Popis:	This paper proposes a methodology for generating optimal cutting patterns in sawmills operations that minimize waste production. Firstly, a linear programming model was used to generate patterns of feasible and optimal cuts for different diameter classes. Secondly, a model which assigns efficient cutting patterns based on the supply and demand of the timber yard was employed. A total of 42 cutting patterns were assessed with a utilization level of 79 %. Levels of loss were around 25 % depending on the characteristics of the raw material.
