Abstract
This diploma thesis examines the optimization of logistics in corn harvest using Constraint Programming (CP). The most-widely method of harvesting corn involves forage harvesters and transport vehicles driving in parallel to each other on the field. The harvest in Germany is often carried out by contractors. Optimizing the distribution of a contractors' vehicles to fields in terms of harvest duration might reduce costs. The described harvest logistics process is modelled as a Multi-Mode Resource Constraint Project Scheduling Problem with Fast Tracking and Synchronization and solved using the specialized scheduling features of CP Optimizer. The results show the suitability of the CP-based approach for modelling the problem in terms of representability of its characteristics. A variety of test instances is solved, showing that large instances of the model need long computation times or cannot be solved to optimality within a time limit. Variants of the model are tested indicating promising improvements in computation time.
