HERRERA-MEDINA, Jonnier Fabián  and  LEAL-PULIDO, Robert Orlando. Generating wood cutting patterns using mathematical programming for tactical-operative planification of sawmills. Colomb. for. [online]. 2012, vol.15, n.2, pp.227-245. ISSN 0120-0739.

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.

Keywords : algorithm; waste; cutting patterns; Pinus caribaea; linear programming.
