Version 2.12

Summary

• Next version will be labelled 2.12 and is planned for release in October 2018.
• It will contain new functonality in RegWise to allow for simulation of land use changes. Until now the only land use supported been "Productive forest land". A new control table called "LandUse" has been added to the Domain Settings-type control category (RegWise only). Using this functionality requires a special-purpose adapted forest database.
• Low-productive forest land is a now supported as land-use type, and new growth functions has been developed for this (Kenneth Nyström 2018).
• The bucking algorithm (utbytesberäkningen) now includes a possibility to let roundwood logs (both timber and pulpwwod) be downgraded to fuelwood. This is a decision made at the harvesting site, so fuelwood will handled as a distinct assortment and put in its own pile of logs at the road side. There are separate settings for pulpwood and timber. For example, you could enter a higher downgrading proportion for pulpwood. Timber can be downgraded to pulpwwod, fuel wood and to waste. Pulpwood can be downgraded to fuelwood and waste. Fuelwood from downgraded logs is reported as a new assortment, in volume units. This is distinct from harvest residues which is reported in biomass dry weight units (branches and tree tops, and whole trees from bio fuel thinnings).
• Waste (vrak) refers to logs downgraded at the industry but has until now only been accounted for as a decrease in saw timber revenue. Now the volume is explicitly reported, from downgrading of timber and pulpwood. This means that the timber volume and pulpwood volume will be smaller in the new version if you have had a postive value for the waste proportion in the timber pricelist. A new result variable called "Waste Volume All Species" has now been added to result group Financial Value.
• The default price for waste has been changed from 80 to 0 SEK per volume unit.

• The HeurekaAPI has several fixes

0000238	TPG	major	TPG Exception	2.12.2	fixed
0000239	TPG	crash	Fel i prislista med pristrend	2.12.2	fixed
0000236	Project handling	minor	When selecting entire areas, initial state will be calculated multiple times	2.12.2	fixed
0000235	Optimization	minor	Can not save CSV in optimization results column view	2.12.2	fixed
0000237	Data import	major	Värden mappas till fel kolumner	2.12.2	fixed
0000225	TPG	major	Exception and suspected error in NPV-calculation in tactical TPG	2.12.0	fixed	Soil expectation value and terminal value were incorrectly calculated when the final felling treatment occurred in the period after the last planning period.
0000227	TPG	major	No harvest revenues are reported if a schedule includes biofuel thinning	2.12.0	fixed	Error introduced in version 2.11. If young stand thinning type was set to "Biofuel thinning", then in subsequent thinning and final fellings, all roundwood was extracted as bio fuel instead of timber and pulpwood.
0000216	RegWise simulation	minor	"Show simulation report" that displays simulation settings is not available in RegWise	2.12.0	fixed
0000217	RegWise simulation	major	Even if all random seeds are set to fixed value, unexpected differences between simulation occur	2.12.0	fixed	Even if all random seed were set to fixed values, two simulation results that weer expected to be identical were not. Reason was that for some function, the random seed could not be set to a fixed value.
0000234	RegWise simulation	major	Changing database will disable selection of inventory years	2.12.0	fixed
0000231	Project handling	trivial	Opening the database name combo box closes it immediatelly	2.12.0	fixed
0000218	Project handling	major	Application throws error message when double clicking project from Windows Explorer	2.12.0	fixed	The project is now loaded AFTER the entire main form has finished loading
0000219	Project handling	minor	Loading previous databases locks the GUI	2.12.0	fixed
0000221	Project handling	minor	Random seeds in too many different locations	2.12.0	fixed	Random seed is now configured in the Simulation dialog only. An additional random seed is added to RegWise for Control category assignment
0000222	Other	feature	New function: Allow tIme consumption to increase for harvesting operations in storm felled stands	2.12.0	open
0000215	Other	minor	Rerun simulations doesn't calculate alternatives for unmanaged treatment units	2.12.0	fixed	(RegWise) When running the function "Rerun simulation" on a simulation that included both unmanaged and evenaged management programs, the unmanaged programs were not recreated.
0000224	Other	minor	Pricelist name changes are not saved	2.12.0	fixed
0000233	Other	minor	Program crashes if user lacks write permission on custom Common directory	2.12.0	fixed
0000229	Other	minor	Zips fails to be extracted	2.12.0	fixed	Zip files can sometimes fail to extract, probably due to system culture settings.
0000230	Optimization	trivial	MissingValueSubstitute is redundant in optimization model	2.12.0	fixed
0000220	Optimization	feature	Incorrect solver finished message for some solvers	2.12.0	fixed	LPSolve, and maybe others, will not return an "Infeasible" solver status when a solution could not be found. The resulting dialog showed a confusing error message.
0000232	General	minor	Path in Path Settings not used for some features	2.12.0	fixed
0000228	Forest Domain Builder	minor	Trying to cancel deletion of control category seemingly fails	2.12.0	fixed	If you right-clicked a control category to delete it, but aborted the delete-operation by choosing Cancel, the control category apparently was removed anyway. But it was actually still there, if you reopened the project you could see it had not been deleted. The expected behaviour is of course that it should be visible after choosing Cancel which has no wbeen fixed.
0000223	Control categories	minor	ManagementSystem result sometimes lacks value	2.12.0	fixed
0000226	Control categories	minor	Reference error when loading multiple control tables of the same type from file	2.12.0	fixed	Newly deserialized control tables will always be a new instance instead of a cached copy of a previous instance
