摘　　要：为评估高原库区施工船舶安全并预警,构建基于三角模糊层次分析法的综合评价模型。运用三角模糊层次分析法确定各层指标权重,充分考虑各因素相对重要性比较中的模糊性。采用正态分布隶属函数确定最低层指标隶属度,运用模糊数学对专家评分进行模糊化处理,使得确定的隶属度更加真实可信,最终评价结果也更准确可靠。以此模型为基础设计基于VB.net语言的船舶安全预警系统软件,并用实例验证其科学性、合理性和实用性。To evaluate the safety of construction ships in the plateau reservoir area and give early warnings,a comprehensive evaluation model based on the triangular fuzzy analytic hierarchy process is built.The weights of indicators on each level are determined by the triangular fuzzy analytic hierarchy process,where the fuzziness of relative importance comparison between factors is considered fully.The membership degrees of the bottom indicators are determined with the membership function of normal distribution,and expert scores are blurred by the fuzzy mathematics,which makes the determined degree of membership more authentic and credible,and the final evaluation results more accurate and reliable.Based on the model,the ship safety early warning system software is designed by VB.net language,and its scientificity,rationality and practicability are verified by examples.
