Abstract
This thesis addresses a timber harvest scheduling problem in Eucalyptus globulus Labill. plantations in Galicia (northwestern Spain) intended for the production of cellulose pulp under the sustainable forest management paradigm. To this end, a novel approach to attain the so-called sustained timber yield is developed first by means of an integer linear programming model. Then, the mathematical model is extended to include the objective of erosion control as well as several sustainability indicators. To consider erosion control, a new concept based on hydrological connectivity and termed hydrological adjacency is developed. Finally, different management alternatives are generated and ranked according to their overall sustainability by iteratively solving an extended goal programming model.
