Abstract

This work considers a decision problem about orders of owners and routes for harvesters in an agricultural cooperative in which the di erent smallholdings of each owner should be processed as a block and each owner has a proposal about the instant in which he would like that a machine starts the activity in his land. Moreover, the cooperative has to administer a eet of trucks which have to pick up the forage gathered by a harvester and carry it to a silo. A binary linear programming model is introduced in order to bring down costs. Solving the model for actual size instances is computationally burdensome. Hence, we design and implement heuristic algorithms to reduce the computational time. The numerical results show that the heuristics can solve large instances with reasonable e ort.
