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
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
Relevance of developing Internet service for searching
travel companions for intercity and intracity trips
substantiated in the article. The existing services that
provide similar services were analyzed, their
shortcomings and advantages of the basic principles of
operation were identified and analyzed. Functional of
own service was disclosed in comparison to existing
ones. The variants to benefit drivers and passengers
were offered
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
In this article the size of material stream in bread-production chain with use of the theory of indistinct sets and application of risk component is predicted, the interval model of definition of efficiency is developed
