Capability prediction : effective anticipation support in ship control
other
A simulator study was carried out to quantify the potential benefits of prediction information to support operator anticipation in ship control.
Twelve participants were asked to navigate a medium size vessel across a busy vessel traffic separation scheme. Three integrated navigation display types were used: (i) basic automatic radar plotting aid (ARPA) information which can be considered as a modern baseline navigation display type, (ii) basic ARPA with additional information indicating the predicted boundaries of operation, the so-called Predicted Capability Envelope (PCE), and advising about safest course to select, and (iii) basic ARPA with PCE for variable propulsion of the navigator's vessel, advising about safest course and speed to select. The experimental trials were performed under normal and high-workload task conditions. Performance was measured in terms of safe and efficient navigation. Results of the experiment show that navigation performance considerably increased when capability prediction information was provided.

Uit de resultaten van een serie simulatorexperimenten bleek dat nauwkeurig stuurgedrag bij supervisory control van vaartuigen alleen optreedt wanneer naast het geplande traject (preview) informatie beschikbaar is over het voorspelde traject (path prediction) en over de voorspelde manoeuvreerruimte (capability prediciton).
