Productivity models for wood harvesting operations

The wood harvesting productivity model HeProMo enables an easy and rapid assessment of time duration, productivity and cost for various wood harvesting operations. In an extensive rework the models have been updated and completed with new models missing so far, particularly with data regarding full-tree harvesting operations using a tower yarder with a mounted processor as well as harvesting operations for energy wood. Furthermore models for evaluation of stem wood volume, energy wood volume and biomass volume have been created.

Productivity models for harvesting operations

The computer based productivity model HeProMo allows productivity and cost calculations for various wood harvesting operations. Potential users are forest enterprises, private forest operators, forest administrations as well as researchers and scientists.

The main application areas of HeProMo are:

  • estimation of productivity and cost for wood harvesting operations (preliminary calculation)
  • making and reviewing offers for wood harvesting operations
  • easy checking of the influence of the entry values on the result (sensitivity analysis)
  • utilisation in teaching

The productivity models are programmed in Java wherefore they can be used on any IT platform. They are equipped with a user-friendly menu navigation. For every single model the basic data and the modelling process are well documented and integrated into the model.
