Based on the characteristic of ship investment, Indices of ship investment evaluation are established, which include economy evaluation index, invest chance expense evaluation index, and invest effectiveness evaluation index. Taken the pleasant degree as the objective function, established the multiobjective synthesis evaluation model of ship investment to evaluate ship invest considering the fleet as a whole, then to make decisions on vessel mould, tonnage, number, financing pattern. As to the economy index in the model presuming vessel chartered on voyage charter for the NPV index calculation, to simplify the converting complexity and the too much hypothesis influencing to the model outcome as always encountered before.
