- 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.
