为了更好地对产品的可达性进行评估,提出了一种飞机可达性改进评估的方法。首先界定了可达性的内涵,提出了“可达性改进”的概念,给出了“可达性满意度”的概念及测量方式;其次构建了可达性约束集模型,并应用Bayes估计模型对产品的可达性满意度进行评估,确定是否需要改进及改进方向。最后,以某型飞机的发动机为例,分析了可达性改进评估的过程。

A method for evaluating aircraft accessibility improvement is put forward to make better evaluation of accessibility. First,the connotation of accessibility is defined,the concept of “accessibility improvement” is put forward,and the concept of “accessibility satisfaction index” and its measurement mode are offered. Then,a constraint set model is built up for accessibility of aircraft,and the accessibility satisfaction index is evaluated by using Bayes evaluation model in order to confirm whether it needs to be improved and its improvement orientation. Finally,taking the engine of a certain type of aircraft as an example,the process of evaluation on accessibility improvement is analyzed.
