Abstract
We report on the development of a new decision support system for transportation planning in Swedish forestry. The system deals both with strategic and tactical decisions. Strategic decisions concern usage of train system, terminal location and capacity, and wood bartering between companies and/or organizations. In tactical planning we consider decisions on catchment areas, destination of supply points and potential back-haulage routes. The system uses a GIS-based map user-interface. Two important modules in the system are the new Swedish road database and an optimization module consisting of a suite of models and methods. The development has included several organizations and forest companies. We discuss two case studies at participating companies that illustrate the usage of the system.
