Mathematical programming and computers have been used for several decades to solve complex and long term forest management planning problems. The ever increasing demand on the forest ecosystem to produce wood and other goods and services poses a corresponding demand on a forest decision support system. As a response to meet new requirements the development(More)
Many forest planning situations are complex; multiple criteria of different natures have to be considered and several stakeholders or social groups may be involved. An approach that is increasingly used in these complex situations is the combination of multiple criteria decision analysis (MCDA) and participatory planning. A crucial part of MCDA processes(More)
Forest planning in Sweden today translates not only into planning of timber production, but also for the provision of other functions and services. Multi-criteria decision analysis (MCDA) methods provide a way to take also non-monetary values into account in planning. The purpose of this study was to gain experience on how to use a forest decision support(More)
Keywords: climate change; forest management planning under uncertainty; reinforcement learning EXTENDED ABSTRACT Forest management is classically modeled as a deterministic planning problem where decisions are determined in advance unconditionally to future events. This approach has led to the development of efficient optimization methods based on linear(More)
Using wood as a building material affects the carbon balance through several mechanisms. This paper describes a modelling approach that integrates a wood product substitution model, a global partial equilibrium model, a regional forest model and a stand-level model. Three different scenarios were compared with a business-as-usual scenario over a 23-year(More)
EXTENDED ABSTRACT When selecting a long-term silvicultural management policy for a forest, a number of stochastic events can be taken into account in order to improve the management of the forest and thereby increase its value. A stochastic event that has recently been given a lot of attention to is the damage to forests due to windstorms. This is an(More)
Forest-owning companies in Sweden have both a goal to yield a good short-term rate of return on their forest and a goal to maintain a high long-term rate of return by maintaining the production of wood-based products. Both these objectives are taken into account in the forest planning process. For the long-term goal, the companies develop strategies(More)
