摘要：An information system (IS) for analyzing, assessing risks and their
impact on the economic activity of agribusiness in Ukraine is developed.
The Global Administrative Risk Management System can
use this information system or its parts as a component. A new
method for designing IS for risk analysis and assessment in the
sphere of agriculture is suggested. An original mathematical model
of such an IP is used. This mathematical model is specifically designed
to reduce the IS resources’ expenditures. A significant reduction
in the volume of calculations per unit of time has made it
possible to significantly simplify IS and to reduce the price of hardware
and standard IS software. This makes the information system
an affordable budget option for information support of small and
medium-sized agricultural enterprises in Ukraine. To create a risk
management model, it is suggested to separate the system of
management and decision making and the system of risk monitoring.
These two systems have different tasks and are implemented
by fundamentally different mathematical algorithms. The risks of
most agricultural projects have a high degree of uncertainty. Therefore,
even the composition of the risks’ set is dynamic. All possible
risks are suggested to be passed through the monitoring procedure.
To do this, a separate software unit with an autonomous
security system should be used. Models of the codomain of risk
change are presented where the specified region is a nonstationary
scalar or vector field. An improved scheme of designing
AIS for analysis and risk assessment in agriculture was suggested,
which allowed significantly reducing the IS resources expenditures.
Significant decrease in the volume of calculations per unit of time allowed significantly simplifying and cheapening the hardware part
of the AIS. This made the use of AIS an affordable budget option for
the information support for small and medium-sized farms in
Ukraine. The developed AIS for the risks analysis and assessment
and of their impact on the economic activity of the agro-enterprise
was tested in Odessa and Mykolaiv regions.
