It is shown that the study of the processes of the functioning of institutions of higher education and the publication of the results of these studies in scientific journals are mainly aimed at identifying the dependencies of the quality of training specialists in these institutions on one or more coordinates of this process in the conditions of ignoring the influence of many other its coordinates, and in the vast majority without taking into account their changes in time, that is, using mathematical models of these dependencies in the space of Moore's machines, while adequate representation of the processes of functioning of the institutions Higher education is possible only in the space of Mill's machines. It is proposed to use the system approach as an ideology and system analysis as a method for studying the processes of functioning of institutions of higher education and to determine all the components of these processes in the first two stages of the application of the method, as a result of which the institution of higher education identified as an object of research on the environment and formed all points , in which this object of research carries out contacts with the environment, and specifies all 15 environmental impacts on the object of research and all 12 effects of the object and research into the environment. It is shown that in order for mathematical models of the processes of functioning of higher education institutions to represent these processes in the space of Mill's machines, they must be synthesized using dependencies in which all variables are functions of time in its continuous or discrete interpretations. As criteria for evaluating the results, it is proposed to use such integral criteria as the image of the institution of higher education and the costs necessary to ensure its functioning, the first of which — the image — requires maximization with constraints on costs, and the second — the cost — requires minimization with restrictions on the image, that is, when solving the problem with their use, the strategy may be either maximizing, or minimax, and the optimum point is saddle.

The theme is devoted to the actual problem of foundation engineering and soil mechanics - elastic-plastic modeling of the joint operation of the "ground foundation — slab foundation" system in order to determine the bearing capacity of the foundation and the choice of its optimal thickness. The development of the construction industry is associated with the introduction in the building practice of new technologies of predictive calculation. Significant increase in the weight of modern structures, which is transferred to the basis, necessitates the development of non-linear methods for calculating drill piles, which in these conditions are the most effective types of foundation structures. Construction of buildings is a labor-intensive process that requires well-balanced, well-calculated steps and solving complex mathematical problems. This is especially true for the installation of a part of the building, which perceives the load and transfers them to the foundation — the foundation. It is extremely important to provide stability and low occupancy of the structure, thus avoiding its possible uneven subsidence or destruction. To do this, ensure prediction and numerical implementation of calculations of structures. Therefore, the model of the equation of equilibrium of the foundation immersed in the soil medium, which satisfies the Laplace differential equation, is developed. The main calculation equation of the soil model is the integral equation obtained by K. Brebbia. The attachment of numerical MGE to the solution of the nonlinear problem of geomechanics is substantiated by theoretical calculations, supported and illustrated by numerical calculations. Nonlinear task of the process of deformation of bases is solved using step method of O. A. Iliushin The soil was modeled by theory of V. M. Nikolaievskyi and I. P. Boiko. Full deformations were determined, which consisted of increments of elastic and plastic deformations. The layout of the calculation matrix of the influence of the MGE was performed on the basis of the decisions of R. Mindlin. The results of the forecast for the IHE are given on the plot of the "loading-settling" of the base plate. The fidelity of the choice of the settlement dilatation model is confirmed by the correspondence of numerical studies with experimental research.
本课题致力于基础工程和土力学的实际问题——“地基-板基础”体系共同作用的弹塑性建模，以确定地基承载力和选择地基的最佳厚度。建筑业的发展与预测计算新技术在建筑实践中的应用密切相关。现代结构的重量显著增加，这些重量被转移到基础上，需要发展非线性方法来计算钻孔桩，在这些条件下，钻孔桩是最有效的基础结构类型。建筑物的建造是一个劳动密集型的过程，需要精心平衡、精心计算的步骤，并解决复杂的数学问题。对于建筑的一部分的安装来说尤其如此，它感知荷载并将其转移到基础-基础。提供结构的稳定性和低占用是极其重要的，从而避免其可能的不均匀沉降或破坏。要做到这一点，必须保证结构的预测和计算的数值实现。为此，建立了满足拉普拉斯微分方程的浸没在土介质中的基础平衡方程模型。土壤模型的主要计算方程为布雷比亚(K. Brebbia)的积分方程。数值MGE与求解非线性地质力学问题的关系得到理论计算的证实，数值计算的支持和说明。采用O. A. Iliushin的阶跃法求解地基变形过程的非线性任务，采用V. M. Nikolaievskyi和I. P. Boiko的理论对土体进行建模。测定了由弹性变形增量和塑性变形增量组成的全变形量。在R. Mindlin的决策基础上进行了MGE影响计算矩阵的布置。在底板“加载-沉降”图上给出了IHE的预测结果。数值研究与实验研究的一致性证实了沉降扩展模型选择的准确性。
