| 摘 要： | 针对基于相似度的推理和合成关系推理存在的不足，本文提供一种将相似度量与贴近方向相结合，生成修正或诱导模糊关系的近似推理模式。通过引入模糊概念间贴近方向函数，构造扩展型和缩减型2类修正函数，由此导出推理模型的一般表达形式，并对几个修正算子和构造条件关系的模糊转化算子进行了分析比较。基于该推理模式构建焊接工艺决策模型，由给定熔深来确定合理的焊接规范参数，结果表明:模型可达到较高的计算精度，从而解决了近似推理中输出结果不能对输入事实的每一变化作出准确响应的问题。

| Abstract: | Based on the analysis of the characteristics of compositional relation inference and existing similarity reasoning, an approximate reasoning pattern is proposed, which combines the similarity measure and nearness direction to generate a modified (or induced) fuzzy relation. By introducing the function of nearness direction between fuzzy concepts, expansion-typed and reduction-typed modification operators are constructed. Accordingly, a general expression of the reasoning model is given, and the selection of some modification and translation operators for constructing fuzzy relations is discussed. The proposed method is applied to the decision-making of welding process parameters and determining reasonable parameters of welding codes with a given penetration depth. The experimental results show that the reasoning model has high computational accuracy, which will help in the accurate output results of approximate reasoning to every change in the input fact. |
