摘要
首先给出具有外重域的非对称双枝模糊集的结构,提出以这种模糊集为基础的双枝模糊决策模型,详细论述了建模方法;然后给出决策中确定因素权重的二元对比方法;最后分析了模型的特性:双枝模糊决策存在定理,决策失效定理,双枝模糊决策挖洞原理和下枝决策的去余定理。具有外重域的双枝模糊决策模型是对工程中经常出现的一类决策模式的理论分析结果。
The paper first gives structure of non-symmetrical both-branch fuzzy sets with out-overlap domain, based on which a new model of both-branch fuzzy decision is proposed and modeling method is discussed in detail. Then, the method to make weight of factor in decision (duality in contrast method) is given. In the end, characteristics of model, which includes existence theorem of both-branch fuzzy decision, invalidation theorem of decision, caving principle of both-branch fuzzy decision and discarding redundance theorem in down-branch decision, are analyzed. Both-branch fuzzy decision model with out-overlap is the result from theoretical analysis for a kind of decision pattern usually arising in engineering.
