Harmonization of project configuration of the crop harvesting technological system

The prerequisites for the development and use of methods and models to support decision-making in crop harvesting projects are revealed. The peculiarities of the project environment impact on the work timeliness in the technological harvesting projects development systems given. Emphasis is placed on the importance of timely execution of works in these projects, as well as the resolution of tasks related to coordination of their configuration (start time, scope of work, and technical equipment). The significance of the project environment impact (biological processes of sugar beet ripening and agrometeorological conditions) on the time constraints for the implementation of works in the projects is determined. It is shown that such an influence determines the variability of the terms of the start of work and their duration, and affects the functional indicators of work efficiency in harvesting projects. The need to take into account these features in the statistical simulation model of the technological system of harvesting projects has been proved. The results of using a statistical simulation model to evaluate the effectiveness and support of decision-making in these projects are presented. The methodology and results of considering the influence of the project environment (subject and agrometeorological conditions) on the terms and timeliness of work in harvesting projects are shown. The practicality of creating simulation models and the methodology of displaying the probabilistic conditions of functioning of the technical equipment of sugar beet harvesting projects are described. Computer experiments were performed with a simulation model with given initial data and technical equipment of the project (beet harvester SKS-624 “Palesse BS624-1” and tractor-trailer-loader HTZ- 243K.20+Hawe Ruw 2500T), crop variety and limits of its production square The peculiarities of the impact of the main components of crop harvesting projects on their efficiency indicators are revealed. The simulation was performed for the given limits of the production area of sugar beet - 10-300 hectares with a step-by-step increase of 20 hectares. Correlational dependencies of the functional indicators of the efficiency of the technological system at the time of the work started, the production area, and technical support of the projects, taking into account the probabilistic influence of the project environment, have been established.
