Dynamics of changes in daily productivity of harvesting technological systems with transport support

The paper is devoted to the analysis of the daily productivity formation of the harvesting technological system with transport support for hay making, potato and grain harvest. It is established that the cumulative process of daily productivity is random. A linear model of the daily productivity of the system, based on a time-by-time examination of the working day is theoretically developed and experimentally confirmed. The general concepts of productivity are expanded due to the introduction of ideal, potential and final performance. Approximating dependences of daily productivity, which allow determining the actual productivity at any time of the working day, are obtained. The results of the research can be used to develop measures to improve the productivity of human-machine systems operating in agricultural technological processes.
