Application of fuzzy set pair analysis on evaluation of seafarers' competency

摘要

In order to evaluate and analyze the seafarer's competence scientifically and objectively, an evaluation model of seafarers' competency based on fuzzy set pair analysis is proposed. By considering both definition of `marine resource management' by IMO and the current research status of crew assessment in China, the evaluation index systems are established for the two kinds of seafarer. In the evaluation process, to bring the uncertainty of evaluation data, the fuzzy connection degree is used to express the fuzzy relationship of similarities and differences between the evaluation object and the evaluation standard. The evaluation results show that the model can evaluate the seafarer's competence for different grades of crew reasonably, and find the main factors affecting the competency. By comparing with the comprehensive evaluation method, the fuzzy set pair analysis is more accurate and scientific.
