Today, development of Russian economy is inseparably connected with the application of high technologies
and the practical introduction of radical innovations. In managing the project to create hightech
products analysis of its implementation prospects plays an important role. It should be based on
assessing the sufficiency of the internal resources and the accumulated potential of the enterprise, the
favorable external conditions. The specific features of innovative activities, related to the statistics
lack, have necessitated the usage of data mining techniques. In the article it's suggested the economic
and mathematical apparatus for the diagnosis of various elements of internal and external enterprise
environment, based on the modified algorithms of growing pyramidal networks. The modification is
involved using the fuzzy logic methods to find reasonable single decision under the conditions of uncertainty.
The fuzzy inference algorithms are applied to calculate the connection power between the
factors and conditions and the vertex significance. The neuro-fuzzy classifier is used to get an aggregate
assessment of the various indicators — the characteristics of internal and external enterprise environment.
These methods are implemented as the expert-diagnostic system, which is built using the
server pages of database Caché and tools of mathematical package MatLab. It is expected that the application
of the described tools will enhance the validity of accepted decisions and reduce the errors
in the initial stages of the project lifecycle.

Major international airports have rather complex service structure. Insufficient attention to the management
of the airport departments organizing service system has a negative impact on passengers
who are facing with the uncomfortable organized control of documents, delays in the inspection of
baggage. The article there was proposed the algorithm for the simulation modeling of passenger service
systems also was conducted testing model. The model takes into account passengers which are
came to the airport individually or as a part of group. At the stage of baggage reception we can view
one group of passengers (ex.: family) as a one requirement which passes the first type of channel service.
Then group goes to the queue of the service channel of the second type — checking documents
and personal inspection. In this case each member of the group is serviced separately. After that the
passenger is considered to be serviced and passenger is awaiting the beginning of the planting. Was
presented algorithm and software to calculate the characteristics of passenger service at the stage of
registration. The article posed and solved the problem of multicriteria optimizing parameters the mass
service system of the departing passenger at the stage of registration of luggage, preflight inspection of
documents and personal search at the airport «Orenburg». Created simulation model of the mass service
system can be used for planning the work of officers serving passengers departing flights at the airports.

The article discusses issues related to the solution of the problem providing semantic interoperability
in the financial organization. Interoperability is an ability of the joint operation of automated systems
and consists of technical and information. Problems associated with the technical interoperability in
modern IT systems generally are solved. Technical interoperability studies related to problems solution
of performance, reliability, cryptographic data protection, cost optimization and etc. Automated
systems must use the information in compatible manner, in a certain sense, must exist a «same understanding
» the content of the interaction between them. It must be formed common semantic field.
Financial organizations use the semantics to harmonize their data by available government public information
to interact with each other. Automatic integration method is a qualitative development expert
method. One of the important indicators of integration is the proportion of incompatible semantically
mapped information sources. Such an assessment may be obtained in two ways: automatically or
expert. Automatically obtained estimate can be computed by embedding the special algorithms, which
record discrepancies in information (rejected transactions). Another indicator of interoperability is a
number of attributes (tags, facts and etc.) that can be obtained from this information block. Means of
semantic interoperability in demand at all stages of the life cycle of the automated systems. The article
suggests some approaches to quantitative and qualitative assessment of effectiveness of existing
integration technologies. Attempt to understand how quantitative estimates and qualitative aspects of
this phenomenon is made.

Method and algorithm had been developed for analysis of amplitude-frequency characteristics of
turbulent compressible gas flows using the multifractal spectra. In multifractal analysis we used images
of hydrodynamic characteristics of gas flows that had been calculated by computer modeling. In
this case the «particles in cells» model had been used. The resulting images of hydrodynamic characteristics
were used to calculate Holder exponent. As a result of Holder exponent calculation we have
got so called α-images. These α-images were used further to calculate multifractal spectra. The calculations
were made for gas flows in the convergent tube. The multifractal spectra were used to calculate
generalized fractal dimensions, namely: fractal dimension, information dimension and correlation
dimension. It had been demonstrated that parabolic approximation of multifractal spectra is sufficient
to describe frequency characteristics of turbulent gas flows in the convergent tube. It had also
been proposed to use the correlation dimension as one of the frequency estimation criteria for turbulent
compressible gas flows in pipes.

Actual questions of the learning philosophy and methodology informatics in univercities is consider.
The rewiev of the philosophy and methodology of the technical sciences and informatics how scientific
direction and educational subject to postgraduates and students is provided. For example of the modern
textbook problems of the lag behind educational subject from modern Russian scientific works to
methodology informatics is consider. The association of the philosophy and methodology informatics
subject with informatics history in «common informatics» boards to propose. Modern Russian textbook
to philosophy and methodology of the technical sciences and informatics by professor V. A. Kanke is
is consider. It’s very useful and interesting textbook, however, it’s not free from large defects. Author
give original classification sciences, original review of the history and development philosophy and
methodology science. Also author introduce very original definition «tekhnicologies» sciences instead
of technical sciences. That and other new and original proposals is very useful and interesting, however,
without serious discussion that proposals cannot be maintenance of any the universities manuals.
That wistful resume must to very useful and interesting book. That book now must name only
scientific monograph. Any question of the methodology of informatics in that article also is consider.
