平台供应船主推进系统综合评估方法研究

摘要

Taking the main propulsion of typical 9 000 HP PSV as example , the comprehensive evaluation approach of the main propulsion is investigated , so as to select optimal configuration of the main propulsion system .The evaluation indexes sys-tem is established by AHP which gains the weight vector .The membership functions carried out a description towards quantitative indexes .The quantitative indicators are obtained from the main propulsion configuration of PSV .The evaluation score is calculat-ed by fuzzy comprehensive evaluation theory .The numerical simulation results indicated that electric propulsion plant is the opti-mized system for PSV .The method is proved to be simple and practical .%以6580 kW（9000 HP）平台供应船为例，从众多的配置方案中选取整体性能最优的主推进系统。通过层次分析法建立评价体系的层次结构，获取各指标的权重向量；利用隶属度函数分析定性指标；依据所配置的方案，获得定量指标；运用模糊综合评价理论计算主推进系统的综合评分，计算表明平台供应船宜采用电力推进系统，该方法简单、实用。
