A method based on the Metropolis algorithm is developed for creating desirable spatial configurations on the landscape while simultaneously dealing with other objectives commonly associated with harvest scheduling. Spatial configurations are loosely specified and stochastically attained, which contrasts with other adjacency constraints based on specific block size limits. This method makes it possible to improve habitat and connectivity, and to create buffer zones as part of the scheduling process. It also works with a mapped set of polygons/forest stands and does not require a gridded system.

Abstract | View details | Full text in PDF | Author Info

Application of the Metropolis algorithm for forest harvest scheduling is extended by automating the relative weighting of objective function components. Previous applications of the Metropolis algorithm require the user to specify these weights, which demands substantial trial and error in practice. This modification allows for general incorporation of objective function components that are either periodic or spatial in nature. A generic set of objective function components is developed to facilitate harvest scheduling for a wide range of problems. The resulting algorithm generates multiple feasible solutions rather than a single optimal solution.
