MATHEMATICAL DESCRIPTION OF THE QUANTITATIVE ASSESSMENT OF DECISIONS MAKING BY THE NAVIGATOR

Abstract

The content of the paper belongs to the field of interdisciplinary scientific research, which lies at the intersection of cognitive psychology and navigation, and is devoted to the topic of decision-makings by a navigator that is relevant for navigation. The results of the author’s theoretical research on the formalization of some aspects of human mental activity and their representation in practical implementation for solving problems of navigation are reflected in the paper. The human factor is a complex multidimensional problem that covers the entire spectrum of human activities at sea. Only a small part of this problem is described in the paper, which is of a debatable theoretical nature. The specificity of the study is that the navigator is, first of all, a person who makes not just decisions, but decisions with sense. Therefore, the navigator inclusion into the ship control link leads to the need to simultaneously take into account the navigator psychological characteristics, his ability to make meaningful decisions, and the characteristics of the ship controllability as an object of control. At the same time, the decisions made by the navigator are subjective and difficult to formalize. The purpose of the study is to formalize, i.e., to describe mathematically the quantitative assessment of decision making by the navigator.To calculate the amount of meaning in the decisions made by the navigator, the method of probabilistic evaluation of the sense in a text message is used. A model in the form of a semantic prism is proposed as a structure of the semantic space where the navigator makes decisions. The results obtained on a practical example are adapted to the concepts of navigation and therefore may be of interest to specialists in ship traffic control automation, artificial intelligence, creation of intelligent control systems and navigation safety.
