IMO stability regulations include various stability parameters such as GM values. To assess the stability of the ships, we should check all stability parameters of the IMO requirements. However, since this process is complex, a more convenient way to evaluate stability performance is required. In this research, the index for marine ship intact stability assessment (IMSISA) model was developed to solve these problems. The IMSISA model consists of a stability index calculation module and a stability assessment module. In the stability index calculation module, ten stability parameters, including GM, were used to develop the stability index, which has the advantage of being able to quantify the ship stability. The stability assessment module uses the stability index value to determine the stability status of the ship and provides the captain with stability management guidelines. To verify the proposed model, the basic stability calculations were performed for two model ships in 32 loading situations. The proposed model was found to provide better performance in the stability assessment than the previous study. By applying the IMSISA model to the ships, the captain can assess the ship stability more quantitatively and efficiently.

IMO稳定性法规包括各种稳定性参数，例如GM值。为了评估船舶的稳定性，我们应检查IMO要求的所有稳定性参数。但是，由于此过程很复杂，因此需要一种更方便的方法来评估稳定性能。为了解决这些问题，本研究开发了海洋船舶完整稳定性评估指标（IMSISA）模型。IMSISA模型由稳定性指标计算模块和稳定性评估模块组成。在稳定性指标计算模块中，使用了包括GM在内的十个稳定性参数来制定稳定性指标，其优点是能够量化船舶的稳定性。稳定性评估模块使用稳定性指标值确定船舶的稳定性状态，并向船长提供稳定性管理指南。为了验证所提出的模型，在32种装载情况下对两艘模型船进行了基本稳定性计算。发现所提出的模型在稳定性评估中比以前的研究具有更好的性能。通过将IMSISA模型应用于船舶，船长可以更定量，更有效地评估船舶的稳定性。
