基于端点梯形白化权函数的飞机保障性灰色评估

保障性评估是提高飞机保障性的有效手段。从保障性的定义出发,构建了飞机保障性评估指标体系,在利用层次分析法(AHP)确定指标权重的基础上,对三角白化权函数进行了改进,建立了基于端点梯形白化权函数灰色评估模型,很好地解决了相邻的若干类别对该类别聚类中心的影响问题,并将其应用于飞机保障性的评估,通过实例分析,验证了此评估方法的可行性,对提升飞机保障性评估的准确性有一定的参考价值。

Study on Gray Evaluation of Airplane Supportability Based on Trapezoid Whiten Weight Function of Endpoint

The evaluation of supportability is an effective method to raise supportability of airplane. From the definition of supportability,the paper structures supportability evaluation index system of airplane based on the determination of weight coefficient of index by using AHP. Gray evaluation based on trapezoid whiten weight function of the endpoint is established by improving triangle whiten weight function. The model provides a good solution to the problems of influence from adjacent several categories to clustering center,and it is applied to the evaluation of airplane supportability. Through instance analysis,the paper testes and verifies the feasibility of this evaluation method. It has great reference value to promote the veracity of evaluation of airplane supportability.
