A partir de esta tabla, genera una descripci\u00f3n escrita del proceso. La calidad de la SET es fundamental para el resultado de la descripci\u00f3n: cometer unos pocos errores cr\u00edticos en la SET har\u00e1 que toda la descripci\u00f3n sea incorrecta.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Por esta raz\u00f3n, PFD Bench cuenta con un paso de intervenci\u00f3n humana en el bucle justo despu\u00e9s de la extracci\u00f3n de SET, para que el usuario tenga la oportunidad de corregir cualquier error cometido por la IA. Adem\u00e1s, ejecutamos bucles de evaluaci\u00f3n para medir la calidad de la extracci\u00f3n de SET en comparaci\u00f3n con tablas de referencia comisariadas por un ingeniero de procesos s\u00e9nior, en 8 diagramas de flujo de procesos industriales reales. Si bien no podemos compartir los diagramas con el p\u00fablico (est\u00e1n bajo acuerdo de confidencialidad), podemos mostrar los resultados de la evaluaci\u00f3n y estad\u00edsticas aproximadas sobre la complejidad de cada dibujo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La evaluaci\u00f3n se realiza procesando cada dibujo 10 veces de forma independiente (80 ejecuciones en total) con la misma configuraci\u00f3n que tienen todos los usuarios en PFD Bench. Actualmente, los SET se procesan con Google Gemini 2.5 Pro. Las cifras a continuaci\u00f3n incluyen la dispersi\u00f3n entre ejecuciones, por lo que se puede ver no solo la calidad de extracci\u00f3n en promedio, sino tambi\u00e9n su varianza.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Los dibujos<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Complejidad en t\u00e9rminos sencillos: cu\u00e1ntas unidades de equipo y cu\u00e1ntas conexiones de flujos documentadas hay entre ellas. La densidad (conexiones por unidad) es lo que hace que un plano sea especialmente dif\u00edcil. Las plantas altamente interconectadas son m\u00e1s dif\u00edciles de rastrear que los trenes lineales.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Dibujo<\/th><th>Unidades de equipo<\/th><th>Conexiones de transmisi\u00f3n<\/th><th>Densidad<\/th><\/tr><\/thead><tbody><tr><td>pfd_03<\/td><td>8<\/td><td>20<\/td><td>2.5<\/td><\/tr><tr><td>pfd_04<\/td><td>20<\/td><td>53<\/td><td>2.6<\/td><\/tr><tr><td>pfd_05<\/td><td>18<\/td><td>46<\/td><td>2.6<\/td><\/tr><tr><td>pfd_06<\/td><td>19<\/td><td>48<\/td><td>2.5<\/td><\/tr><tr><td>pfd_07<\/td><td>33<\/td><td>175<\/td><td><strong>5.3<\/strong><\/td><\/tr><tr><td>pfd_08<\/td><td>32<\/td><td>116<\/td><td><strong>3.6<\/strong><\/td><\/tr><tr><td>pfd_09<\/td><td>29<\/td><td>69<\/td><td>2.4<\/td><\/tr><tr><td>pfd_10<\/td><td>28<\/td><td>83<\/td><td>3.0<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Resultados<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Las puntuaciones son <strong>F1 \u00d7 100<\/strong> (see &#8220;How to read these numbers&#8221; below), one column per field of the extracted table: mean \u00b1 standard deviation over the 10 runs.
