船舶动力装置设计方案的模糊综合评判

Fuzzy Comprehensive Evaluation of the Design Scheme for Marine Power Equipment

本文叙述了运用模糊综合评判方法,对船舶动力装置设计方案进行优选排序的基本原理与步骤。文中在对动力装置设计方案品质指标进行分类的基础上,着重分析了评判指标满意度和重要度的描述方法,并结合一算例,讨论了影响评判结果的因素。

By a fuzzy comprehensive evaluating method, the basic principle and procedure for the optimization and sequencing of the design scheme of the power equipment are discussed. Through the choice and screening of various factors which may influence the design, an index set is determined with a target tree. On the basis of the index analsis, a describing method for giving the degree of satisfaction of various indices is determined with assignment in stages. The operating procedure of the method is illustrated with an example and the factor that may influence the evaluated results is discussed.
