The article presents the results of the economic-mathematical modeling of the processes of evaluating the effectiveness of agricultural lending to small enterprises. It also describes the structure and the composition of the complex models and the numerical methods designed for this purpose
A modified version of the Solow model with endogenous technical progress is considered that exerts “explosive”, singular growth. A formula for the point of time of singularity is derived. The model is “upgraded” to a climate–economy model (an
Integrated Assessment model) describing the growth of the world economy under conditions of global climate change. A non-trivial stationary solution of the model is obtained. It is shown that this solution is unstable, and that the developed model manifests
“explosive growth” like the initial modification of the Solow model
This article discusses the ways of reducing the financial, economic and social risks on the basis of an accurate prediction. We study the importance of natural time series of winter wheat yield, minimum winter, winter-spring daily temperatures. The feature of the time series of this class is disobeying a normal distribution, there is no visible trend
This work is devoted to the methods of multicriteria optimization and classical statistics of obtaining pre-estimated information for time series that have long-term memory, which is why their levels do not satisfy the independence property, and therefore the classical prediction methods may be inadequate. The developed methods of obtaining such information are based on classical statistics methods such as mathematical statistics, multicriteria optimization and extreme value theory. The effectiveness of the proposed approach has been demonstrated on the example of specific time series of volumes of mountain rivers
ARTIFICIAL INTELLIGENCE METHODS FOR DECISION MAKING AND PREDICTING THE BEHAVIOR OF DYNAMICAL SYSTEMS
This article proposes a modification and training the Cellular Automaton predictive model. The author presents a modified system of models and methods for time series prediction with memory based on the theory of fuzzy sets and linear cellular automata
The article analyzes the transformation of the category "Income", it is clarified the modern meaning of this concept, taking into account industry characteristics of organizations engaged in the production of alcohol and alcoholic beverages
Effective functioning of small and medium business, its competitiveness, the implementation of the expanded reproduction is largely determined by the stability of its financial position. If small and medium enterprise financial stability and financial stability,
they successfully overcome unexpected changes in market conditions, and they are not facing bankruptcy. Financial sustainability of small and medium business - is it safe and secure solvency not only in the ordinary course of business, but also the random changes in the market
The article reviews existing theories of liquidity management, and the problems of liquidity simulation. Based on the example of the bank working in Samara the author created a model showing current liquidity of the bank and developed a forecasting and simulation model. This work presents shortcomings of the
existing models of the bank and offers specific optimization techniques through controlling variables. And also it provides a comparison of the liquidity assessing criteria under RAS and IFRS
The article deals with the question of economic efficiency of moldboard tillage using the developed combined ploughshare plow as a result of experimental studies, determining the degree of traction resistance of the reversible plow tillage combined with reversible plow. We have also found main economic indicators of the manufacturing operation and calculation of efficiency of investments for the implementation of the combined plow
This article discusses the basic tools of kaizen in the context of controlling and lean manufacturing as the elements of the system
