Reliability informed routing for Autonomous Sailing Craft

EasyChair Preprint 326

Abstract

This paper introduces a novel method for modelling the influence of likely autonomous sailing craft failure conditions into the route planning algorithm. The accuracy of the original route planning algorithm is quantified using numerical error estimation techniques. It was found that over the course of a Trans Atlantic voyage a grid size of 36 km produced an error of +/- 2 hours over the course of a $36.5$ day voyage. The implementation of the failure model within the routing algorithm is verified using a control weather scenario. This verification is shown to be significant with respect to the method's numerical error. Future work will involve gathering evidence on failure criteria in order to update the failure model.
