dc.description.abstract | Crop production entails many decision making processes aimed at improving productivity and
achieving the best yield from scarce resources. Assuming that there is a set of tasks to be
carried out within a given time horizon, and each task can be performed in different ways, the
problem consists of determining how and when to carry out each task, in such a way that the
tasks are scheduled in sequence at the minimum cost, taking into account any precedence
relationships among them, the time window constraints for performing the tasks and the
resources availability. This paper presents two alternative mathematical models to attain the
proposed objective. The first model splits the time into discrete units spread throughout the
planning horizon; it is presented in connection with flexible manufacturing. The second model
keeps a continuous time horizon; a scheduling model is used for which a family of {\it
incompatibility conditions} is introduced to avoid a certain type of simultaneous usage of
resources. This type of conditions require to introduce a new structure so-called conditional
disjunction. Computational experience is reported for real life problems. | es |
