In this article, the author's approach for research of
financial and economic crisis of the enterprises with
use of canonical catastrophe of a fold and assemblage
is offered. Mathematical models of development
of crisis at the enterprise at different levels of
detailed elaboration: 1) at an estimation of liquidity
and solvency, financial stability, business activity,
profitability; 2) at an estimation of the general financial
and economic condition of the enterprise; 3) for
construction of potential of development of enterprise
are offered
Article is devoted to the numerical analysis of regional problems for system of the equations of Nernst-Plank-Puasson (NPP), to application of these regional problems to modeling and studying of mass transfer in the channel desalting of electro dialysis device. Various mathematical models of the transfer of ions in potential static mode in the form of system of the quasilinear equations with private derivatives are offered. The basic rules of occurrence and development of a spatial charge in the channel desalting of electro dialysis device are revealed
In the article, the analysis of inconsistency of agricultural enterprise is carried out by various methods. The hypothesis about absence of a universal method of an estimation of the inconsistency, yielding authentic result is proved
This article analyzes the changes in the number of cases of various clients of the pyramid and the establishment of the basic rules of the pyramid schemes based on discrete models. The article is also a continuation of previous work [1], which had formulas to simulate the amount collected by the pyramid scheme
The article is devoted to the numerical solution of boundary value problem of the binaryelectrolyte model of transport in membrane systems in the approximation of Ohm's law. Different numerical methods are offered. The main regularities of transfer are established
This article analyzes the boundary problem model of transport of binary electrolyte membrane systems in the approximation of Ohm's law. Different methods of solution are proposed
In this article, a mathematical model of the dynamics of the efficiency of arbitration courts of Russian Federation in the form of the Cauchy problem for systems of difference and differential equations is built. The main regularities of the dynamics of the efficiency of arbitration courts are found
This article is a continuation of [1, 2] and is devoted to the description of a program complex "Region-Credit" for the assessment of financial stability, economic development, credit, socio-economic status and investment attractiveness of Russian regions. The article is an example of a comprehensive credit
analysis, socio-economic status and investment attractiveness of Krasnodar Region for the period from 2008 to 2014 with the help of a program complex "Region-Credit", whose results are compared with peer review rating agency AK&M
This article is devoted to the analysis of different cases of changing the number of customers of the financial pyramid and the establishment of the basic rules of the pyramid schemes on the basis of continuous models, and it is a continuation of works [1, 2], which had formulas to simulate the amount collected by the pyramid scheme and it considers the discrete models
In this article authors propose the asymptotic solution of the boundary value problem modeling the transport of salt ions in the cell electrodialysis desalination unit. The domain of the camera desalting broken into two subdomains: electroneutrality and space charge. Subdomains has own asymptotic expansion.
The subdomain of the space charge has unique solvability of the current approach used by the solvability condition of the next approximation
