针对当前飞机结构的设计要求,建立了飞机结构安全的评价模型指标集,利用AHP方法提炼出4大类,14项具体指标,并确定指标权重,采用二元语义及其算子将评价语言值进行集结,对飞机结构安全进行评价.给出了评价步骤,并用实例说明该方法具有一定的可操作性,且合理可信. Aiming at the design requirements of the current aircraft structure, an indicator set of the evaluation model of aircraft structural safety is established. Four categories and 14 specific indicators are extracted by using AHP method, and the index weights are determined. The binary semantics and its operators are used to evaluate the language value Assembled to evaluate the safety of the aircraft structure, the evaluation steps are given, and an example is given to show that the method is feasible and credible.
