Operations research based hierarchical harvest planning in Sweden and elsewhere
(English)Manuscript (preprint) (Other academic)
Harvest planning includes decision on different levels, both spatial and temporal,and is typically hierarchical in nature. Strategic forest planning includes decisions about nationwide forests and aims to maximize the sustainable production while preserving natural ecosystem processes and recreation areas on time horizons of one or several rotations, each representing 20-200 years. Tactical harvest planning decides which stands (or harvest areas) to be harvested over a several year rolling planning horizon under consideration of spatial aspects, e.g. road building and environmental concerns. On an operational level, annual plans are required for budgeting, contracting harvest teams and transportation companies and assuring road access. Moreover, managers decide weekly and monthly schedules for harvesting and transportation based on customer requirements. We provide an overview of hierarchical harvest planning and present the Swedish case. We also describe decision support systems, Operations Research (OR) models and methods more specific for the Swedish case, together with an international view of OR work within this problem area.
