摘要
本文通过对矿床评价知识领域的特点进行分析,讨论了矿床评价专家系统中,在多条规则具有相同结论的情况下,各规则前题的相互关系及根据各规则得到的共同结论的各后验概率值的相互关系,提出了一种根据全部具有相同结论之规则,求共同结论的最终后验概率值的算法,并对计算结果的合理性进行了论证。
This paper, by analyzing the characteristics of the ore deposit evaluation-related knowledge, discusses the relationship of the presuppositions of all rules which have a common conclusion and the relationship of the common conclusion's posterior possibilities gained from the rules, and puts forward a new method of calculating the common conclusion's final posterior possibility based on the common-conclusion rules and verifies the Yationality of the calculaled result.
