Abstract. The present work deals with the stability analysis of a banking system with the structure in the form of Apollonian graph based on such characteristics of the banking system as the modularity and inhomogeneous distribution of banks by degree, on the basis of the extended mean-field Nier model (a static approach based on a simplified balance sheet of assets and liabilities of the bank) which was used to analyze the extent of the process of bankruptcy of banks after the default of one of the banks in the banking system. The obtained results of research of stability of banking systems based on the Apollonian graphs indicate that such characteristics as modularity (i.e. clustering), and the heterogeneity of banks in the structure of the model of banking systems allow them to conform «isomorphous structure» typical of the majority of real social and biological complex adaptive systems.
The paper presents the results of scientific research in the field of engineering psychology regarding the creation of a method for selecting a set of psychodiagnostic techniques for the tasks of professional selection and training of specialists in complex ergatic systems. At the present stage, the process of professional selection of specialists of complex ergatic systems is standardized, but its individual components so far remain informal or subjective. This is especially true for the stages of building a specialist standard and the formation of an optimal set of psychodiagnostic techniques. The essential problems of professional selection of specialists are as follows. Most of the methods used to build the standard of specialty are characterized by significant subjectivity and directly depend on the qualifications of the expert who conducts the selection. None of the existing specialist models is universal and in the vast majority of cases has a narrow-profile nature. The lack of formalized models of psychodiagnostic techniques does not allow us to optimally select those that are necessary for the diagnosis of applicants, taking into account existing limitations and resources. When assessing the consistency of experts' opinions, the degree of their competence is not taken into account, which in practice can lead to distortion of the results. The solution of these problems will allow us to develop a system of automated support for building the standard of a specialist's specialty and to determine the specific psychodiagnostic techniques necessary for his professional selection. To do this, it is necessary to analyze the structure of professional selection, develop models of psychodiagnostic techniques and build a set of psychodiagnostic techniques, as well as a method for determining it relative to the constructed standards and available resources. The method of selection of a set of psychodiagnostic techniques for the tasks of professional selection and training of specialists of complex ergatic systems developed in the work can be used to automate the process of professional selection of professional workers of any specialization. The novelty of the proposed approach lies in formalizing the selection procedure for a set of diagnostic techniques as an optimization task. The developed set of algorithms made it possible to formalize the stages of choosing the optimal set of diagnostic methods in order to solve the problems of choosing the best method for a particular property and constructing a number of methods for a set of properties.
The present article studies formation of complex air traffic information model in the operative thinking of operators of the automated air traffic control system. It shows interaction of operators with the color model of the air traffic; characterizes existing models of color spectrum; analyses their disadvantages. The article suggests an algorithm for finding the optimal color spectrum of information model elements; develops and investigates the color component of the information element of a complex air traffic working information model. It analyzes relationship between the quality of information model formation and the efficiency of operators' activity.
Ab s t r a c t. The present article represents structure, content and sequence of steps of the method of adaptive control of the information model's display parameters of the air situation. The problem describes complexity of the particular air situation in automated air traffic control system. The method assumes that the degree of complexity of the situation is recognized on the basis of heterogeneous data received from the sources. According to the results of experimental studies, we show the dependence of the average time of perception and the probability of error-free perception of the information model of the air situation by the operator on the coefficient of the overlapping forms. K e ywor d s : air traffic control; information environment interface; aircraft tracking form; decision-making support; air traffic operator activities; information model.
