The analysis and assessment of risk at the macrolevel
in this context is understood as assessment of extent
of influence of the external environment (macro
environment) on activity of the integrated production
system. In the article the model and the technique of
calculation of an integrated indicator of risk of an
adverse effect of the external environment of the
agro-industrial integrated production system is
offered. All stages of creation of the model which
include representation of basic risk factors of
macrolevel in the form of linguistic variables are
described, each of basic risk factors is a compound
linguistic variable. For obtaining total value of a
basic factor the matrix scheme of aggregation of
compound factors to basic level is used. The
equation of model of an integrated indicator of risk
of an adverse effect of the external environment on
the integrated production system is presented. The
principle of recognition and interpretation of result
on the basis of standard fuzzy 01-classificators is
shown. Also in this article the interrelation of an
integrated indicator with the choice of the strategy of
development for business system by definition of a
condition of the external environment is shown, and
depending on it the strategic scenario of development
of business system is offered
Production and processing of grains formed in the national economic system of the country a number of cereals-governmental sectors, such as grain production, grain elevator industry, flour, cereals and mixed fodder production, which constitute the grain complex country. The significance and role of the grain as a commodity in the state economy can not be overestimated. This product, is totally liquid, which has a constant, steady demand at any time of the year, in any region. Ongoing measures to increase grain production and improve its implementation did not have a complex character, therefore, insignificant effect on the efficiency of the industry and the competitiveness of grain production. The shortagecovered by imports.According to the characteristics of management in agriculture, it should be emphasized that the absence of objective and timely information at all stages of production of the plant-breeding, and as a result, non-optimal choice of technology of cultivation of agricultural crops, might result in the fact that the cost of labor and material resources increases significantly, the company does not receive profits, and sometimes suffers losses. When selecting cultivation technology for agricultural crops, an agronomist has a database of more than a hundred times-personal of alternative technologies for each crop. It is up to the decision-maker (DMP) to find specific criteria to select the most suitable (for the owners and the climatic zone) technology of cultivating for the culture. These circumstances explain the relevance of in-depth research of economic and mathematical models and methods of analysis and evaluation of the economic efficiency of technologies of cultivation agricultural crops. The article deals with the process of developing multicriteria economic-mathematical model of a comprehensive assessment of technology of cultivation of agricultural crops.
In this article the model and a calculation procedure of
an integrated indicator of risk of the internal
environment of the integrated production system are
described. Then the steps of creation of triangular
fuzzy number for expected value of profit are given.
At creation of this fuzzy number the concept of an
indicator of risk of the internal environment of the
integrated production system was used. Further on the
basis of the developed model of internal risk the
interval model of efficiency of the integrated
production system is developed and described. In this
article the structure of a production chain of the
integrated production system of agroindustrial
complex was considered. In technologically complete
production chain, as a rule, allocate three stages – raw
materials production, storage and conversion, sale of
finished goods. Each subsequent stage depends from
previous stage, and at each stage various situations of
risk are shown. Also the process of risk identification
of the internal environment of the integrated
production system was considered in this article.
Process decomposition is executed, the description of subprocesses is given. For a risk assessment of the
internal environment it is necessary to know quantity
of production chains, and also to calculate value of risk
for each production chain on the enclosed algorithm.
Also in the article the principle of recognition and
interpretation of results of calculation of an integrated
indicator of risk of the internal environment of the
agro-industrial integrated production system on the
basis of Harrington's scale and standard indistinct 01
classificators is shown
In this article, the general structure of technologically
complete production chain of the integrated production
system of agroindustrial complex was considered.
Three different variants of creation of the production
chains are described. The main distinctions in activity
of chains consist in a source of raw materials. Any
technologically full vertical chain includes three stages
– production of raw materials, storage and processing,
realization. Each of stages is characterized by different
situations of the risk. Stages of process of functioning
of a production chain were considered in this article.
Also, the qualitative analysis of risk for all stages is
made and the results of this analysis are considered.
