摘　　要：舰船设备抗冲击性能是舰船生命力设计的重要内容。基于模糊数学的基本理论,引入炸药当量、爆距、炸药方位、设备相对位置和抗冲击能力等因素作为基本评判参数,构建舰船设备抗冲击生命力评估的数学模型,按层次分析法确立各参数的权重系数,确定各参数隶属度函数,实现对水下爆炸载荷作用下舰船设备生命力的模糊综合评判,提出舰船设备生命力的评判方法。Anti-shock behavior of equipments on board the naval ship is a critical characteristic of the survivability. Rational assessment may assist to obtain a timely, reliable prediction of anti-shock behavior in the war time. The study is conducted on the methodology for assessing the survivability of the shipboard equipments based on the theory of fuzzy comprehensive assessment. A numerical model is established by incorporating the factors, such as quantity of detonator, explosion range, blast azimuth, relative location of equipment and anti-shock ability, as the basic parameters for survivability assessment. The priority trade-offs for each parameter is identified using analytical hierarchy process, and attribute function is determined. Therefore, fuzzy comprehensive assessment of anti-shock ability of shipboard equipments subjected to the explosion load is achieved. This method for assessing the survivability of shipboard equipment is put forward.
