摘　　要：针对复杂网络理论研究电网节点脆弱性时存在的局限性,在考虑舰船电力网络结构脆弱性的基础上,将源与负载间连接路径的可达性叠加到舰船电网的综合脆弱性中;利用多属性决策方法,提出基于主客观赋权法相结合的综合权重自适应获取模型。首先,将舰船电网结构脆弱性和物理脆弱性相结合,提出综合脆弱性的概念;其次,选取层次分析法和熵法这两种典型的主、客观赋权法,利用加权和法的评价函数作为优化模型的目标函数,提出自适应综合权重获取的优化模型,实现对舰船电网综合脆弱性的全面评价;最后,将所提综合脆弱性指标与传统结构脆弱性指标相比较,通过某环形舰船电网验证了模型的有效性。Aiming at the deficiencies of node vulnerability assessment based on complex network theory, an adaptive model based on muhi-attribute to assess node comprehensive vulnerability of shipboard power network is proposed. First, the structural vulnerability and physical vulnerability was considered, and the concept of comprehensive vulnerability is able to overcome the existing inadequacy of social network index and system science index. Then, the entropy theory and AHP were applied in comprehensive evaluation model, and information of objective data and subjective opinion of experts were combined in the model to implement effective evaluation. Finally, the comprehensive vulnerability index was compared to traditional structural vulnerability index. The test on a ring shaped shipboard power network demonstrates the validity of the model.
