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
The article deals with the results of research of acoustic and magnetic field influence on conductivity and pH value of hydroponic solution. For carrying out researches in this area the hypothesis of possibility of nutrient solution influence on ions by means of an acoustic and magnetic field is set up. A laboratory scale plant was constructed for a pilot study of the hypothesis. The solution was moved in the tube passing through a ferrite ring with winding. Thus, the solution was exposed to the influence of acoustic and magnetic field. The object of research was hydroponic solution of (NH4)2SO4; (NH4)2HPO4; K2SO4; Ca(NO3)2; MgSO4 in water having adjusted concentration and acidity. The solution was taken from the tank of laboratory scale plant by means of the pump, passed through the working area of the acoustic and magnetic device, filter, and then was poured into the tank, from which the sample for pH level changing was taken. The pH value was measured at the temperature of 22С by using electronic pH-meter KL-009(1)A. For control of instrument readings acidity was tested by universal test-paper. The initial pH value of solution made 5. As a result of acoustic and magnetic treatment of solution pH value of hydroponic solution increased from 6 to 6.9. The results show the possibility of pH value correction by small energy input
In this article we have presented the results of the
research of submission and evaluation of organizational structures of control systems based on the theory of mass service
The article presents the results of further research of a streaming scheme of interaction between agricultural (AGC) and processing (PP) agricultural enterprises. Mathematical models were developed and the results were shown for a quantitative comparative evaluation of the efficiencies of the combined company (AGC + PP) and processing (PP) agricultural companies
One of the most popular methodologies of credit indebtedness management is used by banks, financial institutions and the collection agency has been considered in this article based on the experiment. This experiment demonstrates the methods of
estimations of the client’s solvency and the way to impact to debitors. The article is accompanied with explanations and
conclusion
In this article, the problem of short-range forecasting of value and dynamics of economical indexes of diversified corporation is stated, on the basis of application of systemic-cognitive analysis and its tooling (intellectual system "Eidos") the formal problem definition and data domain formalization, i.e. development of classification and descriptive dials and graduations and shaping of training sample is performed
The article describes the fuzzy-multiple approach and the block of fuzzy (interval) mathematical models developed by the authors for calculating the amounts of material and financial flows, prices for bread and economic efficiency in a technologically integrated bread production system
The models that quantify the investment efficiency of horizontal and technologically (vertically) integrated systems, as well as agro-industrial group that include both the technological verticals of recycling enterprises and the horizontal integration of agribusinesses companies are presented
The modern approach for the assessment the client's solvency for loaning is considered in the article.This approach explains the use of scoring models to optimize the decision-making process for the loan request. The approach to systematize the credit scoring with descriptions of new methods, models and toolkits making it possible to increase opportunities of the assessment and analysis is recommended with the experiment is recommended
In the article, we proposed the fundamental mathematical support of the state investment management of the agricultural production at the regional level, the content of which is determined by the next run of the development: the structure of the investment mechanism of farm management, hierarchy and relationship models and stages of the investment management of agricultural production; models preliminary comparative evaluation of agricultural enterprises - participants of the investment process, models and algorithms investment and resource optimization of the industrial structure of agricultural enterprises; models final selection of participants implementation of public investment programs and the distribution of funds
