模糊综合评判法在船舶主机选型中的应用

Application of Fuzzy Comprehensive Judgment on Choosing the Main Engine of Ship

综合考虑船舶主机选型时对主机的经济性影响较大的五个因素,即主机初投资、燃油耗率、可靠性、重量、尺寸等,作为判断主机经济性优劣的指标。运用模糊综合评判理论对可供选用的主机进行评判,论证并确定最合适的主机。通过在某1400TEU集装箱船主机选型上的应用,结果表明,该法可行且效果良好。

Comprehensively considering the five factors which impact on economic of main engine when choosing the main engine for the ship, such as initial investment in purchase, rate of fuel consumption, reliability, weight and size, regard the five factors as a standard of judging the economic of ship main engine. Using the theory of fuzzy judge choice some main engines, then study and identify the most suitable main engine. It has demonstrated the feasibility and good efficiency of the method after applied for the main engine choosing in one of 1400TEU container.
