OPTIMIZATION OF FLOW AND RHYTHM OF WORK OF THE HARVEST-TRANSPORT LINK

Using the optimization criterion for the minimum waiting time by hopper drives for loading their bodies with grain from combine harvesters working as part of a harvest transport link, a mathematical model of mutual coordination of work of combine harvesters and hopper drives has been developed. Optimized depending on the distance (field-threshing floor), the capacity of the bunkers of combines and storage drives, and their number in the link is interconnected taking into account grain yield. The work was performed with consideration of the cleaning process in the form of a system: "field - combine - vehicle - threshing floor". The connection between the subsystems, which determines the flow, the rhythm of the harvest-transport process and the effective functioning of the link machines, is established. The optimization criteria are derived from the parameters of the link machines and the distance from the field to the threshing floor, the cycle time of the drive from the distances of crossings and the capacity of the bunkers, the required number of drives for uninterrupted work of combines taking into account yield and distances from the field to the threshing floor. It has been established that with the help of modeling the harvest-transport process according to the optimization criterion mentioned above, there is a possibility of non-stop operation of combines and storage units (the mutual waiting time is zero). The software for modeling the work of the harvesting-transport link has been developed.
