摘要： 利用与粒子群优化（PSO）算法相结合的多方案、多目标群决策方法对多种船型方案进行了决策优选. 首先在利用加权距离保证决策结果一致性的单方案、多目标决策方法的基础上，提出一种新的多方案、多目标群决策方法，然后引入 PSO方法对个体评价值进行迭代调整，使决策结果既能保持各位专家的初始偏好，又使各位利益相关者的意见具有良好的一致性. 将此决策方法引入船舶初步设计阶段的船型方案决策过程，分析确定船舶初步设计的重点属性指标及其权重，根据主尺度约束均匀生成系列船型方案，然后邀请多位专家进行评价决策，最终获得了船舶最佳主尺度决策结果. 该方法具有较高的可靠度，并为船舶主尺度方案优选提供了一种简便、高效的新方法.

Abstract: Selection of shiptypes based on PSO group decisionmaking method with multiobjects was researched. First, at the foundation of multiobjects decisionmaking method which utilizes weighting distance to ensure the consistency of decision result, a new multischeme, multiobject group decisionmaking 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 interestrelevancies. And the new method was introduced to the process of shiptypes’ optimizechoice, then to determine the important factors and their weights, a series of shiptypes was generated by equality design, and numbers of experts were invited to make a strategic decision for achieving the decision result of best shiptype. This decision method offers a new simple and efficient avenue to optimizechoice of the shiptypes with high reliability.  

Key words: group decision-making with multi-objects, consistency of decision, particle swarm optimization（PSO） arithmetic, ship-types&rsquo, optimize-choice
