Resumen: The design process of the F-110 frigate for the Spanish Navy is still underway. This work aims to support the decision of the Navy, on the configuration of secondary artillery of the new F-110 frigate. To do this, in this case study, we use and develop a methodology based on an analytical decision maker built ad hoc. This decision-making methodology allows reducing the present subjectivity based on an analytic hierarchy process algorithm. Using objective tools such as numerical simulation and statistical techniques, we are able to evaluate objectively the contributions of the alternatives to different criteria.
