| 1 | Coupling of crop assignment and vehicle routing for harvest planning in agriculture显示文摘A method for harvest planning based on the coupling of crop assignment with vehicle routing is presented.Given a setting with multiple fields,a path network connecting these,multiple depots at which a number of harvesters are initially located,the main question addressed is:Which crop out of a set of different crops to assign to each field when accounting for the given setting?It must be answered by every farm manager at the beginning of every work-cycle starting with plant seeding and ending with harvesting.Rather than solving an assignment problem only,it is here also accounted for the connectivity between fields.In practice,fields are often located distant apart.Traveling costs of machinery and limited harvesting windows demand optimized operation and route planning.Therefore,the proposed method outputs crop assignments to fields and simultaneously determines crop-tours,i.e.,optimized sequences in which to service fields of the same crop during harvest.It is of particular relevance for larger farms and groups of farms that collaborate and share machinery.Integer programming based exact algorithms are derived.For large numbers of fields,where these algorithms may not be tractable due to computational constraints,elements of clustering and the solution of local Traveling Salesman Problems are added,thereby on the one hand rendering the method heuristic and in general suboptimal,but on the other hand maintaining large-scale applicability. | Mogens Graf Plessen | 2019 | Artificial Intelligence in Agriculture2019，，2： | 3 |
| 2 | Freeform path fitting for the minimisation of the number of transitions between headland path and interior lanes within agricultural fields显示文摘Within the context of in-field path planning this paper discusses freeformpath fitting for theminimisation of the number of transitions between headland path and interior laneswithin agricultural fields.This topic ismotivated by two observations.Due to crossings of tyre traces such transitions in practice often cause an increase of compacted area.Furthermore,for very tight angles between headland path and interior lanes undesired hairpin turnsmay becomenecessary due to the limited agility of in-field operating tractors.Byminimising the number of interior lanes both detrimental effects can be mitigated.The potential of minimising the number of interior lanes by freeform path fitting is evaluated on 10 non-convex real-world fields including obstacle areas,and compared to the more common technique of fitting straight interior lanes. | Mogens Graf Plessen | 2021 | Artificial Intelligence in Agriculture2021，，1： | 0 |
