考虑不确定性的保障设备设计方案决策方法

A Decision-making Method about Design Proposal of Support Equipment Taking Uncertainty into Account

研究了模糊性对装备的保障设备设计方案优选决策过程中的影响,基于模糊数学理论和灰色关联分析提出了一个考虑不确定性的综合决策方法,并建立了数学模型。该模型通过计算各保障设备的备选设计方案到正、负理想设计方案的模糊灰色关联系数,来确定各备选方案的相对优势灰色关联度,依据相对灰色关联度对各备选方案进行优劣排序,实现决策。通过某型机载装备的外场测试设备方案的立项竞标决策案例,对模型进行了应用。

The author researched into the influence of fuzziness on the optimum decision-making process of support equipment design proposal,proposed a comprehensive decision-making method based on fuzzy mathematics theory and grey correlation analysis.Taking uncertainty into account,and established a mathematical model.This model determines the relative superior grey correlation degress of every tradeoff design proposal through calculation of fuzzy grey correlation coefficients of every support equipment tradeoff design scheme,and sequences the tradeoff design proposals according to the good and the bad in accordance with grey correlation degree for realizing decision-making.
