Efficiency Evaluation of Cockpit Based on Entropy Weight Fuzzy Analtic Hierarohy Process

对飞机座舱进行工效评估是飞机设计过程中的一个重要步骤,反馈结果能够进一步优化飞机设计。以减小工效评估过程中人为主观误差为目的,建立了基于熵权的模糊层次分析法评估模型。首先,将模糊数和判断矩阵引入;然后,建立了飞机座舱系统评估指标体系,并确定了基于熵的指标权重;最后,进行实例分析。结果表明,该模型能够有效减小主观误差,具有一定的实用性。

Evaluation of the cockpit is an important feedback step in the process of the aircraft design,which plays an important role in further optimization of aircraft design. To reduce the subjective error in the process of efficiency evaluation,an evaluated model was proposed based on entropy weight FAHP. Firstly,fuzzy number and judgment matrix is introduced;then mode of FAHP based on entropy weight is established,and weight is constructed;Lastly,example is analyzed. The results showthat this model can effectively reduce the subjective error and posses a certain practicability.
