A Study on Development of Ship Economic Evaluation System Using ASMOD

Abstract

The aim of this paper is to build up the design model using ASMOD(Adaptive Spline Modeling of Observation Data) for the optimum scale of fleet, ship particulars and ship speed, etc. ASMOD, which define membership functions of fuzzy rule as B-spline basis function, represents a whole system as the sum of the sub-model. As it reduces the number of division of the space generated by the fuzzy set of input variables, it has a advantage of simplification to model structure and is efficient to represent the non-linear model. ※Keywords: ASMOD(적응형 스플라인 모델링), Fuzzy-neural networks(퍼지-신경망), Ship economic evaluation(선박 경제성 평가), LNG carrier(LNG 운반선), Optimum fleet(최적선단)
