VLCC加装压载水管理系统设备选型

Selection of Retrofitted Ballast Water Management System for a VLCC

针对船舶压载水管理系统(Ballast Water Management System,BWMS)设备选型的多样性和复杂性问题,以运营的超大型油船(Very Large Crude Carrier,VLCC)为研究对象,分别采用层次分析-逼近理想解排序法和模糊层次分析法对BWMS进行设备选型研究。结果表明,采用这2种方法得到的最优方案结果一致,2种方法都适于对VLCC进行BWMS设备选型,但对于没有实际数据,只能通过专家评判得到数据的这类设备的选型而言,采用模糊层次分析法的效果优于层次分析-逼近理想解排序法。

To deal with the problem of diversity and complexity in selecting ship Ballast Water Management System(BWMS),this paper takes a Very Large Crude Carrier(VLCC)in service as the research object to study the selection of BWMS using the Analytic Hierarchy Process-Technique for Order Preference by Similarity to an Ideal Solution(AHP-TOPSIS)method and the Fuzzy Analytic Hierarchy Process(FAHP)method,respectively.The result shows that the optimal solutions given by the two methods are identical,and both are suitable for VLCC’s BWMS selection.However,when there is no actual data and the selection can only be accomplished according to expert’s evaluation,the FAHP method is superior to the AHP-TOPSIS method to approximate the ideal solution for the selection of such equipment.
