Instruments of raw wood supply logistics

(sScale-system, wet storage model, results from current research projects)

This station focusses on two independent instruments of raw wood supply logistics.

  • The image-scanning wood stack scaling method is fully integrated into the overall logistics process via a server-based stack management system and is growing in importance in regular forestry.
  • An innovative roundwood wet-storage approach designed for calamity situations: the stems are stored in a mobile, modular expandable concept as a closed cycle system on a plastic sheet.

1. The stack scaling system sScale was first presented at the KWF-Tagung in 2008. However much has changed since then.

In some federal states, the technological approach has developed into the centrepiece of wood supply logistics. The method provides a precise scaling of roundwood stacks and a simple means for recording and registering of the stacks by the responsible manager and is integrated in a server-based stack management system. This system allows the user to control stack scaling as well as all follow-up processes, such as transport, billing etc..

Both the technology and user-friendliness are continually being optimized. This optimization process is adapted individually to suit the user's requirements in terms of data transfer interfaces, export formats and integration into existing computer systems. Current research carried out by the  FH-Erfurt demonstrates the potential of this technology for supporting and optimizing the roundwood supply chain in forest ventures using concrete scenarios.

At this station, the company Dralle will demonstrate image-scanning technology and function as well as the available options for server-based logistic portals for stack management. The presentation will also include an overview of the current state of research  to quality management and precision of image-scanning wood stack scaling methods.

2.Wet storage is a proven method for storing large volumes of wood in the wake of calamities. The wood is conserved and stored for long periods of time in a while without loss of quality. One of the weak points of conventional wet storage methods is the enormous demand for water, which usually means that the stacks must be sited in the vicinity of a natural source of water. This reduces the number of suitable sites in any given area considerably. Experience shows that local water and conservation authorities are reluctant to authorize conventional wet storage sites because of the severe interference with sensitive ecosystems. In addition to this, the authorization procedure must take into consideration a vast range of topics, making it next to impossible for these authorities to make rapid decisions. However speed is essential when dealing with storm damaged wood following a calamity. Models, system elements and animations are used at this station to present the innovative wet storage concept for 20,000 to 30,000 cubic meters wood. The presentation showcases new approaches for simplifying the authorization procedure, how the system achieves independence from a water source and a stationary power supply, and an adaptable irrigation control with standardized maintenance management with an automatic disruption manager for the system. The unique system features  as well as economical, social and ecological aspects will be demonstrated at this station.
