  5. 3. The forestry-wood chain : simulation technique, measurement accuracy, traceability concept

    Author : Sorin Chiorescu; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Abstract : A customer-oriented production philosophy, an integrated forestry-wood chain and the global vision of Precision Forestry are concepts that researchers and people involved in the forest and wood industry have to deal with in the beginning of this new millennium. Fulfilling the specific requirements for dimension, length, biological features and proof-of-origin that customers demand for the wood products entails the existence of advanced methods and tools for understanding and thus controlling the production process along the forestry-wood value chain.
