【摘要】 本文提出一种基于模糊类推推理的复杂系统定性建模的算法。基于模糊逻辑和类推推理相结合,定义了信息含量更高的知识表示的模糊定量空间,并发展了以输入输出空间中模糊集相对位置的距离为依据进行类推得出结论的算法。该方法一方面基于类推推理的理论,同时又可把启发性知识加入到结论中,对复杂系统在不精确、不完备的信息下进行建模提供了一种方法。更多还原

【Abstract】 A method on qualitative modeling in complex system is presented. Based on the combination of fuzzy logic and analogical reasoning, fuzzy quantity space is defined to represent a more informative representation of knowledge and a distance measure is used to measure the relative position between two fuzzy sets so that we can analogize the conclusion. Finally the heuristic knowledge can be added into the derived conclusion to more suit to the real application.更多还原
