Optimal asset network planning for counter piracy operation support, part 2: Results

The optimization approach proposed and detailed in [1],[2] is tested here on a maritime scenario making use of real meteorological and oceanographic (METOC) hindcast data and satellite automatic identification system (AIS) performance surfaces. The region of interest (ROI) is in the Indian Ocean, facing the Horn of Africa. Simulated assets include frigate class ships equipped with sensing capabilities, having a maximum range of 100 km, constant detection probability P_D = 0.8, and false-alarm probability P_FA = 0.001, with a cruise speed of 20 knots (10 m/s). The feasible regions for the control actions are Ω_r = [100,300] km and Ω_θ = [θ̅ km and deg, where is the ship direction of arrival to the last reached waypoint.
