Study on the action assessment for collision avoidance of trawling vessels with fuzzy pattern recognition method

Collision avoidance action assessment of single-trawling vessels using multilevel fuzzy pattern recognition model of the engineering fuzzy set theory was made. Compared with fuzzy comprehensive evaluation method, the results are similar. But the fuzzy pattern recognition method is more practicable and can save a lot of work in defining membership functions and, to a certain extent, eliminate the influence of subjectivity.
