动物品种优序决策的多层次模糊数学综合评判

A Multi-level Fuzzy Matheratical Synthetical Appraisal of Optimal Decision of Animal Breeds

为克服单层次的模糊综合评判产生结论不易区分、评价失效的缺陷,给出了多层次模糊综合评判的数学模型,结合动物品种优选排序研究,将众多因素剖分为若干子因素集,在单层次评判基础上,进行高层次的综合评判,获得了优选排序的研究结果.最后采用两种不同的模糊合成算子,映证了优序决策的同一性.

In this paper, a multilevel fuzzy mathematical synthetical appraisal of optimal decision of animal breeds is given to overcome the defect that the distinction of results is difficult induced by singlelevel one.
