Abstract Selection of shiptypes based on PSO group decisionmaking method with multiobjects was researched. First, at the foundation of multiobjects decisionmaking method which utilizes weighting distance to ensure the consistency of decision result, a new multischeme, multiobject group decisionmaking method was proposed. Then the individual evaluation value was adjusted by PSO, making the decision result keep the initial predilection of every expert and the fine consistency of interestrelevancies. And the new method was introduced to the process of shiptypes’ optimizechoice, then to determine the important factors and their weights, a series of shiptypes was generated by equality design, and numbers of experts were invited to make a strategic decision for achieving the decision result of best shiptype. This decision method offers a new simple and efficient avenue to optimizechoice of the shiptypes with high reliability.
