改进的集对分析模型在煤与瓦斯突出评价中的应用

Application of Improved Set Pair Analysis Model in Evaluation of OutBurst of Coal and Gas

根据集对的原理和方法,引入接近度的概念对样本中的不确定信息进一步分析,建立了评价煤与瓦斯突出危险性的改进集对分析模型。对传统的同异反判别标准进行了改进,解决了样本中的某些指标值超出评价标准的问题。根据联系度函数理论上满足以真实突出等级为均值的正态分布,对评价结果进行定量化处理,进而提高了评价的精度。应用改进的集对分析模型对8个样本进行评价,通过与实际情况及其他方法的对比,发现应用该方法评价煤与瓦斯突出更加精确可靠。

Based on the principle and method of set pair analysis, the improved set pair analysis model is set up by introducing the concept of close degree. The problem of some value exceeds the evaluation standard is solved by improving the traditional criterion of SDC. The evaluation results are deal with by quantitative method based on the fact that connect degree function meet the normal distribution whose mean is real outburst degree theoretically, which improved the evaluation's accuracy. The model is applied in eight examples, compared with other evaluation methods and the actual situation, it is more accurate and reliable to use the improved set pair analysis model in evaluating of the outburst of coal and gas.