Results of this analysis became a basis for
improvement of stream model for determination of
efficiency of the technological chain taking into
account a risk component. In the article, the algorithm
of an assessment of efficiency of the technological
chain of the integrated production system taking into
account a risk component at the stage of creation of a
material stream is also described
The article analyzes reasons that prevent the formation of stable and effective AIC associations of commodity businesses and processors of raw materials. Unbalanced process of the relationship between agricultural producers and processing plants have a negative impact on the economic situation of the organizations partners. Dictating low purchasing prices for raw materials by processing enterprises hinders profitability of agricultural producers. Purchase prices set by the processing enterprises of the dairy industry for milk, do not compensate for not only the production costs but also the losses from inflation. The rate of growth in energy prices is significantly higher than for livestock products, bringing its cost grew faster than sales prices. This leads to a dramatic reduction in milk production profitability. A paradoxical situation: on the one hand, dairies are facing an acute shortage of raw materials, on the other - exacerbated the problem of the sale of its milk producers at a reasonable price for them. The disparity between the purchasing prices for milk and retail prices for dairy products caused agricultural companies to seek alternative markets. Sharply increased sales of milk in the bottling of milk tankers, while many farms began to create their own recycling system
In the article we have reflected a relationship between
the parameters of the research activities of scientific
and pedagogical collectives and the characteristics of
the educational environment in higher education. It is
known that the research activities of scientific and
pedagogical workers and teams - an integral part
functioning of the higher education institution (and
improving its efficiency is one of the most important
problems). The authors proved that parameters
reflecting research activity of scientific and
pedagogical higher education of institution employees
characterize the aspects of the educational
environment as its latitude, intensity, social activity,
coherence, mobility, stability, reliability and
efficiency. It is caused by the fact that the research
activities of scientific and pedagogical workers - a
multifaceted social and cultural phenomenon. The idea
of the diagnosis of the educational environment of a higher educational institution and its structural units,
based on an assessment of scientometric indicators
(criteria for research productivity), can be completely
suitable for international and Russian requirements:
the well-known Shanghai procedure shifts the
emphasis on the evaluation of various aspects of the
research activities in higher education; serious
attention to assessing the research activity focuses and
Russian technique diagnostic efficiency of higher
education institutions. This is logical and soundly: if
the educational environment of a higher educational
institution is not a center of science, then it cannot
have effectively and competitive graduates, because
Research and pedagogical staff - the governing factor
in the educational process. Based on previously
developed models of research activities in scientific
and pedagogical collectives, as well as on generally
accepted models of educational environments, the
authors have proposed a method for the diagnosis of
the educational environment, based on an assessment
of scientometric indicators - parameters reflecting the
impact of the research activities of scientific and
pedagogical workers. Obtained results may be the
theoretical basis for further scientific understanding of
the problem of increasing the productivity of research
activities in higher education, as well as problems -
increasing the competitiveness of educational
environments. The practical significance of the results
of this study - the possibility of their use in the system
of socio-pedagogical monitoring - monitoring of
productivity the research activities and effectiveness of
educational environments. Methods of investigation:
modeling, methods of the theory of sets and relations,
methods of probability theory and mathematical
statistics, methods of the theory of limits, methods of
linear algebra and analytic geometry, multi-parameter
analysis of the systems and methods of quality control
(latent variables theory). Methodological bases of
research: a systematic, metasystem, qualimetric,
sociological and probabilistic and statistical
approaches
Conditions in which the work of acoustic magnetic device
proceeds are complicated because of the number of
interconnections. Solving problems under such conditions
analytically is difficult because of many variables
and complexity of some dependencies. The article describes
the conditions in which the work of acoustic
magnetic device, designed for nonchemical treatment of
hydroponic solution, takes place. The criteria, establishing
the initial state of the chains, containing mutual inductance,
are analyzed. The work establishes the criteria
relating the physical parameters of the environment with
the output parameters of the device. The similarity of
conditions of heat transfer on the surface of the device is
provided, and the relation of the scale of temperature
and power lost when heating the ferrite and winding
machine is determined. The criterion of the heat transfer
process is defined. The criterion, determining the relation
of the environment temperature to the thermal
mode of the acoustic magnetic device, is defined. The
criterion of the conditions at the boundaries of the
system and cavitating liquid is determined. It is found,
that the cavitation area appears in the technological volume
of liquid at the work of acoustic magnetic device.
