Complex ontology of research designing of marine dynamic objects

In the work the problems of the complex ontology in the dynamic structure of research designing of marine vessels and facilities of ocean development intelligent system are discussed. The conceptual model provides the designing of an ontology of seaworthiness in the complex dynamic environments due to nonlinear interaction of the objects with wind and wave disturbances. Domain ontology is based on the semantic model designing and analysis. The objects in the model are systemised on the basis of functional properties that belong to the class hierarchy. The relations define the system structure, and the elements identify the nodes function in the system. A formal model and the hierarchy structure of the ontology are shown within the paradigm of information processing in a multiprocessor computing environment. A fragment of the Semantic Web that determines the physical effects and trends of the domain is given in the work. In the analysis of emergency situations that occur in marine dynamic object exploitation, the functional elements of the knowledge base implement the dynamic structure, «Fields of Knowledge» and «Knowledge pyramids». Particular attention is drawn to the formalisation of the domain when dealing with navigability under the conditions of uncertainty and incompleteness of the initial information.
