The block scheme of the decision support system. The system is divided into four processing blocks (bordered with dashed black rectangles). The inputs to the blocks are the calculated features: ${\alpha }_{av}$, $f_{av}^{\left(i\right)}{i}_{dec}$, and $H_{num},F_{num},$ respectively. Each block implements rules and assigns a subscore for the input feature. The final score $S_{FT}$ is decided based on the results obtained from all four blocks.
