ensure a stable increase in the company’s production indicators. A comprehensive assessment of management decisions made in the field of segmentation of the sales market is an urgent task for every enterprise striving for prosperity. However, as analysis shows, this problem has not yet received a proper solution. In the process of considering the above problem, a mathematical model was described and an algorithm was developed that provides an assessment of the effectiveness of management decisions on market segmentation at the enterprise level. This approach allows you to quantify the effectiveness of management decisions on segmenting the sales market of products manufactured by commercial enterprises, according to the following criterion: a management decision on market segmentation will be effective if the current sales volumes of products in the selected market segments are not less than the specified values. The developed five-stage algorithm is aimed at widespread use by commercial enterprises in the conditions of market competition.

Keywords: efficiency, criterion, mutual influence, model, algorithm

The article introduces a description of one of the classes of complex systems – geographically related organizational systems, widespread in the social and economic spheres. The characterization of the systems under study is given through classification features according to their belonging to territorial and industry clusters, according to the method of spatiotemporal information generation for effectiveness evaluation. A variety of combinations of these features leads to the three main tasks of geographically related organizational systems management: management of resource, productive and resource-productive interaction of objects of the main and related systems.It is represented that the mechanisms of the generation of spatio-temporal information play a special role in the intellectualization of decision-making in the listed managerial tasks. Such mechanisms are monitoring and rating. The first mechanism allows obtaining estimates of indicators characterizing the functioning of the main system objects and the results of interaction with objects of related systems in a set period of time. The second mechanism is aimed at aggregating the monitored indicators into an integrated assessment, based on which the position number of the main system object in the rating list is determined. The main fields of intellectualization of management of organizational systems class under the study, which are determined by the optimization condition of potential efficiency and require the development of problem-oriented methods for analyzing GIS-oriented spatio-temporal information and algorithms of decision-making intellectual support are substantiated.

Keywords: organizational system, management, interaction, efficiency, intellectualization, spatio-temporal information.

doi:10.26102/2310-6018/2019.25.2.019

V.V. Salnikov, Y.V. Frantsuzova


The paper considers an approach to the energy analysis of control programs (up) for multi-purpose machines (MCS) with a numerical control system (CNC), the purpose of which is to assess the efficiency of energy consumption when it is performed on a certain equipment. Describes the General approach to programming of CNC systems with the help of ISO-7bit. The description of the grammar of ISO7Bit language is presented with the help of metacharacters for constructing the syntactic and lexical analyzers of the text of the control program on its basis. Considered the authors developed software for analysis of control programs with the goal of getting out of the text up the contour of the workpiece, cutting speed and feed in each point of the trajectory, and calculation of the data obtained cutting power and chart your energy consumption by machine drives system. To demonstrate the capabilities of the developed software, an analysis of the control program obtained at the enterprise of the Tula region was made. As a result, a number of measures are proposed to improve the energy efficiency of its implementation: reducing the “irrational” idle tool strokes and optimizing the feed value at the time of processing the “depression”. Directions for further modernization of the developed software are shown.

Keywords: efficiency, energy use efficiency, energy efficiency program operating ISO7Bit

V.I. Sumin, O.V. Isaev, M.V. Skulkov


With the purpose of ensuring highly reliable information processing in practice at assessment of stability of functioning of the security systems considered from positions of information structures in the conditions of negative impacts, it is necessary not only to develop new models and algorithms of steady interaction of elements of the specified information sets, but also to consider requirements to efficiency of the information processes proceeding at the same time. Increase in amount of negative impacts on elements of security complexes demands modernization of systems of parrying of negative impacts and also carrying out the analysis of stability of functioning of this sort information structures. The improvement of information structures and optimization of information processes made on the basis of development of adequate models of functioning of systems of complex safety of objects of special importance in the conditions of factors of external influences is a scientific and technical task relevant now which implementation will allow to minimize lag of rates of development of the security equipment and technologies from dynamically improved instruments of destabilization of elements of systems of protection of objects of special importance. Development and the solution of adequate mathematical model of interaction of information structures of security systems and negative impacts are intended to describe dynamics of evolution of their elements on the phase plane of space and taking into account integrated representation of stability conditions and also the second method of Lyapunov to create mathematical model of steady management of information process of interaction of elements of the specified information sets. The task of the analysis of phase portraits of a condition of security complexes as information systems is connected with a research of the attractors representing areas (the phase vicinities) of space consisting of set of concentric circles in the form of a set of the points which are attracting trajectories of evolution of elements of information structures of security systems and indicating areas of their steady functioning.

Keywords: attractor, algorithm, dynamic system, stability, efficiency, information system, information structure, information process, information set, interaction model, management.
