摘要
多指标等级评价目前一般采用定性评判,运用灰色系统中的灰靶分析,可以对其进行定量评价, 以岩体稳定性分级为例介绍了评价多指标等级的灰靶分析法,经数据算例验证是可行的、合理的。该方法与灰色关联分析法相比计算简便,计算量少。
Qualitative evaluation is usually adopted in multi - criteria grade estimation and quantitative inheritance can be put in through grey target analysis of grey system. As is instanced by stability grading of rock mass, grey target analysis on multi - criteria grade estimation is proved feasible and reasonable. Compared with grey relational analysis, it is easy to conduct and of less calculation quantity.
