典型环境条件下装备环境适应性的评估方法

Equipment Environmental Worthiness Evaluation Method in Representative Environmental Condition

系统分析了航空装备环境适应的特点及环境适应性要求的类型。在此基础上,根据装备的相关环境试验信息和外场环境故障信息,遵循确定模糊集隶属函数的原则,分别构建了描述装备对单因素环境适应性的隶属度。基于单因素评估结果,选择合适的确定权重的方法,确定模糊综合评判中各层次因素的权重。最后选择合适的合成算子采用模糊综合评估的方法分别提出了装备与下层产品的综合环境适应性评估方法。通过实例验证了模型的合理性和方法的可行性。

Characteristics and demand of environmental worthiness of aviation equipment were analyzed systematically.The membership functions describing environmental worthiness of equipment to single environmental factor were established according to the principle of determining fuzzy set membership function.Appropriate weighted method was selected to determine the weights of every environmental factor.Fuzzy comprehensive evaluation of environmental worthiness for equipment and its sublayer product was put forward,which was multilevel fuzzy comprehensive evaluation with synthetical operators.The rationality of the model and the feasibility of the method were validated with examples.
