To reduce the losses of timber in the process of manufacturing panel construction products made of edged timber, it is proposed to saw the logs into boards of trapezoidal and rectangular cross-sections. The computer technique of optimization of the schematic model parameters for sawing the log into a given even number of boards of rectangular and trapezoidal cross-sections is developed. This determines the number of trapezoidal section boards and the angle between the face and the edge, which

... the same for all such boards. The research was carried out by the method of mathematical modeling. Tasks of finding rational values for the parameters of log sawing schemes are solved using numerical hill-climbing methods.
