The productivity model HeProMo (Holzernte-Produktivitäts-Modelle) enables the estimation of time consumption, productivity and costs for different harvesting operations in an easy and rapid way. Over the years the basic data of several models have become rather out-dated, for which reason, in a first step, the productivity models for "Motor-manual felling and processing", "Skidder" and "Harvester" have been updated.
The productivity model HeProMo is based on information technology and may be used by different user groups: forest enterprises, forest operators, forest administrations, forest schools and research institutes.
The main applications are the followings:
The three updated models and the out-dated ones as well have been programmed in Java. Thus the productivity models run independently from the platform. They are user-friendly structured and each model is documented elaborately in terms of basic data and model building.
The sourcing of reliable basic data has been a great challenge at the updating of the three productivity models "Motor-manual felling and processing", "Skidder" and "Harvester". We succeeded in obtaining a lot of basic data from forest enterprises in Germany. But these data sets only have a few parameters as the data were not registered in order to build productivity models.
For this reason in the register "Models with out-dated data base" the former version of the productivity models for "Motor-manual felling and processing", "Skidder" and "Harvester" is still available. Furthermore these models may be usefull, e.g. to investigate the influence of a certain parameter on the productivity.
