Habplan3 is a program for forest harvest and habitat scheduling.

Platform

Habplan is a landscape management and harvest scheduling program. Habplan allows you to build an objective function from the supplied components that show up as checkboxes on the main Habplan form. Habplan was designed to deal with spatial objectives, but can be used for harvest scheduling where there are no spatial or adjacency issues as well. Habplan can schedule multiple districts and can therefore handle strategic and tactical planning simultaneously. Habplan selects from management regimes that the user indicates are allowable for each polygon (stand). Any polygon may have from one to hundreds of allowed regimes. A regime encompasses everything that will be done to that polygon over the planning period. Regimes can therefore be multi-period, i.e. have multiple years where actions and outputs will occur. Habplan can handle plans involving thousands of polygons and regimes over long planning horizons. The limits depend only on the capacity of your computer. Habplan attempts to find the best overall management schedule using the Metropolis Algorithm, an optimization heuristic similar to simulated annealing. Habplan also integrates a linear programming module, which enables finding optimum non-spatial schedules for small problems.
