Fishing capacity evaluation of fishing vessel based on cloud model

Abstract In the evaluation problem of fishing vessel fishing capacity, the imperfect evaluation index system and the methods of evaluation indexes are mostly artificial qualitative evaluation methods, which lead to strong subjectivity and fuzziness as well as low accuracy of evaluation results.Therefore, this study introduces cloud model theory on
