FRAME EXPERT SYSTEMS USING NEURAL NETWORKS
05.13.18 Mathematical modeling, numerical methods and software complexes
DescriptionThe study was carried out with the financial support of the RHNF as part of the research project of the RHF RFBR 17-02-00475а "Application of metaheuristic algorithms for solving direct and inverse problems of optimizing the management of spatially distributed complexes"). The article discusses the use of artificial neural networks in frame expert systems, which in some cases make it possible to bypass a number of limitations of the standard version of frame expert systems. Several options for using neural networks in frame expert systems were considered and a number of tasks to be solved for each

PHYSICAL MODELING OF ODOMETRIC COMPRESSION OF SAND
DescriptionThe odometric compression of sand with constant rate of loading (CRL) or constant rate of deformation (CRD) and continuous registration of the corresponding reaction allows to identify the effect of stepwise changes of deformation (at the CRL) and the power reaction (at the CRD). Physical modeling of compression on the sandy model showed the same effect. The physical model was made of fine sand with marks, mimicking large inclusions. Compression of the soil at the CRD was uneven, stepwise, and the strain rate of the upper boundary of the sandy model changed cyclically. Maximum amplitudes of cycles passed through a maximum. Inside of the sand model, the uneven strain resulted in the mutual displacement of the adjacent parts located at the same depth. The growth of external pressure, the marks showed an increase or decrease in displacement and even move opposite to the direction of movement (settlement) the upper boundary of the model ‒ "floating" of marks. Marks, at different depths, got at the same time different movements, including mutually contradictory. The mark settlements sudden growth when the sufficiently large pressure. These increments in settlements remained until the end of loading decreasing with depth. They were a confirmation of the hypothesis about the total destruction of the soil sample at a pressure of "structural strength". The hypothesis of the "floating" reason based on the obvious assumption that the marks are moved together with the surrounding sand. The explanation of the effect of "floating" is supported by the fact that the value of "floating" the more, the greater the depth

Description
Innovative tools of intercompany and strategic planning are designed to form interconnected tasks structural units of industrial enterprises and complexes in the sought after amount based on the cost of production of interdependent. Intercompany planning has no tools based on chain planning with cyclic calculations. Allocation of factors affecting business performance is a mandatory procedure in the development of innovative tools and intercompany strategic planning in industrial plants and complexes. Factors determining the efficiency of intercompany and strategic planning at industrial enterprises and complexes require detailed classification. The article examines the factors that determine the effectiveness of intercompany and strategic planning. The classification of factors, that are offered, which can form a conceptual framework of business development strategy for a long period of time, based on the use of interrelated production plans for the following criteria: conceptual, stabilization and functional. The developed classification of factors, which determines the efficiency of intercompany and strategic planning, allows us to: generate the concept of strategic business development; establish the optimum parameters of the structure and volume of internal and external supply, to determine the required size of lending and investment; achieve stabilization of interests of the economy and the level of investment attractiveness of the business, etc. Based on it, becomes possible to develop a methodology and logical approach to the formation of innovative tools intercompany and strategic planning at industrial enterprises (complexes)

HARDENING AND SOFTENING OF CLAY SOIL
DescriptionHardening of clay soil manifests in the form of increase of the resistance of sample to shear deformation. The shear tests of normally compacted and overcompacted soils give values of peak strength at small strains and long-term strength at high. A shear test with constant strain rate of deformation (CRD) with continuous recording of resistance encounters uneven resistance change and the cyclical rate of change of resistance (RCR). The identification of cycles of the SIS allowed us to divide the deformation in each cycle for elastic and inelastic, corresponding to the ascending and descending branches of cycle. On an interval of the total resistance, the increases of the increment of inelastic strain are positive up to some critical value of the total deformation of the sample at which their sum reaches a maximum. This maximum is adopted as a measure of hardening. With further shearing of the sample, inelastic increments are negative, and their sum is monotonously decreases and reaches negative values for the total destruction of the sample. This value is taken as the softening. A symptom of total failure of the sample is the decline of absolute values of inelastic increments of resistance to zero. In general, the trend of the increments of inelastic and elastic increments of the resistance of the sample indicates the development of the destruction of the soil sample on the sliding surfaces and, in particular, yielding of the total surface. The sum of elastic increments of the resistance monotonically increases throughout the shear
