Version 2.5.0
Summary
- This release note also covers changes released in updates 2.4.0.1-2.4.0.9
- Version 2.5 contains serveral improvements and bug fixes
- For PlanWise, the support for CPLEX optimization solver has been changed, see instructions in the Readme.txt file here: http://heureka2-1.slu.se/Filerepository/SolverLinks/Cplex/
New features
Help documentation on result variables and concepts
As you may know, the Heureka Wiki is used as a complement to the actual help document to give more in-depth documentation, for example about models, and to serve as a reference dictionary to certain terms and concepts. New pages are currently being added to give a concentrated overview of Result Variables and control table settings. A dictionary has also been added, which for example includes an explanation on how net present value is calculated.
Note that most of the variable explanations are more or less identical to those displayed as tool tips in the applications, but put in one place to give a better overview.
Check out the result variables documentation so far: Result Variables
...and the dictionary: Dictionary
Other changes
Marklund's biomass functions now default in new projects
Marklund's biomass functions are now the default biomass function when you create a new project. Marklund's function have been found to give more logical results since they include tree height. Information on what functions have been implemented can be found here: http://heurekaslu.org/wiki/Biomass_functions
Support for CPLEX solver changed
Due to somewhat unclear distributiion rights certain files owned by IBM CPLEX, the buult-in for CPLEX in PlanWise has been removed and replaced with a plugin. If you use CPLEX, there a a couple files you must copy to a certain directory to make it work. Instructions can be found here: http://heureka2-1.slu.se/Filerepository/SolverLinks/Cplex/
Bug fix: Third rotation not correct
In the treatment program generator (TPG), Heureka is often simulating three rotations. The third rotation has been too simplified, with a faulty timing of thinnings. Since the discounted value of that rotation is typically very small, the error should not have affected solution to any considerable extent, but the reported soil expectation values have not been correct. Read more about how soil expectation is calculated here: Heureka Dictionary: Soil expection value
Bug fix: Biomass in cut trees in precommercial thinning was not calculated
Result variables "Biomass in Cut Trees" in result group Treatment represent the amunt of biomass in cut trees, whether extacted from the forest or left as residues. For cleaning, this step was skipped but has no been fixed.
