This report describes a dynamic, computer-assisted simulation model for planning and management tasks in Swiss forestry. The parameters duplicated are regeneration, tending, thinning, final cutting, growth, and the harvesting costs and yields from various assortments per stand. Changing environmental conditions are also taken into consideration. The function parameters were fed into the model via ASCII files and could be modified without changing the programme. An easily applied menu and dialogue user interface is available for system steering, data registration and data output. The article gives examples of the application of the model in long- and medium-term forest management planning, illustrating the effects of profit and loss in a forest enterprise, quantifying the loss in value due to bark peeling damage, and showing how intensification of wood production can be balanced against extensification. Test studies have proved the reliability of this model
