Decision making in the organizational and technical systems is complicated by the risk of various events emergence in the systems with a given probability. The article describes a method for supporting decision making under risk on the basis of integration of evolutionary, multi-agent, simulation models and numerical methods. In the course of the method's work the following steps are performing: a set of alternatives solutions is formed;  transition to a one-criterion alternatives evaluation is fulfilled by using linear convolution; transition to the system behavior certainty is fulfilled with the use of numerical optimization Bayes-Laplace criterion. The developed method is applied to solving the projects scheduling problem; the results agree with the problem solution that has been performed by using genetic algorithm method under certainty.

  In article the information system of the MANAGEMENT information system is represented as the three-level model constructed by a principle of cascade maintenance. Problems of delays of the supply with information, formations arising at the expense of delays and data transmission are considered. The mathematical model of system intended for optimization of maintenance on parameter of delays, on the basis of priorities of processes of formation and an information transfer is developed.

  Proposed to use a sensor based on surface acoustic wave (SAW), which represents a delay line with unidirectional interdigital transducers (IDT) for measuring the pressure in the liquid. Reflective IDT loaded by series connected inductor and two capacities. One of these capacities - this trimmer, and another - a membrane capacitor whose capacitance depends on the pressure. When the pressure changes of the membrane capacitance capacitor, which changes the reflectivity of the reflective IDT. The magnitude of changes in this ratio determines the pressure applied to the membrane capacity.

This paper focuses on defining the elements forming the political tension - on the emotional component of a group of political attitude. Baseline data were obtained by questionnaire. All were interviewed 66 patients. Respondents were asked to rate 20 attributes-antonyms two "ideal", positive and negative political orders. And two real order: in Region and in Russia as a whole. It is shown that the investigated audience is characterized by low political activity, and the activity of the emotional perception of the existing orders of magnitude higher than the perception of ideal constructs. An unexpected result of a negative perception of the political order in Russia in a whole, the local order in due permanent stressful situation for the given audience. People normally (or neutral) treat policy which always acts them through region policy. And of the troubles accuse (probably unconsciously) change of a political system which associates at them with center policy.

  The article deals with the scientific principles of modern cognitive modeling offered in foreign practice to combine already existing and new models in the future in the form of cognitive architectures. Our approach is based on the concept of a unified theory of cognition, described by Alan Newell, which offers the general provisions for cognitive models used in all areas. In the computer environment, the theory is realized in the form of cognitive architectures. Shown, cognitive architecture is a system integration of static and behavioral models, which provides a solid approach to modeling knowledge of social processes, from the empirical data to quantify the simulation  of results, from level of the neural description to system level, thus the cognitive model is scaled to higher level with preservation of qualitative properties, and as a platform for integration the storage of data serves. Formally described by the level of integration corresponds to the construction of integrated information environment that combines unified storage of data with appendices of analytics.

  The results of the analysis of gravitational and magnetic fields of the Tersko-Caspian depression are introduced. The main feature of the potential fields of the region is the presence of high-gradient zones. Distributions of azimuths of gravity and magnetic lineaments testify to the coincidence of the basic maxima on histograms of directions of gradients. About the general nature of these zones caused fault tectonics.
