Abstract

The effectiveness and efficiency of mine-hunting operations with autonomous underwater vehicles (AUVs) are greatly influenced by environmental conditions, such as seabed, turbidity, currents, and tides. Therefore accurate environmental information is needed for the planning and evaluation of mine-hunting operations. Because environmental conditions can change rapidly and frequently with time and location, a priori planning is not optimal and can hinder the achievement of the mission objectives. It is therefore important to have a capability to monitor whether environmental conditions deviate from those used for the mission planning, and to evaluate the consequences on the effectiveness and efficiency of the mission. Based on this information, decisions can be made whether the mission plan needs to be modified, or whether changes to the AUV’s behaviour are required. We develop a technique for monitoring the mission progress based on in situ information. This information is subsequently used to perform optimization of the individual mine-hunting tasks. Such a process is referred to as utility-based optimization and is expected to be critical in achieving robust mine-hunting missions with AUVs with a predictable performance
