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 describes the process of developing the
two-level technique for assessment of the missed
benefit during the landing and cultivation of perennial
plantings. The technique is developed for the
enterprises where the cycle of production of raw
materials breaks into several periods until the first
harvest. The choice problem of the most suitable
grades for the landing is relevant for such enterprises.
The first level of the two-level technique assumes
assessment of qualitative and quantitative
characteristics of grades with use of such tools as the
theory of fuzzy sets and the decisions tree. The results
of the first level are entrance data for the second level
where there is final assessment of a grade and
determination of the missed benefit rather potentially
possible at the choice of the recommended grade. In
the article also designated the importance of the raw
materials stage for the technological chain. It is shown
that, being consecutive structure, the technological
chain strongly depends on the first stage – a stage of
raw materials production. Minimization of the risk
situations at the first stage promotes strengthening of
the general risk tolerance of a technological chain
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
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 the article the results of research of efficiency of three types of bread producing production associa-tions of consumers' co-operative society with vertic-al integration and models of optimization of their entrance parameters are resulted
The performance indicators of a trading company in
physical and monetary terms is significantly affected
by the types and volumes of purchased and sold
products, and which she purchased suppliers and the
consumers sold. However, the solution to the problem
of choosing the rational range of products faces
considerable cost of computational and human
resources, and lack of baseline data, and in real
dimensions this problem has no solution. The paper
proposes such a solution is very economical in costs of
different types of resources based on the application of
information theory, cognitive and control theory
Management problem of agro industrial holding is formulated in the article in general, from one hand, it is necessary to work out recommendations and adaptive model on holding management for it, and from other hand, designing of its model is difficult because of high complexity and dynamics of inner logistics of an management object, its territorially distributed and multi branch character, large amount of economic indexes, characterizing its activity on different levels of its organization. General method of formulated problem decision by means of systemic-cognitive approach is offered. First stage of model synthesis is described: cognitive structure formation of private models, entering its multi-level semantic information model.
Methodology of using systemic cognitive analysis for building multi-level semantic information model of agro-industrial holding management is formulated in the article in general. Based on this, solutions of forecasting problems and support of decision-making process of management and scientific researches are listed
In this article, in accordance with the methodology of
the Automated system-cognitive analysis (ASCanalysis),
we examine the implementation of the 3rd
ASC-analysis: synthesis and verification of forecasting
models of development of diversified agro-industrial
corporations. In this step, we have synthesis and verification
of 3 statistical and 7 system-cognitive models:
ABS – matrix of the absolute frequencies, PRC1 and
PRC2 – matrix of the conditional and unconditional
distributions, INF1 and INF2 private criterion: the
amount of knowledge based on A. Kharkevich, INF3 –
private criterion: the Chi-square test: difference between
the actual and the theoretically expected absolute
frequencies INF4 and INF5 – private criterion:
ROI - Return On Investment, INF6 and INF7 – private
criterion: the difference between conditional and unconditional
probability (coefficient of relationship).
The reliability of the created models was assessed in
accordance with the proposed metric is similar to the
known F-test, but does not involve the performance of
normal distribution, linearity of the object modeling,
the independence and additivity acting factors. The
accuracy of the obtained models was high enough to resolve the subsequent problems of identification,
forecasting and decision making, as well as studies of
the modeled object by studying its model, scheduled
for consideration in future articles
In this article, in accordance with the methodology of
the Automated system-cognitive analysis (ASCanalysis),
we examine the implementation of the 1st
and 2nd stages of ASC-analysis: cognitive structuring
and formalization of the subject area. At the stage of
cognitive structurization of subject area, researchers
decide what to consider as the object of modeling, the
factors affecting it and the results of their actions. In
accordance with the results of the cognitive structurization,
we prepare the initial database for the study
(training sample or case-based reasoning). At the stage
of formalization of the subject area, the base of the
original data is being normalized, i.e., we develop
classification and description: the scale and graduations
and with their use the base of the source data is
being encoded. The result is a database of events
(eventological database) and the training sample. The
stage of cognitive structuring and preparation of the
source data is not formalized and the formalization of
the subject area is fully automated and performed directly
with the use of the universal cognitive analytical
system named "Eidos", which is a software Toolkit for ASC-analysis. Stages of cognitive structurization and
formalization of the subject area of ASC-analysis are
the first steps of data conversion into information and
into knowledge. Subsequent steps: the synthesis and
verification of system-cognitive model, the decision of
problems of identification, forecasting and decision
making, as well as studies of the modeled object by
studying its model will be considered in future articles
