The article discusses the use of a graphic-analytical method for evaluating and revising plans for GERT-network modeling of transport and technological cycles of unmanned aerial vehicles utilized in the precision farming system. A formal description of the model and an algorithm for searching for the optimal implementation of the UAV transport and technological cycle are proposed, which allows minimizing the costs of its implementation taking into account the characteristics of production situations that arise in the precision farming system when using the UAV. The formalization method is based on the notion of the UAV transport and technological cycle as an acyclic GERT network with a source and sinks. Since the stochastic dynamic structure of the transport-technological cycle is considered, the possibility of introducing random events during its implementation and the execution of several successive cycles is provided. At the same time, the minimum possible costs when performing these transport and technological cycles must satisfy the optimality criterion. It is suggested to switch to cost reduction by means of an iterative procedure at the optimization stage taking into account the finite number of UAV transport and technological cycle implementation stages. As a result, the decision maker, employing the decision GERT network, will be able to choose the implementation of the transport and technological cycle that minimizes costs for its implementation. The paper proposes an algorithmic procedure that ensures the choice of the best possible solution, which helps to increase the efficiency of formation, analysis and management of UAV transport and technological cycles, as it enables full consideration of the characteristics of production situations in precision farming systems using unmanned aerial vehicles.
