在基于CFD的船型优化中，采用参数化方法对船体进行精确表达时，大量船型参数带来了计算成本和时间成本问题。而敏感度分析可通过分析各参数对船舶性能的敏感性，降低设计空间的维度，节约成本，并对后续的船型优化具有指导意义。但迄今为止，敏感度分析在船型优化中的应用相对较少，与其相关的研究仍不充分。在梳理现有成果的基础上，对敏感度分析方法及其在船舶及船型优化领域的国内外研究现状进行综述，提出尚需解决的问题，指出发展方向，旨在为敏感度分析在船型优化领域的进一步发展提供参考。
In the optimization of hull form based on CFD, when parameterization is used to express the hull accurately, a large number of hull parameters bring the computation cost and time cost. Sensitivity analysis can analyze the sensitivity of various parameters to ship performance, reduce the dimension of design space, save cost, and has guiding significance for the subsequent ship optimization. But so far, the application of sensitivity analysis in ship type optimization is relatively less, and the related research is still inadequate. Based on the existing achievements on carding, this paper summarizes sensitivity analysis method and the status quo of research on sensitivity analysis in ship and ship optimization field at home and abroad, put forward the problems, and points out the direction of development, in order to provide reference for the further development of sensitivity analysis in the field of ship optimization.
