This research aimed to analyze the production cost of lumber using randomized and programmed cutting systems for different diameter classes. We selected 80 logs of Pinus spp with diameters ranging from 24 to 33 cm, divided in four diameter classes, with 20 logs per class. In each class, the logs were separated in two lots of 10 units - the first batch was subjected to randomized cutting and the second batch was submitted to programmed cutting. The cost analysis showed that there was reduction in values when the programmed cutting system was used.
