About the software

Software

The Heureka Forestry Decision Support System is a suite of freely available softwares developed and hosted by the Swedish University of Agricultural Sciences (SLU). The system covers the whole decision support process from data inventory to tools for selecting among plan alternatives with multi-criteria decision making techniques.

The software applications are intended for both large-scale and small-scale forestry and are designed for different users' specific problem areas:

• StandWise for stand-level analysis (sw: BeståndsVis)
• PlanWise for forest-level planning and analysis (sw: PlanVis)
• PlanEval is a multi-criteria decision making tool for comparing alternatives generated in PlanWise
• RegWise for regional and national scenario analysis (sw: RegVis)

Client platform

• Supported Operating Systems: Windows (Windows 10 and Windows 11).
• Heureka uses Microsoft SQL Server for storing in- and outdata. Supported versions are Sql Server 2019 and Sql Server 2022, although versions from 2008 R2 will probably work.
• .Net 4.8
