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

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 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

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 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

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

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 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

The models of the estimation advertising effectiveness are reviewed and analyzed in the paper. The algorithm and example of the program’s work, which determines financial performance of the company with taking into account advertising investments is described and the mostly important results are discussed

The results of cluster analysis of the operational functioning of the Russian arbitration courts of various instances are shown, and the new mathematical model of discriminant analysis to measure the efficiency of arbitration courts are presented
