Application of fuzzy analysis technology in ship navigation safety characteristic evaluation system
It is difficult for traditional methods to comprehensively consider all factors during ship navigation.In this paper,fuzzy analysis technology and adaptive weighting algorithm are applied to the evaluation system of ship navigation safety characteristics.The structure of the evaluation system is designed,the adaptive weighting algorithm is designed in de-tail,and the weight changes of the secondary index of ship structural stability under different wind levels are given.Fuzzy analysis method is used to evaluate navigation safety characteristics,and the process of fuzzy analysis is determined,includ-ing determining membership function,fuzzifying input data,formulating fuzzy rule base,fuzzy reasoning,and fuzzifying.The research results of this paper have important practical significance.
