Salgado Rojas, José; Álvarez Miranda, Eduardo; Hermoso, Virgilio; García-Gonzalo, Jordi; Weintraub Pohorille, Andrés (Elsevier, 2020)Planning for management actions that address threats to biodiversity is important for securing its long term persistence. However, systematic conservation planning (SCP) has traditionally overlooked this aspect and just ...

Álvarez Miranda, Eduardo; Garcia-Gonzalo, Jordi; Ulloa-Fierro, Felipe; Weintraub Pohorille, Andrés; Barreiro, Susana (Elsevier B.V., 2018)We propose a multicriteria decision-making framework to support strategic decisions in forest management, taking into account uncertainty due to climate change and sustainability goals. In our setting, uncertainty is ...

Álvarez Miranda, Eduardo; Garcia-Gonzalo, Jordi; Pais, Cristobal; Weintraub Pohorille, Andrés (Elsevier B.V., 2019)© 2018 Elsevier B.V.A core process in forestry planning corresponds to the design of optimal harvesting policies along with road network layouts. In the most common setting, decision makers seek for solutions that maximize ...

Bagaram, Martin B.; Toth, Sandor F.; Jaross, Weikko S.; Weintraub Pohorille, Andrés (Hindawi, 2020)Long time horizons, typical of forest management, make planning more difficult due to added exposure to climate uncertainty. Current methods for stochastic programming limit the incorporation of climate uncertainty in ...

García Gonzalo, Jordi; País Martínez, Cristóbal; Bachmatiuk, Joanna; Barreiro, Susana; Weintraub Pohorille, Andrés (MDPI, 2020)Due to the long time horizon typically characterizing forest planning, uncertainty plays an important role when developing forest management plans. Especially important is the uncertainty related to recently human-induced ...

Basso, Franco; D'Amours, Sophie; Rönnqvist, Mikael; Weintraub Pohorille, Andrés (Blackwell Publishing Ltd, 2019)© 2018 The Authors. International Transactions in Operational Research © 2018 International Federation of Operational Research Societies During recent years, horizontal collaboration in logistics has gained attention because ...

García Gonzalo, Jordi; Pais, Cristóbal; Bachmatiuk, Joanna; Weintraub Pohorille, Andrés (Canadian Science, 2016)An approach is proposed for incorporating the variations in timber growth and yield due to climate change uncertainty into the forest harvesting decision process. A range of possible climate scenarios are transformed by a ...

Accounting for cost heterogeneity on the demand in the context of a technician dispatching problem Cavada, Juan P.; Cortés Carrillo, Cristián; Goic Figueroa, Marcel; Weintraub Pohorille, Andrés; Zambrano, Juan I. (Elsevier, 2020)In the technician dispatching problem, a given number of repair teams must visit different locations to provide service support. Considering that there is a fixed vehicle capacity and variations in the demand, not all ...

Álvarez Miranda, Eduardo; Salgado Rojas, Jose; Hermoso, Virgilio; García-Gonzalo, Jordi; Weintraub Pohorille, Andrés (Elsevier, 2020)The design of conservation management plans is a crucial task for ensuring the preservation of ecosys- tems. A conservation plan is typically embodied by two types of decisions: in which areas of a given territory it will ...

Rios Uribe, Ignacio; Weintraub Pohorille, Andrés; Wets, Roger (Routledge, 2016)We analyse how to deal with the uncertainty before solving a stochastic optimization problem and we apply it to a forestry management problem. In particular, we start from historical data to build a stochastic process for ...

Alonso-Ayuso, Antonio; Escudero, Laureano F.; Guignard, Monique; Weintraub Pohorille, Andrés (Elsevier, 2020)A new scheme for dealing with the uncertainty in the scenario trees is considered in the presence of strategic and tactical stochastic parameters for a dynamic mixed 0-1 optimization model in a forest harvesting network ...

Epstein Numhauser, Rafael; Goic Figueroa, Marcel; Weintraub Pohorille, Andrés; Catalán, Jaime; Santibáñez, Pablo; Urrutia, Rodolfo; Cancino, Raúl; Gaete, Sergio; Aguayo, Augusto; Caro Valdés, Felipe (2012-02)We present a methodology for long-term mine planning based on a general capacitated multicommodity network flow formulation. It considers underground and open-pit ore deposits sharing multiple downstream processing plants ...

Alonso Ayuso, Antonio; Escudero, Laureano F.; Guignard, Monique; Weintraub Pohorille, Andrés (Elsevier, 2018)The paper presents and compares approaches for controlling forest companies' risk associated with advance planning under variable future timber prices and demand. Decisions to be made in advance are which stands to cut and ...
