    Technologies of supporting decision in understanding conditions for projecting technological processes
    (University of Engineering and Economics in Rzeszow, 2019-03-20) Brovarets, O. O.; Kovbasa, V. P.; Kyiv Cooperative Institute of Business and Law; Vinnytsia National Agrarian University
    Modern agriculture involves the implementation of a particular technological operation, according to the appropriate map-task, which is developed pre-based on diverse information. Knowledge of a certain structure of soil cover variability, obtained using information and technical systems of local operational monitoring of the agrobiological state of agricultural lands, allows us to adopt effective operational decisions for efficient managemen tagrobiological potential of agricultural lands. Obviously, under such conditions, there is a need for fundamentally new approaches to agricultural production, which is to ensure the proper quality of technological operations. The quality of the implementation of technological operations is an integral indicator of the efficiency of production of agricultural products within the agrobiological field. The necessary quality of implementation of the basic technological processes in plant growing is provided by the integrated information and technical systems of operational monitoring of the agrobiological state of agricultural lands. This opens new prospects for organic farming using such “smart” agricultural machines. In connection with this, the task is to obtain reliable data on the agrobiological state of the soil environment by reducing the error in determining the magnitude of the electrical conductive properties of the soil, providing individual stabilization of the working electrodes and the mechanism of lifting / lowering the working electrodes, copying inequalities of the soil environment, reducing the intensity of the destruction of the soil structure , self-cleaning of the working contact of the electrode and ensuring the stability of the electrical contact of the electrode with the soil, by instrument design perfection. The task is achieved by using the information and technical system of operational monitoring of the soil environment of the structure to determine the conductive characteristics of the soil environment. The purpose of this research is to determine the critical loading at the loss of stability by thin-walled working electrodes made in the form of working electrodes of various shapes (thinwalled solid, three-spit and four-spindle discs with different thickness of the rim). Information and technical system of local-operational monitoring of agrobiological state of soil environment of different configurations with one-side compression.

    Information technology of optimized agro-biological state management of agricultural lands
    (2019-06-26) Snytyuk, V.; Brovarets, O.; Taras Shevchenko Kyiv National University; Kyiv Cooperative Institute of Business and Law
    Available techniques for dealing with uncertainties in the agro-industrial complex and their use for describing and assessing the adequacy of the decisions taken are incomplete, and often ineffective, as they usually do not take into account the combination of “field-machinetechnological material”, which prevents acceptance effective solutions for managing agro-biological potential of agricultural land and, as a consequence, obtaining the maximum economic efficiency of agricultural production. Reliable estimation of variables of agricultural production parameters using the “field-machine-technological material” model makes it possible to provide optimal control of available technical equipment (machinery, sowing machines, etc.), agro-biological (humus content, presence of nutrients, micro-and macro elements, etc. in soil or plant ) and technological resources for making adequate decisions and managing agro-biological potential of agricultural lands, which will provide the necessary economic efficiency. The task is achieved by ensuring the proper quality of the implementation of technological operations that are an integral indicator of economic efficiency and allow providing the necessary economic efficiency through optimal and efficient management of technical means for optimal action on the agrobiological potential of the field and the use of available technological resources. Such control is possible with the use of information and technical systems of local operational monitoring, which are located on machine-tractor units and provide effective control of technological operations by acting on the executive bodies of agricultural machines on the basis of data characterizing the agro-biological state of the soil environment. Information and technical systems of local operational monitoring of the agro-biological state of agricultural lands are used in the following cases: – before performing a technological operation, – simultaneously with the implementation of the technological operation (sowing, fertilizer application, etc.), – during the growing season and after harvesting. This opens new prospects for organic farming using such “smart” agricultural machines.
