COORDINATION OF TECHNICAL AND BIOLOGICAL SEGMENTS OF THE ERGATIC SYSTEM "SHIPMAN - SHIP" USING A FUZZY NEURAL NETWORK APPROACH

Abstract

The article analyzes the causes and consequences of dangerous situations during the movement of the vessel and determines the need for an individually adapted approach to support decision-making. An approach is proposed for the operational control and support of the boatmaster's actions, which is based on the use of an individually adapted neural network model of his activity, implements the features of managerial reactions in hazardous sailing modes. Such models make it possible to identify and intercept the boatmaster's errors in the process of implementing the decision. Predicting the accuracy of bringing the vessel to the terminal point of the maneuver trajectory based on the current state vector, ensures the timely determination of the situation. The complexity of the problem of predicting situations in dangerous control modes due to the determination of the navigator's errors arises from the impossibility of clearly stating the correspondence of changes in the input and output parameters of the state in which the control object is located or to which it seeks. The most important property of fuzzy neural networks, which indicates their great potential in predicting and supporting the actions of the navigator, is the possibility of parallel processing of information by all neurons. Due to this ability, with a large number of interneuronal connections, processing of a significant amount of measurement information, incoming measurement information in real time is achieved simultaneously. The structure and parameters of fuzzy neural network models are determined based on the processing of data from previous actions performed by a specific boatmaster on a specific ship, and are continuously updated as new data arrives. The classification of the navigator's errors when making decisions in the process of managing ships was used, which made it possible to develop procedures for responding to them. The proposed approach makes it possible to coordinate the technical and biological segment of the "boatmaster судов ship" ergatic system and to reduce the influence of the human factor in dangerous situations during the movement of the vessel.