The criterial equation for geometric parameters of different
types and constructions of the acoustic magnetic device is defined. In accordance with the task based on
the third theorem of similarity, the group of criteria that
provides the similarity of the model to the proposed
original by all existing indicators, is selected
The article compares various hypotheses that explain the mechanisms of the influence of the magnetic field with different characteristics on liquids, physico-chemical and biological systems. Physical effects that cause specific biological activity of water (magnetic treatment of water, production of thawed water, degassing, etc.) make water be metastable or non-equilibrium states. Water attracts the attention of researchers as a likely universal mediator in the transmission of electromagnetic field signals to the biological level. Water is involved in a variety of chemical and metabolic reactions, so the question about the ability to change the properties of water and solutions under the influence of fields of different nature: an electromagnetic field with different frequencies, with different combinations of field orientations (parallel constant and variable magnetic field, slope fields, rotating magnetic fields, magnetic fields close to zero and electric fields) arises. At the heart of existing methods for treating liquids lie methods that use the energy of the acoustic and magnetic fields, as well as complex methods of influencing the electromagnetic field in combination with thermal heating, pressure change, etc. The analysis of existing hypotheses about the mechanisms of the influences of fields of a different nature on the treated liquid makes it possible to put forward a hypothesis about the possibility of the joint influence of the acoustic and magnetic fields on the liquid by means of the acoustic and magnetic device
The integration of producers of raw materials and its processors into the agro-industrial complex is connected with the social division of labor, its specialization, the need for interaction between specialized branches and types of agro-industrial production. Agrarian enterprises are united in an effort to reduce the risk, the emergence of which depends on the climatic conditions, the spontaneity of the agricultural market, the dictates of processing enterprises, the need to increase the competitiveness of production. In the Russian practice, there were various organizational forms of integration, differing in the nature of economic ties between participants, the degree of independence of the enterprises entering the association, the combination of centralization and decentralization of management. Conventionally they are divided into associative - "soft" and corporate - "hard." The "soft" forms of association include as-association, union, non-profit partnership and strategic alliance. They can effectively function at the interregional level. A rigid type of integration ties is characteristic for combines, concerns, trusts, holdings. Agricultural consumer cooperatives are voluntary associations of legal entities and individuals residing or operating in a certain rural area on the basis of membership and pooling of money units in order to meet the needs of members in credit resources and other banks services. The conditions for the emergence of sustainable integrated associations in the agroindustrial complex require qualitative and quantitative analysis based on mathematical modeling
To increase the validity of conclusions about the impact of environment on quality of life we need to move from generalities to the application of quantitative modeling techniques. This requires the joint processing environmental databases and databases depicting various aspects of quality of life. These databases need to be handled not just together, but in a comparable form approach, technology and methodology; and we need to implement them in one software system. For the first time in the environmental studies it has been planned to be done with the application of the ASK- analysis and the system called "Eidos". In this work, we set the goals and the objectives of the application of the ASK-analysis to study the effect of environmental factors on the quality of life of the population of the region. The article reveals the urgency of this study; the requirements for the method of conducting the study, the choice of research method, the contents of the objectives of the study. The proposed work is at the edge of mathematical ecology and mathematical modeling of quality of life (which refers to mathematical and instrumental methods of Economics), resulting from expected synergies, consists in obtaining of new knowledge in these fields, that is relevant to both ecology and economy. This knowledge will make it more meaningful and justified for the application of environmental criteria and concepts in the economy
