Forest planning at the landscape level has the potential to become a large intractable problem. In Finland, Metsähallitus (the state enterprise that manages federally owned land) creates strategic plans to determine the appropriate harvest level. While these plans are feasible, they are not implementable in practice as the harvests are scattered temporally and spatially. Requiring that harvests be organized both temporally and spatially for practical implementation can result in an intractable problem. Through a hierarchical approach, the problem can be organized into steps in which the intractable problem is broken down into smaller easily solvable parts. As an approximation technique, the hierarchical approach may not find a solution close to optimality. To meet this challenge, we combine the top hierarchical level problems with a limited selection of lower hierarchical level problems into a single optimization problem. An iterative process is then used to improve the link between the hierarchical levels. We evaluate the landscape-level management plans developed by the iterative approach with a solution to the complete problem. The iterative process dramatically improves the strategic solution, performing near the global optimum. This suggests that the process can be applied to more computationally challenging problems such as spatial planning and stochastic programming.

On stochastic modelling and reliability of systems with moving cracked material
Tirronen, Maria (University of Jyväskylä, 2015)In many industrial processes, such as printing paper, a material travels through a series of rollers unsupported and under longitudinal tension. The value of the tension has an important role in the system behaviour, ... -
Interactive decision support and trade-off analysis for sustainable forest landscape planning under deep uncertainty
Shavazipour, Babooshka; Podkopaev, Dmitry; Miettinen, Kaisa (Canadian Science Publishing, 2022)Sustainable environmental management often involves long-term time horizons, multiple conflicting objectives, and by nature, is affected by different sources of uncertainty. Many sources of uncertainty, such as climate ... -
Economics of mixed-species forestry with ecosystem services
Tahvonen, Olli; Rämö, Janne; Mönkkönen, Mikko (Canadian Science Publishing, 2019)The Faustmann-Hartman setup is widely established for specifying the economics of forest values besides timber, but it is criticized as restrictive for capturing diversity values. We show that extending the model to cover ... -
Optimizing management to enhance multifunctionality in a boreal forest landscape
Triviño, María; Pohjanmies, Tähti; Mazziotta, Adriano; Juutinen, Artti; Podkopaev, Dmitry; Le tortorec, Eric; Mönkkönen, Mikko (Wiley-Blackwell Publishing Ltd.; British Ecological Society, 2017)The boreal biome, representing approximately one-third of remaining global forests, provides a number of crucial ecosystem services. A particular challenge in forest ecosystems is to reconcile demand for an increased timber ... -
