Methods of mathematical (geometric) modeling are often used in the current research of multivariate processes and their optimization tasks combined with traditional mathematical methods of experiment planning. This simulation is carried out by methods of descriptive geometry, its practical values a graphical representation of the functional relationships of the quality from factors and parameters that define a process with number of variables more than three. Definition’s algorithms of the optimization based on the Radishchev drawingin the article are given to ensure the visibility of images and solve certain technical problems. The graphical model of the process optimization of joining parts of garments was constructed.
