The problem of conflict-optimum counteraction of small groups of aircrafts in the form of two-stage procedure of ranking-allocation and conflict optimization by Nash for obtaining the stable-effective decision in the shape of matrix of conflict-optimum target setting is considered. Calculating time in the case of the exhaustive search is far from real-time, therefore the procedure of thinning of the counteraction effectiveness matrix is proposed, as a result the operating speed for the problem of counteraction of 4-by-4 aircrafts is rising twenty-fold.

The paper shows formation of common cultural and professional competencies of Applied Physics students at Petrozavodsk State University in the course of performing their research work. It is suggested that the graduates’ cultural and professional competencies should be assessed according to the list of these given in the respective federal state educational standards.

By virtue of importance of noise reduction of vehicle tires in 2005 UNECE approved the following regulations: “Uniform provisions concerning the official approval of tires with regard to the road roar.” Thus, creation of low-noise tires and their acoustic characteristics control is an important task.The article touches upon the basic problems of creation of techniques and systems providing fulfillment of conditions during measuring. This concerns fulfilling both acoustic and mechanical requirements to constructions-in-progress. The article covers the approaches to creation of devices for benchmark tests and road tests at measuring tire acoustic performance. A new design of surface profilometer is offered.

This article covers solving one of the tasks of enterprise equipment repairs control system - tasks of planning maintenance service and repairs of industrial enterprise technology equipment.

Dynamical interactions in mechanical oscillation system are considered, in which object of protection is connected with additional mass through kinematical couple. Is shown that introduction of additional ties if there is absorber of oscillation may change frequencies properties of the system significantly.

Approach of change of dynamical condition of vibroprotection systems through  introduction of additional connection force influence are considered. Such approach accordances to form of  automatical control by force of influence.

This article deals with BMSTU collection of centrifugal governors collected at the end of the 19th century.  It gives a brief description of governors, their distinctive features and working principles; article also provides information on the history of their creation and production.  Main problems of the governors and solutions, suggested in publications of Maxwell, Vyshnegradsky and Chebyshev, were analyzed. Wrong directions in the development of governor design were identified. These mistakes have led to the creation of invalid mechanisms, which can be found in the collection of BMSTU. The experimental determination of governor’s characteristic is described; also 3D models of several governors, created by authors, are shown.

General questions of mathematical modeling of mechanical oscillation systems with couplings are considered. The article covers an extension of a well known theorem about superposition effects.

The article shows the opportunity and expediency of using liquid hydrocarbons during thermal treating of Lysakovsky gravitational-magnetic concentrate for metallurgical redistribution.

The article covers a methodology of determining random hydrodynamic loads on the fuel rods beam of WWER fuel assembly by coolant turbulent flow; the methodology is based on measurements of pressure fluctuations distributions on the external perimeter fuel rods beam. Data on random  hydrodynamic loads on a start-up hydrodynamic station and in the area of steady currents for different conditions of input flow pattern formation.  There are two typical areas of influence of random hydrodynamic loads on the intensity of fuel rods beam vibration.

Questions of building of mathematical models of dynamical absorbers as additional feed beck ties in vibroprotection systems are considered in difference from usual ideas the structure of  original model of protection of object. Nase big influence on parameters on conditions of dynamical absorbtion; it is depend from particulates of structure of system of external forces.

The analysis problems of principles and methods of distribution and products promotion in competitive environment as well as game models of the choice of management strategies for product sales are considered.

At the same time to implement the interaction of user processes between main stream of the scenario and supporting processes the formal operations of data exchange and synchronization are introduced.

The article considers the architecture of an information management system containing information-technological, interactive and organizational platforms interrelation between which is carried out with the help of dataware outline. The information-technological platform acts as an informational and technological basis for input, processing, storage and management data distribution. The organizational platform is designed to control the process of development of new management methods on the basis of information technologies. The virtual platform allows to activate opportunities for all participants of business: customers, employees, private investors. Architecture landscape changes opportunities for enterprise management, while reacting minimally to the changing environment - both of production and the market, and plays an additional role of added value generator.

The paper considers the possibility of classification of organizational and technological decisions on the following levels: 1) accounting system of data processing, 2) complex systems of information processing; 3) the integrated information system; ( 4) dynamic control systems. It is shown that the accounting system, will allow to show the result of a major business and financial operations. The decision of complex level focused on the operation of the control loop "planning - accounting - control - analysis" in the complex. Integrated control systems of the enterprise allow to generalize the assessment of the state of processes of management of all resources of the company. WITH the help of dynamic technological-organizational structures are formed control systems with distributed in time and space resources.
