To do this, sawmill managers have to decide which cutting patterns have to be applied to logs of different dimensions.
Optimization models have been proposed to assist decision makers in this process, but only the profit maximization and the cost minimization of the decisions have been considered as the models objective.
In this paper, a linear optimization model was formulated to address lumber production planning and applied to a real problem.
The current decisions at sawmills were compared with five different objective functions: the two previously mentioned plus waste minimization, log number minimization and production t...
