CONCEPT OF THE DECISION SUPPORT SYSTEM FOR CONTROL BY THE VESSEL MANEUVER IN CHANNELS

Abstract

The article discusses the problems and difficulties in the implementation of maneuvers, in particular, turning during movement of channels. The multifactorial nature of the external environment influences the complexity of perception and timely adequate analysis of the situation during the implementation of the turn maneuver. The newest developments of control systems considered in the article do not allow modeling the ship's movement in the canal with sufficient degree of adequacy, and as a result - there is no guarantee of keeping the vessel on the fairway trajectory planned by ECDIS. The concept of constructing a decision support system for the optimal choice of the maneuver control option for the movement of channels is proposed. The basis of such a system should be the knowledge base (KB) with the rules for the similarity of the conditions for the movement of channel turns for the correct choice of the developed data structure for control actions, both among the ready correct solutions and erroneous ones, to provide the operator with all the alternatives, their final result and the possibility of recording a new version of the solution. Attention is also turned to the structure of these external conditions. A search for a block type in a database (DB) is proposed to reduce time costs. Further filling the database and clarifying the rules of similarity of the KB will reduce the dependence of the security of the movement of channels on the human factor.
