=== Scope of the system === DSD supports two main silvicultural decision-making problems, both for individual stands: # The establishment of new stands. It seeks which species or species mixtures are suitable at particular locations within the project area, including considerations of the effect of climate change. # Stand treatments scheduling, given a particular set of management objectives aiming at a future species-mixture stand type. === System origin === * It was developed by a researchers team in the Universität für Bodenkultur Wien. First prototype was implemented in 2001. * how was it developed * is it a commercial product * Is in use in southern Austria. === Support for specific issues === Timber harvest effects, climate change effects, risk assesment methods, biodiversity, and site improvement. === Support for specific thematic areas of a problem type === * Silvicultural * Certification * Conservation * Restoration * Development choices / land use zoning * Policy/intervention alternatives === Capability to support decision making phases === * Intelligence: *: DSD requires from the user the insertion of forest features data and management objectives. * Design: *: For each stand objective different schedules and results are proposed, that then would be evaluated according to the management objectives. * Choice: *: The selection among the different management possibilities is made according to the predefined objectives using multicriteria evaluation. * Monitor: *: It falls on the final manager. === Related systems === * [[SDSS Wolschartwald]] * [[SDSS Wildalpen]] * [[CONES]] == Data and data models == === Typical spatial extent of application === Stand level. === Forest data input === Stand characteristics are input via GUI. === Type of information input from user (via GUI) === Users have to assign a particular forest property to one of the predefined site and stand categories, usin some easily available stand characteristics. They also have to choose the management objectives among the predefined ones employing pairwise comparisons. == Models == === Forest models === Growth and yield models are used to calculate costs and revenues. It has also an additive hierarchical utility model used in the multicriteria evaluation. == Decision Support == === Definition of management interventions === Manager is able to choose among three objectives: timber production, nature conservation and biodiversity, or mantaining or improving site productivity. === Typical temporal scale of application === Depending on the objective, a short- to mid-term (i.e., 30 years) as well as a long-term planning horizon is distinguished. === Decision-making processes and models === * Simulation (with and without stochasticity) * Multiple criteria/ranking == Output == === Types of outputs === Results can be viewed on the screen, stored in the database of DSD, and be printed in a comprehensive report. == System == === System requirements === * Operating Systems: Microsoft® Windows® OS * Development status: v1.1 has been released === Architecture and major DSS components === DSD was implemented in Borland® C++™ as a client/server architecture, with Oracle(R) as the relational database system. Thus, the inteface component of the program resides on the desktop computer of the user, and the application logic is on the central server of the forest region authorities. The GUI is completely based on Borland's VCL (Visual C Library), and the generation of reports is based on Quickreport™, which uses components of the Borland® C++™ programming environment. === Usage === DSD has been developed to support the staff of forestry extension services in the Dobrova region in preparing informed recommendations for forest management to small private landowners based on the owner's goal preferences. === Documentation and support === More information about DSD can be found at the [http://www.wabo.boku.ac.at/dsd.html?&L=1 DSD website], where e-mail directions of the responsible researchers are given.
