Y.E. Lvovich, A.N. Shvindt

The paper demonstrates the necessity of forming models and procedures of management decision making for improving the quality of higher education management. The authors examine monitoring results of some higher education institutions effectiveness, alumni employment, student surveys as information resources of such an approach. Structuring of these resources is carried out by means of the indexing theory. In order to implement this multistep procedure of management decision making the authors processed and analysed data through the integral estimation, built ranking arrays and clusterized the educational institutions. As well, the authors used neural simulation of depending the rates of quality education upon the factors characterizing conditions and resources. Optimization models and numeric procedures of decision making providing compensation of the revealed deviations from standard requirements are also developed.

Keywords: education quality, management, monitoring, optimization, neural simulation.

The research urgency is caused by the fact that in the modern dynamic systems modeling and design, researchers do not always have information about its functioning in a given frequency range. This article discusses the technique of prediction of radar characteristics (RС), metal objects containing absorbing components in a certain frequency range, using the information on the scattering properties of the components of these objects. A leading approach to the study of this problem is the use of the apparatus of the green’s function. Scattered electromagnetic field is calculated on the basis of the method of integral equations.

UDC 519.53

M. L. Lapshina, A. S. Chernykh, N.Y. Yudina

The current state of enterprises is largely determined by the economic activity of structural divisions, whose activities are decisive in the production of products for various purposes. For more precise coordination of plans, we formulate and consider the possibility of further optimal solution of the problem of harmonization of optimal plans at the economic level, which can be considered as one of the partial productions of the general problem of the relationship between the local and global interests of an enterprise or a company that has been delivered and studied already in the first economic and mathematical studies conducted both in our country and abroad. The decomposition method is associated with the approximation approach used in the development of a multi-step optimization system for prospective economic plans. The optimal plan for the global task is based on variant calculations of the optimal plans for certain collections of local objects, and it is possible to specify a formal method for distinguishing such structures. A specialized method of decomposing a convex optimization problem is also constructed, describing one of the possible approaches to solving some reconciliation problems. The relationship between product prices, resources and objectively determined assessments of global and local problems is investigated, as well as the possibility of using these estimates in the functioning of the economic mechanism.

Keywords: optimality, model, resources, vector, products.

OPTIMIZATION OF TRAINING COMPONENTS IN THE FIELD OF OPERATION OF AIR TRANSPORT ON THE BASIS OF EXPERT ANALYSIS WITH ORIENTATION ON THE MODEL-ORIENTED APPROACH

UDC 681.3

A.S. Borzova

At present, the requirements to the quality of training of specialists are increasing, which determines the need to restructure the goals and content of training. The difficulties of constructing the optimal sequence of training lead to the need for a model of the content of training, which is a complex structure that includes the components of the system, as well as bilateral and multilateral ties between them. The content of the training is presented in the form of a hierarchical system, the basic task of which is to evaluate higher levels, taking into account the interaction of different levels of the hierarchy, and not directly dependent on the elements at these levels. Each element of the target tree under consideration is characterized by a coefficient of relative importance that determines the proportion of the contribution of this element to the achievement of a goal common to the whole system, which are determined using one of the expert methods, the paired comparison method. Based on the constructed goal tree, which forms the content of training, the main components of the learning process are developed. The sequence presented determines the fulfillment of all the most important requirements to the profile of training the specialist as a whole, as well as the preparation of the necessary base for studying any discipline. Formation of the optimal sequence of studying the components of educational programs is carried out on the basis of the implementation of the algorithm of optimization choice.

Keywords: content of training, learning elements, goal tree, matrix of logical connections, coefficients of relative importance.

DYNAMIC ADJUSTMENT OF MULTIPOSITION OBSERVING SYSTEM

UDC 519.68:15:681.5

V.M. Grinyak, T.M. Grinyak, Y.S. Ivanenko

Current paper is about problem observation system based on range or range difference measurer. The paper discusses the formulation and approaches to the solution of the two-coordinate task of the exhibition (local coordinate binding) of a multi-position system intended for monitoring mobile objects for various special purposes (underwater, surface, surface, air, etc.). Such systems continue to be relevant both for traditional navigation tasks and for new types of surveillance tasks, for example, navigation of mobile devices based on GSM or WiFi data. The mathematical model of the exhibition problem based on equations of the “state-measurement” type of continuous type and finite-dimensional representations of the method of least squares is formulated. Because of the initial nonlinearity of the problem, it is proposed to linearize it about some support solution that characterizes the a priori notions of the state of the observation system. Attention is paid to the problem of resolvability of the problem from the point of view fundamental resolvability (observability) and resolvability in conditions of instrumental measurement errors. The first aspect of solvability is interpreted by the completeness of the rank of the corresponding system of linear algebraic equations, the second by the conditionality of the problem and the convergence of the iterative estimation procedure. The results of numerical simulation of the problem for typical situations are presented. It is shown that achievable accuracy of the exhibition is sufficient for a qualitative solution of navigational problems.

Keywords: beacon system, observation, navigation, positioning, observability, conditionality, range, distance difference.

ANOMALY DETECTION IN SENSOR DATA IN APPLICATION TO THE ANALYSIS OF MARITIME VESSEL MOTION

UDC 004.85

A.A. Sholokhova

The article describes algorithms for anomalies detection in the sensory data in the application to the analysis of maritime traffic. The modern vessel is equipped with many sensors, continuously recording the performance of its various subsystems. The collection and storage of such information provide the possibilities of using intelligent data analysis systems. These tasks concern both the issues of ensuring maritime traffic safety (analysis and prevention of dangerous maneuvers) and the problems of increasing economic efficiency (increased fuel consumption) for ship-owners. The onboard sensors can generate numerical data with a frequency from ten seconds for telemetry up to one minute for navigational parameters. Given such a large amount of information, it becomes obvious the need for the development of automated decision support systems. Applied areas of such systems can serve tasks of preventing dangerous maneuvers, predicting maintenance, preventing collisions, optimizing fuel consumption. In the article, the application unsupervised learning for the analysis of navigational data (ship coordinates, speed, course, depth, etc.) and an example of predicting of fuel consumption based on regression models are considered. A description of various mathematical approaches and its demonstration on real data is given. In conclusion, the possible development and improvement of the given methods are considered.

Keywords: anomaly detection, sensor data, extreme maneuvering, prediction of fuel consumption.
