El Laboratorio Delphos desarrolla investigación en el área de planificación minera, en los temas de:

• Planificación de Minas a Rajo abierto de Largo Plazo: Desarrollo de modelos y algoritmos para la determinar el mejor negocio posible bajo restricciones de capacidad por períodos.
• Planificación de Minas a Rajo abierto de Mediano y Corto Plazo: Desarrollo de modelos, algoritmos y herramientas para la minimización de costos sujeto a metas de producción y bajo restricciones geométricas, de blending y medioambientales.
• Planificación Bajo Incertidumbre: Determinación de las mejores herramientas conceptuales y prácticas para la incorporación de la incertidumbre geológica, del sistema minero y del mercado para la construcción de planes robustos.
• Planificación de la Preparación Minera: Desarrollo de modelos y herramientas de planificación que construyan los planes de explotación desde la preparación para los mismos, con el fin de incrementar la robustez en las metas de producción, particularmente en los primeros años de los proyectos.
