Multi criteria decision making

Aug 17, 2015

Multi criteria decision making and participatory planning  TIMBHAS™ Does you or your company spend too much time on developing tactical plans for the stands to be harvested in the coming years? Then TIMBHAS™ may be the solution for you and your company! Read more Multi criteria decision making and participatory planning An exciting, relatively new feature in Heureka is the PlanEval application that can be used as a tool to compare the various options that have been developed with PlanWise. With PlanEval, the decision making is structurized (which option best meets the goals and requirements) into a number of objectives. Examples of objectives can be timber production and nature conservation. You can then specify how each of these objectives shall be measured by specifying one or more criteria for each objective. For timber production you can, for example, enter felling volume for a given period or periods and the net present value. For conservation you can for example enter the area of protected forest and area of older forest. The project manager then adds the persons (stakeholders) to be included in an evaluation group. Each stakeholder then scores each action (via the web) based on how good it is for a particular criterion. This method is based on scientific articles published on the subject participatory planning and multi-criteria planning. TreeSys is well versed in how PlanEval works and can assist with project managing such a process. About TreeSys Click here to read more about us!

Strategic analysis

Aug 17, 2015

Strategic analysis and long-term forest management plans  TIMBHAS™ Does you or your company spend too much time on developing tactical plans for the stands to be harvested in the coming years? Then TIMBHAS™ may be the solution for you and your company! Read more Strategic planning and long-term forest management plans Strategic forestry planning aims at determining how much, when and possible where to havest, taking into account long-term sustainability aspects. Sustainability typically include not only production and economy, but also biological diversity, social values and other interests. To understand the long-term consequences, it is common to use a 100-year planning horizon in boreal forestry. TreeSys is specialized in using the Swedish forestry decision support system Heureka developed by SLU. Heureka has lately attracted some interest from abroad and now offers possibilites to plugin custom growth models. Hopefully  in the future other types of models will be possibile to plugin as well, thus opening up for using Heureka in any country. A strategic plan can be made either with a stratified sample or with the whole stand database as input. The advantage of an objective sample is that it can calculate the uncertainties in the estimates and minimize risk of misjudgements. The advantage of including every stand is to directly get stand level management proposals. TreeSys recommends using both types of data; the sample-based analysis is done first and then, if the results differ too much, use it for calibration of the stand analysis. Using Heureka is often perceived as a “sweaty but rewarding” exercise. You are forced to consider issues that you might not even have thought of. Often there are several alternative courses of action, all of which are...

Impact assessments

Jul 14, 2015

Impact assessments  TIMBHAS™ Does you or your company spend too much time on developing tactical plans for the stands to be harvested in the coming years? Then TIMBHAS™ may be the solution for you and your company! Read more Impact assessments An impact assessment or analysis is in many ways similar to strategic planning but has a different focus. While a strategic plan answers the question “How?” an impact assessment answers the question “What if?”. The line between these questions is not always obvious and while working with a strategic analysis the question “What if” often arise, and vice versa. The interested party does not need be a forest owner but might just as well be a government agency or a research project. Impact assessments may be interesting to perform both at the stand level (for “type stands”) or for larger areas such as regions or the entire country. One example of where TreeSys has performed an impact assessment is a computation for the Swedish Forest Agency report on turnaround times (Skogsstyrelsen 2015), which analyzed both stand and country levels to examine to what extent an amendment to the lowest permissible age for final felling can affect the long-term level of output. Another example of TreeSys participation is a research project at SLU analyzing why a mountainous area was deforested long ago. Heureka was used to simulate the development of birch forests assuming different levels of wood consumption for domestic use. About TreeSys Click here to read more about us!
