Methodical approaches to the formation of structural-parametric models of regulatory management of reproduction processes sustainability resistance in perennial agrocenoses

The necessity of forming structural-parametric models of normative management of the stability of reproductive processes in perennial agrocenoses is substantiated. Modern methods of managing the sustainability of reproductive processes in complex natural and man-made systems are considered: cognitive analysis and promising digital technologies. A structural model of the functional stability of reproductive processes in perennial agrocenoses has been developed, representing a hierarchical system that determines the structure of the relationships of functions and elements of reproductive processes, including the parameters of these relationships. An algorithm for the formation of a structural model of stability parameters has been developed, including the identification of functional areas of impacts; the formation of a system of evaluation indicators; the identification of functional ecological-economic and technological-economic relationships and the determination of their dimension; assessment of system-wide and functional stability of reproduction processes; determination of stability criteria and a system of restrictions; econometric modeling in order to determine the rational parameters of the stability of reproduction processes. The role of biotechnologies in ensuring the potential stability of agrocenoses, leveling the negative consequences as a result of climatic and chemical-man-made impacts on the elements of agrocenosis is substantiated. The tools of management of biotechnological processes in the elements of agrocenosis according to the criteria of adaptability, biologization and rational nature management are proposed. The normative-parametric model of ensuring the stability of reproductive processes has been developed, the main purpose of which is to substantiate the regulators (tools) of bringing the system to a stable state. The effectiveness of the adjustment of agrotechnological regulations in order to bring the indicators of the state of the agroecosystem to the normative level of stability is substantiated.
