Item DEVISING AN APPROACH FOR THE AUTOMATED RESTORATION OF SHIPMASTER’S NAVIGATIONAL QUALIFICATION PARAMETERS UNDER RISK CONDITIONS(2024) Ponomaryova, V.; Nosov, P.; Ben, A.; Popovych, I.; Попович, I.; Prokopchuk, Y.; Mamenko, P.; Dudchenko, S.; Appazov, E.; Sokol, I.The object of this study is the safety control system of ship management, by identifying and restoring the qualifica tion parameters of shipmasters in criti cal situations. The task solved in the study is the timely determination of an insufficient level of qualification for the perfor mance of certain operations in con trolling the movement of the ship, by applying a formal-logical model of de tecting the intuitive actions of the ope rator-shipmaster and gradually restor ing his/her qualification parameters using the devised method. The stages of development and the formal-logical structure of the model and method in terms of cognitive auto mation were described in detail as the study results. It was possible to ensure early detection of risks when controlling the movement of the ship in 56 % of cases, during a laborato ry experiment on simulators, which in 24 % of cases turned out to be particu larly dangerous. The interpretation of the results in volved algorithmizing complex and for malized data on the actions of opera tors and the application of the method of restoring their qualification para meters, which allowed a comprehensive approach to safety management. The distinguishing features of the findings were to predict the level of danger by simulating maritime opera tions with input navigational and indi vidual conditions. This made it possible to improve the effectiveness of ope rations to 89 %, reduce the phenome non of loss of control over the course to 32 %, reduce critical situations to 7 % and the cost of resources. The scope and conditions of practi cal use involve a comprehensive assess ment of external and internal influ ences on the level of danger, delay in decision-making by operators, as well as sailing conditions. The simulation results could be used to devise strate gies for planning maneuvers, predicting risks, and developing maritime securi ty systemsItem Formal Approaches to Identify Cadet Fatigue Factors by Means of Marine Navigation Simulators(2020) Nosov, P.; Ben, A.; Zinchenko, S.; Popovych, I. S.; Mateichuk, V.; Nosova, H.; Носов, П. С.; Бень, А. П.; Зінченко, С. М.; Попович, І. С.; Носова, Г. В.Contemporary marine education tends to have been using navigation simulators enabling cadets to be trained for any unlikely event. These issues are sure to be in the sector with high demand focusing on safety. Thus, they would be extremely beneficial for marine industry. The proposed study aims to identify seafarer fatigue during the maneuver carrying out according to circumstantial evidence and, as a result, the influence of this phenomenon on the trajectory formation of transition or maneuver experiences. In addition to it, the method of cadet posture identification is generally revealed. To summarize all this information exo – back spine and an automated system are proposed to be used. The study provides the mechanism formation of spatial trajectory taking into account the identification of fatigue indicators. This issue will, eventually, benefit into reducing risks of accidents. Besides, a formal description of perception and decision-making processes being performed by the cadet by means of modal logic and algebra of events are introduced in the preceding article. It is a basis for determining the stages and individual preferences in the formation of the trajectory transition (maneuver). To make ground, the experiment within the framework of analyses of the mooring operation carrying out is sure to be named an effective one. This article proposes comprehensive approaches and provides the possibility to classify models for the formation of the trajectory of the cadet in conditions of fatigue crack factors.
