The authors consider the research of effectiveness of coevolution genetic programming algorithm and its applica- tion in the problem of model analysis of the phase boundaries of magnetic state of a crystal.

The authors offer to use genetic programming techniques to solve variational problem. Two solving variants of finding solution are described. Features of the problem solution are considered. Results of numerical experiments are given.

The authors present the analysis of modern systems, mathematical models and methods for planning and manage- ment of the described production. Optimization criteria for workshop scheduling are considered, computational com- plexity of scheduling optimization problems is estimated. A model of multi-criteria optimization of discrete production manufacturing scheduling problem is suggested. The model takes into account all technological restrictions.

A mathematical model for mass transfer process in rectification columns of poppet type is obtained. At the result of the investigation the ordinary differential equations system is obtained with the transition to equations in partial deriva- tives. Investigations of processes of detection establishment of mass transfer processes in dynamic regimes are per- formed. Static and dynamic characteristics for industrial rectification columns are calculated.

The paper is devoted to theoretical and practical problems of a servo system of automatic control. The dynamical system of the working body with hydraulic stacker is considered. The task of development of a simulation model of automatic control system of the working body of the Stacker is considered with the use of Matlab & Simulink program. The results of the study are presented. The proposed method of modeling of adaptive systems of control of nonlinear dynamic objects, on the example of the tracker system of a stacker, with the account of dynamics of processes in the drive, in which the operating deviations decrease.

One of the ways of representation of knowledge (theories) by means of functional grammars is considered in the article. The authors make an attempt to give the uniform scheme of the decision of the problem, by its downsinking in functional grammar of the theory.

The analysis of ways of boosting of efficiency of performance of highly mobile subscribers in a network of broadband access is carried out. The fundamental attention is given to the use of the adaptive circuit of modulation. The algorithm of estimation of bit rate with use of the mechanism of acknowledgement of reception is offered.

The authors consider approaches to selection of effective structures and composition of high-performance hard- and software systems for information processing. A comparative analysis of centralized and distributed approach to implementation of such systems is performed. The results of patent search, which reflects the contemporary trends and global level in this object domain, are presented.

The author considers a terminal control task solution method for nonlinear dynamic systems, method is based on evolutionary strategies algorithm modification. The control function synthesis is reduced to ideal two-step relay charac- teristics determination.

The article shows how advanced symmetries of plane ideal plasticity influence on exact solutions. New solutions are obtained.

In the article the results of working out of technical shape of LOX-LH2 Expander Cycle Liquid Rocket Engine (LRE) for expandable Orbital Transfer Vehicle, by means of mathematical model of multi-criteria optimization of design pa- rameters, are described. As the criteria of optimization, the maximum weight of a payload and the minimum specific cost of transferring of a payload into a target orbit, are chosen. The calculation of optimum design parameters of LRE for expandable Orbital Transfer Vehicle for four problems of orbital transfer, defined in the characteristic speeds of inter-orbital transition, is resulted: 2500 km/s, 3500 km/s, 4800 km/s and 7000 km/s. On the received optimum design parameters, the design parameters of units of LRE are calculated and the technical shape is constructed.

An experimental inspection of technical possibility of implementation of a way to strengthen the structural elements was carried out as well as a research of effects on structural and geometrical characteristics of a deformed circuit rein- forcement on endurance life of flat samples with a central round opening was conducted.

In the article the description of device, which provides automatic positioning of electron beam relative to joint of welded parts during welding, is given. Search of the acme, based on synchronous detection of sensor signal (X-ray or secondary emission) is realized in the device. Measurements were made when beam goes out of the channel following the welding direction.
