GERT analysis of UAV transport technological cycles when used in precision agriculture

Abstract The article discusses a new stage in the development of the agricultural sphere, associated with the use of precision farming technologies. It is shown that the development of precision farming technology requires a higher level of technical support based on the use of unmanned aerial systems that perform differentiated application of pesticides and fertilizers according to a given field treatment program. A stochastic GERT-model of the UAV transport technological cycle is proposed. The loss of UAV performance over time serves as a criterion in the risk analysis of UAV transport technological cycles. This paper proposes a method for determining the quantitative characteristics of the risks of UAV transport units as a local criterion for the predicted amount of downtime and losses. A new method for calculating the quantitative values of the risk of UAV downtime, as the main link in the precision farming system in one transport technological cycle, is proposed based on the procedures of stochastic graphs.
