基于Fuzzy推理的鱼病诊断专家系统

Fish disease diagnosis' expert system based on Fuzzy reasoning

鱼病诊断过程中存在大量的Fuzzy性问题,通过对三I算法的分析,提出一个基于RM蕴涵算子的三I算法,并就FMP(fuzzy modus pronens)问题,运用该算法,研究基于多维,多重以及多维多重规则时的解。该算法在研究鱼病诊断系统的过程中结合鱼病专家知识库,提取出鱼病诊断规则,抽象出鱼病诊断Fuzzy推理的一般性模型,并给出了基于该模型的算法,在该算法中,应用的Fuzzy推理是基于RM算子的三I算法。

We advance an improved three implication reasoning algorithm based on RM arithmetic operators. As for FMP （fuzzy modus pronens） problem, we provide the solution for multidimensional, multiple and multidimensional and multiple rules with this algorithm. And we theoretically analyze its compute performance, and think it more excellent than general three implications reasoning one. In the end, on the basis of analyzing the characters of fish disease diagnosis and communication with fish disease expert, we extract the rules for fish disease diagnosis , put forward a general model for fish disease fuzzy diagnosis and show up our algorithm for this model. In our algorithm fuzzy logical reasoning that we used is just the three implication reasoning based on RM arithmetical operators we advanced.
