The invention discloses a matching degree judgment method for a ship electric propulsion system design scheme, which comprises the following steps: firstly setting an index set of a propulsion system, then setting a decision set of the propulsion system, introducing an opinion set, carrying out fuzzy linear transformation on the opinion set, and setting the weight held by each index according to design requirements to obtain a fuzzy multivariate decision; and according to the maximum membership principle, determining that the propulsion system design scheme is optimal, good, medium and poor, and finally obtaining a matching degree judgment result. The method is proposed according to the characteristics of a ship electric propulsion system design scheme matching process and in combination with a fuzzy multivariate decision technology, and a matching degree judgment result is given according to a maximum membership principle or a score system so as to provide a decision basis.

    本发明公开了一种船舶电力推进系统设计方案的匹配度判断方法,先设定推进系统的指标集合,再设定推进系统的决策集合,引入意见合集并对意见合集进行模糊线性变换,根据设计要求对各指标所持权重进行设定得到模糊多元决策,按最大隶属原则,确定推进系统设计方案为优、良、中、差,最终得到匹配度判断结果。本发明是根据船舶电力推进系统设计方案匹配过程的特点,并结合模糊多元决策技术而提出的,匹配度判断结果根据最大隶属原则或分数制给出,以提供决策依据。
