Application of the Analytical Hierarchy Process for the Selection and Deployment of Deepwater Search and Rescue Vehicles

Abstract

The Spanish Navy is immersed in a process of modernisation and acquisition of new naval systems, such as S-80 submarines and a BAM-IS (Underwater Intervention Maritime Action Vessel) underwater intervention vessel, and in this regard, technological advances require increasing the capabilities of submarines for rescue and salvage operations. The study investigates the potential benefits of a submersible compared to a remotely operated vehicle or an autonomous system using the Analytical Hierarchical Process (AHP) method devised by Thomas L. Saaty.

This empirical study provides an objective evaluation and comparison of the key criteria involved in choosing a vehicle that is suited for use at great depths, while considering the specific needs and requirements of the Spanish Navy. The evaluation criteria include many elements such as mobility, operational depth, cargo capacity, autonomy, and human-machine interaction. Although still in the developmental stage, autonomous systems possess specific characteristics that make them well-suited for submarine rescue missions.
