摘要:基于模糊推理、基于案例推理和基于规则推理是新型的问题求解方法。对于复杂问题很难用一种方法得到很好解决,哪种技术都存在理论和方法方面的缺陷,FBR、CBR和RBR和三种推理融合技术是解决复杂问题的有效方法。首先,对模糊推理、案例推理和规则推理的基本问题进行研究;然后,对“模糊+案例+规则”融合推理进行研究,FCR混合模式推理流程图说明了推理过程,并对推理步骤进行了详细说明。实际使用时要根据需要采用更高效的推理算法。

Abstract: Fuzzy-based reasoning, Case-based reasoning and Rule-based reasoning is a new method of problem solving. For complex problem difficult to solve with a method to obtain the very good, what kind of technology is of the defects in the theory and method FBR, CBR and RBR, and three kinds of reasoning fusion technology is an effective approach to solve complex problems. First, the Fuzzy -based reasoning, Case-based reasoning and Rule-based reasoning of the basic problems of research; Then, the " Fuzzy + Case +Rule" fusion reasoning, FCR blend mode inference flow diagram illustrates the reasoning process, and the deduction steps are detailed instructions. Actually use according to the need to adopt more efficient reasoning algorithm.

Key words: fuzzy-based reasoning; case-based reasoning; rule-based reasoning; fusion reasoning

推理是指由一个或几个已知判断推出一个新判断的思维过程。首先,推理是一种逻辑思维形式,是思维在人们头脑中的反映,是区别于感性认识的理性认识;然后,推理和判断不同,判断是对思维对象有所肯定或有所否定的一种思维形式,而推理可以由已知判断推出未知判断; 最后,推理是以客观事实以及客观事物之间的相互联系为依据,根据已知推出已知,没有客观事实为依据,也就不能称为推理。因此,推理过程需要一定的知识和经验,知识和经验丰富的人的推理结果更可信,推理也需要在一定的科学和技术的指导下进行。在人工智能领域,基于模糊推理技术(Fuzzy-based Reasoning,英文简写为FBR)、基于案例推理技术(Case-based Reasoning,英文简写为CBR)和基于规则推理技术(Rule-based Reasoning,英文简写为RBR)是新型的问题求解方法。其中,基于模糊推理技术是以模糊数学理论为基础,推理前提是模糊命题的逻辑组合,结论是表示推理结果的模糊命题,模糊命题成立的精确程度以隶属函数来表示;……
