表3 三级指标归一化结果

Table 3 Normalization results of three-level indexes

影响因素	突变模型	三级指标归一化
人员状况（A）	燕尾突变	$t_{A_{2}} = \sqrt[]{0.68} = 0.8246; t_{A_{3}} = \sqrt[3]{0.83} = 0.9398; t_{A_{1}} = \sqrt[4]{0.76} = 0.9337$
尾矿库本身状况（B）	燕尾突变	$t_{B_{1}} = \sqrt[]{0.92} = 0.9592; t_{B_{3}} = \sqrt[3]{0.81} = 0.9322; t_{B_{2}} = \sqrt[4]{0.76} = 0.9337$
安全管理（C）	燕尾突变	$t_{C_{3}} = \sqrt[]{0.70} = 0.8367; t_{C_{1}} = \sqrt[3]{0.80} = 0.9283; t_{C_{2}} = \sqrt[4]{0.75} = 0.9306$
环境影响（D）	尖点突变	$t_{D_{1}} = \sqrt[]{0.80} = 0.8944; t_{D_{2}} = \sqrt[3]{0.75} = 0.9086$
