The obtained assessment of the efficiency of a given activity has concrete purposefulness and is very sensitive to the change of both external and internal environmental disturbances. The random parameters of natural climatic environmental conditions, organization and structure of the farm and random values of the parameters of the used aggregates presuppose a complex assessment to determine the extent of effect of the different factors. The objective of this work was to suggest a methodical approach and to justify a formalized relation between the parameters of grapevine plantations and the technological complex of machines and the conditions of their cultivation.
A methodical approach and a well-founded formalized relation between the parameters of the grapevine plantations and the technological complex of machines and the conditions of their cultivation are suggested. Relations are suggested for determining the productivity during basic technological operations, their material provision, costs of FLM and transport. It was found that the sensitivity of the variable costs decreased over 32 ha. A criterion of assessment of the extent of effect of the factors influencing the costs in wine grape growing is suggested on this basis.
