Towards a Human Operator Model of the Navigator

摘要

The study is aimed at investigating the feasibility of a general purpose humanoperator model of the navigator. Maneuvering issues in the realm of fairway design and fairway regulation and legislation are met in sea navigation as well as in inland waterway navigation. Consequently, it was decided that the field of application of the navigator model to spring from the study should range from navigating large deep-sea vessels to steering small inland vessels. The common factor is that practically always the waterway is more or less confined in relation to the dimensions and maneuvering characteristics of the vessel concerned. Further, for a human operator model of the navigator to be of any practical relevance, it is necessary that a variety of strategic and tactical aspects of the navigator's behavior be covered by the navigator model, in a clearly distinguished way. To be more precise, explicit modeling of planning, control and state estimation behavior is expected to be indispensable. An isolated navigator model, not coupled or fit to be coupled to suitable models of a ship and a fairway, is of no use. And what is more, it would be impossible for such a model to come into existence, every possibility to test or validate it being excluded. So, building a prototype navigator model inevitably implies the creation of a testing environment to complement it, thus arriving at a complete navigation simulation facility.
