针对围岩稳定性评判为典型的区间数多属性决策问题,将基于灰色系统理论的多指标灰区间数关联决策模型应用于围岩稳定性评判,以待评区域围岩稳定性指标数据和围岩稳定评判体系的不同等级数据构建多指标区间数序列,通过引入灰区间数序列的范数完成了多指标区间数决策矩阵的规范化处理,建立了多指标区间数整体逼近决策方法。实例结果表明,该模型有效、实用,为围岩稳定性评价提供了一种新方法。
Aiming at the problem of multi-attribute attribute decision-making of interval number with the stability evaluation of surrounding rock as a typical example, the multi-index gray interval number decision-making model based on gray system theory is applied to the stability evaluation of surrounding rock. Rock stability assessment system to construct multi-index interval number sequence. By introducing the norm of gray interval number sequence, the normalization of multi-index interval number decision matrix is completed and the overall approximation decision-making method of multi-index interval number is established. The results show that the model is effective and practical, which provides a new method for the stability evaluation of surrounding rock.
