Abstract:

A ship propulsion system is the major contributor to the occurrence of Ship Hull Vibration (SHV), which can easily lead to marine tragedies. Wrongly selecting ship propulsion systems will also significantly increase ship owners' operational costs. Based on a hierarchical structure for modelling propulsion systems, a subjective novel cost-benefit criteria analysis approach is developed to select the most economical propulsion system with the consideration of vibration characteristics. The weights of all the criteria are estimated by utilising an Analytical Hierarchy Process (AHP) technique. All the quantitative criteria in the hierarchy are converted into the qualitative criteria by proposing a novel approach. Membership Functions (MFs) of continuous fuzzy sets are employed to estimate the fuzzy performance ratings of all the criteria. By taking into account fuzzy performance ratings of all the criteria, a fuzzy Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) decision matrix is constructed. Finally, the most economical propulsion system, with consideration of vibration characteristics, is selected using the fuzzy TOPSIS method. The results of this paper reveal that the fuzzy TOPSIS is suitable for propulsion system selection.
