摘　　要：消防系统是保障船舶生命力的重要复杂系统。针对消防系统存在着失效不确定和失效路径模糊的问题,结合船舶的特点应用故障树建立了船舶消防系统失效模型。为了有效地避免故障树的计算量组合爆炸问题,采用二元决策图对该模型进行定性和定量分析。分析结果明确了系统失效路径,简便地得到了各失效因素的关键重要度,计算结果精确,并提出了相应措施来降低船舶消防系统失效的发生。Fire fighting system is an important complex system to ensure the viability of ships. According to failure uncertainty and failure path fuzzy of ship fire fighting system, a failure model of ship fighting system is set up based on falt tree analysis combining with the characteristics of ships. To avoid quantity assembled blasting problem effectively, the Binary Decision Diagrams （BDD） is used to analyze this failure model qualitatively and quantitatively. The analysis result identifies the failure paths and confirms the importance degree of failure .factors easily. The calculation results are exact and some corresponding measures are put forward to reduce failure of ship fire fighting system.
