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. It is of great significance to evaluate the effectiveness of avionics system to the development of avionics in our country. In order to use gray whitening weight function clustering method based on 1553B bus avionics system for performance evaluation. First of all, the 1553B bus load, delay time, the bus efficiency is divided into three indicators of excellent, good, medium and poor four gray, the indicators of the whitening weight function and its weights belonging to different gray to get the avionics system poly Class coefficient vector, and then determine the gray level of the avionics system from the gray class to which the largest cluster coefficient in the vector belongs. Gray albino weight function clustering method provides an important method and theoretical basis for the design and performance evaluation of avionics system.
