| 摘 要： | 本文拟采用灰色关联分析方法，研究确定多性状模糊综合评判中因素“权重”分配的程序，运用于家畜体型外貌评定。通过１０头黑白花奶牛，用“评分法”、“灰色关联评判”和“多性状模糊综合评判”３种评定对比；说明用灰色关联度，隶属函数，进行模糊综合评判法，对家畜体型外貌鉴定是可行的。由关联度作归一化处理，所得“权重”分配集合，较用模糊数学确定隶属函数要简易，能客观地反映出鉴定意见的离散程度。对于“灰色关联评奖”

| Abstract: | Method of grey relation analysis was used in this paper to design an allotment program of factor power weight in the determination of fuzzy synthetic judgement of multiple characters and applied to animal judgings.
The contrast between the three assessment methods, i. e. scoring, grey relation judgement and multiple character fuzzy synthetic judgement] used with 10 Black and White dairy cows showed that it was possible to use grey relationship to determine subordinate function, in carrying out fuzzy synthetic judgement, and to judge livestocks. In comparison with the fuzzy mathematics in the determination of subordinate function, the grey relationship used in making normalized treatment, in which power weight obtained was collectively assigned, seemed to be more simple and could possitively express the dispersed degree of the judging opinion. Grey relation judgement (GRJ) is a direct method. It is simpler in calculation than fuzzy synthetic judgement, but with similar conclusion. With the same score or near the marginal difference scored between two classes given in the scoring method, the fuzzy synthetic judgement seems to be more efficient and beneficial to the development of animal judging technique. |
