HOLZERNTE provides computer-aided decision support for the timber harvesting and marketing sectors by allowing the user to perform both preliminary and final costing analysis of harvesting operations. While the derivation of stumpage value figures is central to the programme, further information such as time expenditure, labour costs and material costs can also be calculated.

The programme permits the inclusion of all the usual processing and delivery considerations, and allows the user to examine the influence of a range of factors on the stumpage value by comparing the results of various simulations. Factors such as assortment and harvest selection, quality classification, timber price, operational costs, salary rates, harvesting methods and workflow steps can all be modified to investigate the effects on stumpage value.

Even if a forestry enterprise is limited to certain harvesting methods due to a lack of alternatives, increasing operational costs mean that enterprises nevertheless require computer-aided decision-making to calculate profitability. This is particularly import when organising self-employed forest workers.

Abrupt changes in the timber market and a growing tendency towards buyer-oriented timber grading present rapidly changing demands on the timber producer, in terms of time and location.

HOLZERNTE provides a flexible and practically-orientated grading of timber products, and is thereby an important instrument for modern timber marketing. The programme allows the user to plan the most profitable harvesting solution by adapting predefined harvests to correspond with buyer demands for various assortment options, price ideas or log lengths.

Further areas of application include:

  • Planning yearly harvesting activities and timber assortments
  • Forest enterprise business analysis
  • Deriving standard costs for accounting purposes
  • Calculating the costs and time allocation of motor-manual harvesting methods
  • Creating regional harvest assortment and stand assortment tables
  • Harvest valuation
  • Sales of standing trees
  • Many more
