Simulation model for the sequential in-field machinery operations in a potato production system

摘要: A simulation model for the sequential potato operations was developed and validated.The can be implemented as an operation management tool production.Errors in prediction of field efficiency capacity were less than 4.8%, 6.1%, respectively. In production multiple have to carried out during yearly production, each may its own set operational features, given by used machinery. An optimal planning one lead restrictions reduced later operations. Therefore, there is a need develop approach predicting optimizing overall performance all operations, selected required machines. The work processes with corresponding decisions involved described using IDEF modelling MATLAB? programming software. Experiments relevant farming (bed forming, stone separation, planting, spraying harvesting) monitored four experimental fields quantify input parameters validate model. predicted (the ratio time machine effectively working total committed whole operation) area processed per unit time) satisfactory precision fields. errors ranged from 0.46% 4.84% 0.72% 6.06%, addition, capability management-planning decision support on (e.g. driving direction, reloading position) machinery dimensioning tank/hopper size) demonstrated.
