Thus, the volume of material produced and used is steadily increasing while the range of applications keeps expanding. So far, attention has been paid mainly to primary production processes of wood fiber–plastic materials, while secondary manufacturing processes have attracted less attention. However, with the broadening applications of such materials and their increasing use, secondary manufacturing processes for wood fiber–plastic materials are gaining importance. This study investigated the performance of five commercially available wood fiber–plastic composite materials and solid wood (eastern white pine) with respect to tool wear and resulting material surface roughness. Large performance differences between different wood fiber–plastic composite materials and between solid wood and wood fiber–plastic composite materials with respect to tool wea...}, number={2}, journal={FOREST PRODUCTS JOURNAL}, author={Saloni, Daniel and Buehlmann, Urs and Lemaster, Richard L.}, year={2011}, pages={149–154} }

Most existing models are based on the assumption of a simple linear relationship between lumber grade mix and yield.

 @article{buehlmann_thomas_2002, title={Impact of human error on lumber yield in rough mills}, volume={18}, ISSN={["1879-2537"]}, DOI={10.1016/S0736-5845(02)00010-8}, abstractNote={Rough sawn, kiln-dried lumber contains characteristics such as knots and bark pockets that are considered by most people to be defects. When using boards to produce furniture components, these defects are removed to produce clear, defect-free parts. Currently, human operators identify and locate the unusable board areas containing defects. Errors in determining a defect and its location, known as operator error, lead to lower lumber yield and increased product cost. Technology exists that would alleviate these problems and is a viable option to avoid wasting lumber because of human error. This study was performed in a rough mill collecting data on the errors made by humans when marking defects. Computer-based simulation tools were used to assess the significance of these errors. It was found that three-quarters of the decisions made by human operators are erroneous in some way resulting in an absolute yield loss of approximately 16.1%. Thus, automated defect detection systems that perform more accurately than do humans could have a payback period of 1 year or less.}, number={3-4}, journal={ROBOTICS AND COMPUTER-INTEGRATED MANUFACTURING}, author={Buehlmann, U and Thomas, RE}, year={2002}, pages={197–203} }

While various linear programming formulations for this problem have been proposed, these models are often difficult to use and maintain for real-time decision making in a dynamic shop floor environment. This paper describes an MS Excel-based decision support system for wood panel manufacturing. The system is easy to use and maintain yet gives shop floor personnel access to powerful optimization capabilities useful for fine-tuning production processes in the face of changing supply and price situations.}, number={3}, journal={DECISION SUPPORT SYSTEMS}, author={Buehlmann, U and Ragsdale, CT and Gfeller, B}, year={2000}, month={Oct}, pages={207–227} }
