何华灿等于１９９４年首次提出了数值化推理技术的概念，给出了一种基于规则矩阵的数值化推理算法，它同时完成规则的激活和可信度传播计算。本文提出另一种基于规则矩阵的数值化推理算法，它先判定规则是否被激活，再进行被激活规则的可信度传播计算。这两种方法各有优缺点，适用于不同场合，可根据应用需要选择 He Huacan et al. First proposed the concept of numerical reasoning technology in 1994, and gave a numerical reasoning algorithm based on a rule matrix, which completes the rule activation and calculation of credibility propagation. In this paper, we propose another numerical reasoning algorithm based on a rule matrix, which first determines whether the rule is activated and then calculates the credibility propagation of the activated rule. These two methods have their own advantages and disadvantages, suitable for different occasions, according to the application needs to choose
