基于模糊综合评价法的拖网渔船主机优选

Trawler main engine optimization selecting based on fuzzy comprehensive evaluation method

通过列举分析主机选型优化的各种方法,选取24 m拖网渔船作为研究对象,采用模糊综合评价法进行主机的优选.从拖网渔船的特殊工况出发,根据拖网渔船的工作特点,列出不同评价指标,经过评估来确定各项指标的权重,通过专家打分法和计算隶属函数的方法来进行模糊运算,根据最大隶属度原则进行模糊评判选择出最优主机,最后对结果进行分析验证并与其他主机选型方法对比,结果证明该方法可行且效果良好.

By listing and analyzing the various methods of main engine selection optimization,the 24m trawler was selected as the research object and the fuzzy comprehensive evaluation method was chosen for optimization.Starting from the special working conditions of trawlers,different evaluation indexes were listed according to the working characteristics of trawlers.The weights of each index were determined through evaluation,and fuzzy operations were carried out by expert scoring method and calculation of affiliation function.The optimal host was selected by fuzzy evaluation according to the principle of maximum affiliation,and finally the results were analyzed and verified and compared with other main engine selection methods.Results prove that the method is feasibleand hasgoodeffect.
