Description
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

01.00.00 Physical-mathematical sciences
DescriptionArticle 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

MATHEMATICAL MODELING OF FINANCIAL PYRAMID SCHEME. PART 2. DISCRETE MODELS
01.00.00 Physical-mathematical sciences
DescriptionThis 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

SOFTWARE TOOLS TO ANALYZE THE REGION'S CREDITWORTHINESS
DescriptionThis 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

THE HIGHER ASYMPTOTIC EXPANSIONS FINDING FOR BOUNDARY VALUE PROBLEM OF THE ZOM MODEL
01.00.00 Physical-mathematical sciences
DescriptionIn 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
