Field Operations Planning for Agricultural Vehicles:A Hierarchical Modeling Framework

摘要: The execution of field operations by a fleet cooperating machines needs to be carefully planned, in order achieve maximum efficiency. Hence, it is necessary describe these with mathematical models that can used for optimal planning. complexity agricultural makes such modeling difficult. Important variables planning, as logistics crop yield, cannot accurately known advance. Furthermore, unexpected events may happen during operations, harvester blockages and restarting operations. In this paper the overall planning problem decomposed into hierarchy simpler problems solved independently efficiently. Each lower-level modeled way optimization algorithms from research area adopted their solution. dynamic nature inherent uncertainties many parameters suggest adoption closed loop control system, which results sequence re-planning. resulting operation plans complex requires an advanced degree machine, or robot autonomy. Overall, modification existing methods other areas logistics, routing, factory scheduling, robotics offer very promising approach efficient executed vehicles.
