Version benchmarking

Here we present a comparison between different versions for a benchmark problem run in PlanWise. We call this problem Hexagons1000, it can be downloaded from here. The problem consists of one thousand simulated treatment units. The results refer to an optimization with simple even-flow constraints. The TPG-simulation includes nine forest domains and the somewhat time-consuming breeding model is activated. For each treatment unit managed with even-aged management a nature conservation retention patch is created resulting in a total of ? units. The forest is a simulated but realistic landscape with respect to age classes, site fertilities and tree species distribution.

The comparison is intended to present to users a simple form of quality and status check and give some insigth into what can be expected. Net present value is an excellent indicator for whether there has been any model changes, since it basically depends on everything calculated by the growth-and-yield simulator.

This page was/is first published with version 2.11. We intend to run the benchmark problem for each major version released.
