Aiming at the selection research gap of AG600 amphibious aircraft for salvage of life at sea, the selection index system of AG600 has been established, and an interval intuitionistic fuzzy selection decision model based on fuzzy entropy and score function is constructed. An evaluation index system with 8 indexes was determined based on the rules of the applicability, safety, and accessibility by questionnaire and statistical analysis. Different from the traditional method of determining the fuzzy number of each index solely by experts' scoring, this paper establishes a 5-grade fuzzy evaluation grade and index membership function, and the interval intuitionistic fuzzy number of the index is determined by combining subjective and objective methods. Fuzzy entropy and score function are used to calculate the weights of each index and AG600 selection score for different accidents, so as to obtain the matching degree of AG600 selection in marine life accidents more scientifically and reasonably. Finally, the effectiveness of the proposed model is demonstrated by a practical case.
针对 AG600 水陆两栖飞机在海上救援生命的选型研究空白，建立了 AG600 选型指标体系，构建了基于模糊熵和得分函数的区间直觉模糊选择决策模型。通过问卷调查和统计分析，根据适用性、安全性和可及性规则确定了包含 8 个指标的评价指标体系。与传统的仅由专家评分确定各指标模糊数的方法不同，本文建立了 5 级模糊评价等级和指标隶属度函数，通过主观和客观相结合的方法确定了指标的区间直觉模糊数。利用模糊熵和得分函数计算各指标权重和不同事故情况下的 AG600 选择得分，从而更科学合理地得到 AG600 在海上生命事故中的选型匹配度。最后，通过一个实际案例验证了所提出模型的有效性。
