摘　　要：在船舶设计优化中,设计变量或运营环境中存在的不确定性因素可能导致船舶性能无法达到设计工况的最优目标,甚至导致船舶因性能显著下降而使原设计方案失效。为了降低不确定性因素对船舶性能的影响,提高船舶设计方案在不确定性因素影响下的稳健性和可靠性,该文将不确定性设计优化方法引入船舶设计,构建了不确定性因素影响下的船舶设计优化数学模型及其求解流程,并将其应用于散货船设计优化中。优化结果表明:相较于确定性优化方案,不确定性优化方案更为优越,其稳健性和可靠性得到了显著提升。In ship design optimization,uncertainties in design variables or operational environments may prevent the ship performance from achieving the optimal objectives under the design conditions,and even lead to drastic performance deviations,causing the original design scheme to fail.The uncertainty-based design optimization method has been introduced into the ship design in order to mitigate the influence of uncertainties on the ship performance and enhance the robustness and reliability of ship design schemes.A mathematical model for the ship design optimization under the influence of uncertainties is established,along with its corresponding solution process.This method is then applied to the design optimization of a bulk carrier.The optimization results show that compared with the deterministic optimization scheme,the uncertainty-based optimization scheme is superior,and its robustness and reliability have been significantly improved.
