Marielle Brunette et al., « Optimizing forest management under dependent price and production risks: a Markov decision process approach », Hyper Article en Ligne - Sciences de l'Homme et de la Société, ID : 10670/1.5zvos6
In the forest sector, natural disturbances have impact on production and prices. Traditionally, these risks have been analysed separately. In our model, the production risk translates into a price risk through a quality loss. We consider that the stock of timber follows a Markov Decision Process (MDP) with the harvesting decision as a control variable. We solve the optimal harvesting problem under storm risk with a risk-averse forest owner and when risk induces triple dependent consequences on production, price and timber quality. We study the impact of the risk distribution, the risk aversion level and the percentage of quality loss on the optimal harvesting decision.
