摘　　要：航空电子综合系统是作战飞机的神经中枢,准确评估航电系统的效能对我国航空电子技术的发展具有重要意义。为了用灰色白化权函数聚类法对基于1553B总线的航电系统进行效能评估。首先将1553B总线负载、延迟时间、总线使用效率三项指标分为优、良、中、差四个灰类,综合各指标的白化权函数和其隶属于不同灰类的权重得到航电系统聚类系数向量,然后由该向量中的最大聚类系数所属灰类来确定该航电系统的灰类等级。灰色白化权函数聚类方法为航电系统的设计和效能评估提供了重要方法和理论依据。Avionics integrated system is the nerve center of combat aircraft,to accurate evaluate the effectiveness of avionics system means important for Chinese aviation electronic technology.In this paper,gray whitening weight function clustering method was used to evaluate the avionics system based on the 1553B bus.The 1553B bus loads,delay time and bus efficiency were divided into four gay classes such as excellent,good,fair and poor.The whitening weight function of each index and the weights of different gray classes of each index were usd to get avionics system clustering coefficient vector.Then the avionics system gray types were determine by the gray class of largest clustering coefficient.The method provides an important method and theory basis for the avionics system design and performance evaluation.
