In assessing the optimal composition of machine and
tractor fleet nomenclature and quantitative composition
of parks of technical means and some parameters
of production technology are used as varying variables,
leaving the timing of mechanized fieldwork
fixed. At the same time, changing the duration of
mechanized operations in the most intense periods of
the field season can significantly affect the amount of
the basic means of mechanization as a part of machine
and tractor fleet, the value of investments in its formation.
The article used a method of determining the
composition of the machine and tractor fleet of agricultural
organizations considered the "flexible" duration
of the mechanized operations in field and based on
the iterative adjustment of the results of the optimization
of machine and tractor fleet by the criterion of the
minimum difference between savings investment and
value of crop losses. The analysis showed that the economically
viable term of harvesting of winter crops for
domestic combine harvester Acros-530 is a period of
16 days. The article analyzes the economic efficiency
of the different periods of the harvesting campaign
using imported agricultural machinery. This work presents
a sensitivity analysis of the effect of reducing the
need to combine at different periods of cleaning of grain crops to the level of prices for products and
equipments
In assessing the optimal composition of machine and tractor fleet nomenclature and quantitative composition of parks of technical means and some parameters of production technology are used as varying variables, leaving the timing of mechanized field work fixed. At the same time change the duration of mechanized operations in the most intense periods of the field season can significantly affect the amount of the basic means of mechanization as a part of machine and tractor fleet, the value of investments in its formation and operating costs. The article proposes a method of determining the composition of the machine and tractor fleet of agricultural organizations considered the "flexible" duration of the mechanized operations in field and based on the iterative adjustment of the results of the optimization of machine and tractor fleet by the criterion of the minimum difference between savings investment and value of crop losses. The realization of the algorithm described above will allow determining the optimal composition of machine and tractor fleet of agricultural organizations considering the possibility of changing the duration of mechanized operations in field in the most intense periods. At the same time the resulting calculations decision takes into account the compromise between the growth of production losses by increasing the duration of mechanized operations and a reduction in capital costs for the formation of the machine and tractor fleet
