The Human Navigation Element as a Statistical Parameter in the Information Aspect

Abstract

The paper presents the results of a study on the topic of the human element in navigation, which is relevant for sailing. The relevance of the topic lies in the fact that this factor has a predominant influence on the safety of navigation. The main approach to the study of the human element is a psychological approach. This study uses the cybernetic approach based on concepts of the information theory, such as entropy. The object of the study is a complex dynamic control system, the main elements of which are the master, the vessel and the object of maneuver. The subject of the study is the human element of navigation in the Poisson notation, as the main determinant of a probabilistic state of the control system. The purpose of the study is to develop a probabilistic model for normalizing the human element of navigation from the standpoint of the cybernetic approach and a Poisson distribution of the random variable. The main hypothesis of the study is that the intermediate points of the trajectory of movement are the points at which the navigator makes decisions on controlling the movement of the vessel. The frequency of these points depends on many random reasons, including the human element. As a result of the study, the notion of the human element of navigation was formulated in the Poisson notation, and an evaluation criterion for the probabilistic state of the control system was proposed. The results are recommended to researchers in the field of automation of ship traffic control and specialists in creation of intelligent systems for controlling the movement of a marine vessel.
