摘　　要：为了更有效地分配燃油供给系统的可靠性指标,首先采用改进模糊层次分析法,根据模糊三标度的优先关系构建了影响燃油供给系统可靠性分配的5个因素的判断矩阵,确定了燃油供给系统故障易发的5个子系统对目标层的相对权重。然后根据综合权重对系统故障率进行分配,并由可靠度公式计算出各子系统应该分配的可靠度,计算所得结果与厂家实际统计结果相吻合,表明该方法是切实可行的,可应用于燃油供给系统的可靠性分配。For the more efficiently to allocate the reliability index of fuel supply system,it uses the Improved Fuzzy Analytic Hierarchy Process（ IFAHP） to construct the judgment matrix,determines the relative weight of failure-prone 5 subsystems of the fuel supply system,analyzes five factors of the reliability distribution of the fuel supply system. Based on three scales,it builds the judgment matrix and determining the relative weight of failure-prone 5 subsystems of the fuel supply system which is referring to the target layer. According to comprehensive weight,it can distribute the system failure rate and calculate the reliability of each subsystem. The results coincide with the manufacturers,the actual statistics provide a practical approach to reliability allocation of the fuel supply system.
