摘要
本文根据实际地震预报中分析异常证据可信度的过程,提出了确定异常证据可信度的模型。指出异常证据的可信度可根据两类不同的影响因子(全局因子与局部因子)由证据可信度组合公式确定。据此在地震预报专家系统ESEP/PC中提出了“类框架”知识表示法。文中通过实例对应用中的有关问题进行了分析与讨论。
Based on the analytic process of anomaly evidence reliability in earthquake prediction practice, a model that can be used to determine the anomaly evidence certainty factor has been proposed in this paper. It has been pointed out that the anomaly evidence certainty factor might be delermined by the complete formula of evidence certainly factor in the light of two different effect factors (integrate factor and local factor) . Accordingly, a frame-like knowledge representation has been proposed in ESEP/PC. And the concerned problems when it is applied have been analysed and discussed through practical examples.
