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

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.
