The hybrid risk management methodology in sociotechnical systems is based on combining capabilities of different artificial intelligence technologies and makes it possible to introduce advantages of several technologies by integrating them. Six stages of research carried out within the framework of hybrid technique are presented, as well as mathematical description of the neural network model. Effectiveness of the proposed methodology was tested using three implemented software products.

Scientific literature is paying insufficient attention to calculation of the deformation processes of workpieces exposed to viscoplasticity. Relationships are proposed to determine stresses and continuity of the workpiece material during drawing in heating the cylindrical products with a thinned wall. State of hot material viscoplasticity is accepted under the plane deformation scheme. Equilibrium equation, yield condition for anisotropic material and discontinuity kinetics equations were used making it possible to predict strength characteristics and accuracy of the products obtained. Calculations of the drawing process modes for workpieces made of the AMg6 aluminum alloy and of the VT6s titanium alloy were performed. Graphic dependences are demonstrated of alterations in the operation specific force and in the material continuity value on the motion speed of the deforming punch. At the given forming temperatures, the energy continuity equation corresponds to the aluminum alloy, and the deformation equation corresponds to the titanium alloy. Influence of the workpiece mechanical properties anisotropy on the drawing technological conditions was studied. It is shown that force modes and continuity alteration of the deformed material depend on the anisotropy coefficient at a given temperature.

The presented graphs and calculated Allan variations for the profiles of various surfaces clearly demonstrate that alterations in the surface relief standard deviation during chemical etching of the quartz plates and bars is associated with the surface defects size.

It is shown that in order to preserve physical and mechanical properties of the composite materials, it is required to give preference to the one-process methods in formation of the reinforcing fillers, which could reduce the number of abrasion effects on the fiber. An important factor in reinforcing and creating the carbon-carbon composite materials by winding is the direction of external axial loads, which are known in advance. In order to avoid destruction of the upper layers of the product structure exposed to action of the axial forces, the package should be oriented in such a way that the thread cohesive forces prevent separation (peeling) of the unbound winding turns.

When comparing maximum temperatures on the transistor crystal at the released power of 1 W, it was found that an increase in the thermal conductivity of the additional heat sink contributed to maximum temperature displacement from the upper crystals to the lowers and changed the heat flow direction. GaN crystals use increased the power level over the entire range of thermal conductivity of the additional heat sink materials 500--2000 W/(m · K), and the power ratio with an increase in the thermal conductivity of the additional heat sink was approximately equal to two.
