Abstract: A method of controlling processing of wood particles into engineered wood products includes sensing interaction information associated with interaction between a plurality of steps in manufacturing the engineered wood products, or interaction between a plurality of properties associated with materials used to make the engineered wood products, or interaction between said plurality of steps and said plurality of properties, or interaction between said plurality of steps or said plurality of properties and an additional external factor which is external to said plurality of steps or said plurality of properties, processing the interaction information with machine learning and deriving from the machine learning improvement information associated with improving properties or yields or profitability of the engineered wood products, and implementing the improvement information back in the processing of the wood particles to achieve engineered wood products with improved properties or yields or profitability.
