摘　　要：结合船舶电力系统递阶层次结构,建立了船舶电力系统的脆性结构模型,该模型分为脆性风险层、系统结构层、脆性事件层和脆性因素层.在该模型基础上,提出了一种基于层次分析法的船舶电力系统脆性分析方法,通过定量计算系统脆性结构模型中各层元素对系统总目标的合成重要度系数,找出最容易导致船舶电力系统脆性发生的脆性因子,从而为预防船舶电力系统脆性发生提供了计算依据.Combining with recursion order hierarchy structure of ship power system, brittleness structural model is constructed which is divided into four layers, that are brittleness risk layer, system structural layer, brittleness event layer and brittleness factor layer. The analytic hierarchy process（AHP） is applied to analyze brittleness of ship power system based on the proposed brittleness structural model, through quantitative calculation of synthetic importance factor coefficient of elements in every layer to overall objective, the brittleness factor most easily causes brittleness of ship power system is found out, that can provide computation basis for preventing happening brittleness.
