摘要
分析了逻辑信息法的建模原理,并提出一个改进的数学模型.新模型中引进了标志的单调性概念.指出一个标志的单调性越佳,则对模型的贡献就越大,从而提高了模型区分各等级特性的能力,改善了模型的预测效果.文内举例计算评价了某超基性岩找矿前景,效果较好.
This paper makes an anlaysis of the modeling principle of Logical information method and putsforward an improved mathematical model in which a marked monotoncity concept has been incorporated. The better the marked monotoncity, the greater the contribution to the model, thus increasingthe ability of the model to distinguish the different grade characteristics and improving the prognosiseffectiveness. By using this new mathematical model a calculation and evaluation of the prospect foran ultiabasic rock belt has achieved a more better result.
