A cost benefit analysis of the Fleet Numerical Oceanography Center (FNOC) is conducted with specific attention to the Optimum Path Aircraft Routing System and the Optimum Track Ship Routing Systems. These two products out of the many produced by FNOC comprise the bulk of the savings realized by the U.S. Navy through FNOC's work. The Optimum Path Aircraft Routing System (OPARD) is evaluated using the modified flight plans received by the system. These plans were resubmitted to OPARS to determine the range of fuel usage around the optimum provided by OPARS. The Optimum Track Ship Routing System (OTSR) is evaluated using an adaptation of Dijkstra's algorithm to determine the optimum routing if perfect wave height information were available compared to a purely greedy strategy capturing the shortest arc available enroute to the destination. The damage sustained is compared to actual damage reported to the Naval Safety Center to determine the savings to the U.S. Navy from the OTSR system.
