1. 1. Managing timber procurement in Nordic purchasing sawmills

   Författare :Klara Helstad; Rolf Björheden; Lars-Olof Rask; Anders Baudin; Lauri Sikanen; Växjö universitet; []
   Nyckelord :Procurement management; Sawmill industry; Supply uncertainties; Buyer-supplier relationships; Bucking; Contractual forms; Strategy; Case Studies; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING;

   Sammanfattning : Procurement of sawlogs to purchasing sawmills represents a basic strategic business process. The properties of inbound sawlogs are decisive for the output of sawn products and the cost of raw material contributes substantially to the cost of the final product. LÄS MER

3. 2. Integrating the bucking operation with production control in sawmilling

   Författare :Urban Nordmark; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Sammanfattning : There is an ongoing shift in production strategy in the sawmill industry in Scandinavia from bulk production of standard grades towards customer- oriented production of well-defined products. The bucking operation places limits on the timber that can be sawn from the logs. Thus, it is important to be able to control the bucking process. LÄS MER

4. 3. Value recovery and production control in the forestry-wood chain using simulation technique

   Författare :Urban Nordmark; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Sammanfattning : This thesis deals with value recovery and production control in the forestry–wood chain for improved competitiveness of sawmills through higher profit and better adaptation to product requirements of the customers. The subject was approached using simulation technique with a database of virtual logs and a sawing simulator capable of processing the logs in the database. LÄS MER

5. 4. Measurement accuracy in the forestry-wood chain

   Författare :Sorin Chiorescu; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Sammanfattning : A customer-oriented production philosophy and an integrated forestry-wood chain are concepts that researchers and people involved in the forest industry have to deal with in the beginning of this new millennium. Fulfilling the specific requirements for dimension, length or biological features that customers demand for the wood products entails the existence of accurate measurement equipment at each location along the conversion chain.

7. 5. Automatic tracking of wood

   Författare :Richard Uusijärvi; KTH; []
   Nyckelord :;

   Sammanfattning : Proper industrial utilisation of wood is difficult, becausewood is a biological material and wood properties vary greatly.Also the knowledge of wood parameters is insufficient. A reasonfor this is the difficulty getting sufficient amounts of datafor statistically overcoming the variability of the material–a tedious and almost impossible task. LÄS MER
