摘　　要：本研究拟合了将线性评分转换为百分隶属度功能分的最优回归方程，采用Ｆｕｕｚｙ广义综合评判决策模型，确定了综合评判奶牛体型的模糊数学模型和计算机程序，其中各性状的权重分配用灰色关联度分析法研制。用此法对部分实测奶牛做的计算结果表明，该数学模型本身具有较高的灵敏度，评判结果与实际情况相符。The best regresson equation that can change Linear type scores to function scores of percentage was formulated,Generalized mathematic model and computer program of fuzzy synthetic judgment of multiple characters were determined.The power weight of every trait was worked out by grey relation analysis.The results calculated by using this method showed that the mathematic model had a higher sensitivity and the conclusion was correspond with the objective reality.
