Abstract
The article covers the systematic basis for the
creation of new technological processes of corn harvesting
machines. Modern corn-harvesting machines have
reached certain thresholds according to their technological
properties that most significantly affect the final production
and economic indicators of planting corn for grain
efficiency, still they do not meet modern requirements.
The technological properties mentioned above are hardly
adjusted for wide range of physical and mechanical properties
of the plants and crop parameters.
This situation is caused by new machine´s working
parts being viewed by researchers and developers as complex
technical systems not from the standpoint of general
systems theory but in terms of the use of traditional
knowledge of the laws of agricultural mechanics, thus not
getting proper attention to their systematic coordination
with working conditions.
Based on this, the paper presents a structural scheme
for the system “mechanized corn for grain harvesting”,
key elements of which are: agricultural (А), engineering
(В) and selectional (С) supply. Interconnection of the
subsystem´s elements and their consistency determine the
effectiveness of the whole process. Inconsistency of the
links АВ and ВC is observed. The conceptual system
“mechanized corn for grain harvesting” design relates
to the field with clear NO-factors: incompleteness, uncertainty,
inconsistency and lack of information for decision
making, thus it is important to review tasks of conceptual
design from the most general constructual standpoint. The
method of describing systems at the conceptual level is
suggested.
This systematic representation of corn-harvesting
machines allows to approach the task of their workflows
modeling from the most general standpoint.
