Abstract: | A method is presented for selecting a preferred ship from a group of candidates as a reference ship for a new design. The
method is based on a recently developed approach for multiple-criteria decision analysis under uncertainty, the evidential
reasoning approach. Using this method, both quantitative and qualitative attributes of a complicated nature can be considered
in the selection process. The method consists of three phases: identifying suitable candidate ships, evaluating them in terms
of both conventional techno-economical and qualitative attributes, and aggregating all the attributes using the evidential
reasoning approach. This three-phase procedure is illustrated by means of an oil tanker selection example. The results of
this study show that the evidential reasoning approach can support multiple-criteria ship selection processes when both qualitative
and quantitative information with or without uncertainties have to be taken into account. The outcomes generated by the method
include the ranking of the candidate ships and indications of their strengths and weaknesses in the format of performance
distributions over different assessment grades. Such information is vital in helping decision makers to make an informed selection
and be aware of any risk implication associated with the selection. |
