21. An analysis of potential improvements within Lithuanian sawlog supply
Abstract : The wood supply from the forest to the industry is often characterized by high variability caused by the divergent structure of forest products, seasonality and uneven geographical distribution of forest resources and forest products industries. Based on previous knowledge on wood supply this thesis aimed to identify existing wood supply patterns and strategies in the Lithuanian state forest sector, to evaluate supply chain performance for sawmills and to examine potential improvements for roundwood transportation as well as handling operations at the sawmill.

22. Integrating the bucking operation with production control in sawmilling
Abstract : 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. READ MORE

23. Computed tomography of sawlogs : knot detection and sawing optimization
Abstract : Branches on trees introduce defects on sawn timber called knots. By scanning sawlogs using computed tomography, knots can be detected and accounted for so that the sawing process can be optimized with respect to outgoing product value. READ MORE

24. Measurement accuracy in the forestry-wood chain
Abstract : 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.

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