摘　　要：引入不确定性优化方法,采用双层嵌套优化结构(外层采用改进粒子群算法,内层采用隔代遗传算法)对高速艇的总阻力目标函数进行优化.采用区间数描述航速摄动的不确定性,以改进的Michell积分为基础,以前半部分船体型值构成设计空间.算例证明了采用不确定性优化方法处理相关问题的有效性与优越性.Uncertainty optimization method was introduced,and double levels nested optimization structure（ IPSO algorithm was for outer layer,and IP-GA algorithm was for inner layer） was used to optimize the total resistance objective function of high speed vessel. Uncertainty of speed perturbation was described with interval number,and the design space was constituted by the hull former half part based on improved Michell integration. The example proves the effectiveness and superiority of uncertainty optimization design for the related issues.
