FUZZY PRODUCTION MODEL FOR INITIAL EVALUATING OF THE RISK OF COLLISIONS
Abstract
Modern assessment of collision risk has a distinct value for safe shipping. Upon detection of a target vessel, that is, a vessel with which it is necessary to avoid collision, a ship driver shall promptly determine whether a situation of close approach to them is developing [1], and if it is so to decide on the best maneuver to prevent a possible threat.
This paper proposes a fuzzy production model of the initial assessment of collision risk on computed distance and time of approach, in which a mentioned disadvantage is eliminated.
Based on the theory of fuzzy sets an assessment model of collision risk is developed. Linguistic variables, used in it, are presented and universal sets for each of them are defined. Implementation of the model was carried out in a software environment FuzzyTECH, performance of the system on several test examples is demonstrated.
