The objective of this study was to find an efficient method that allows time and yield increase volume use and utility of the sawmills that process logs pruned Pinus radiata, linking external information provided by a scanner industry and simulation of cylindrical defective core (CDC) in the constitution of a three-dimensional log, where the optimal cutting pattern was established by means of a dynamic programming algorithm. Sawing was simulated on a sample of 100 logs obtained randomly industrial process of scanning. The results were compared with those obtained by a heuristic developed by a company in the region. Dynamic programming algorithm achieved a yield of the raw material of 64% and an average relative net utility of 11 US$/log is obtained.
