基于G1法的应急能力评估指标权重的确定

Weight Determination of Indexes in Evaluation of Emergency Response Ability Based on G1

在对城市应急能力评估前,确定应急能力评估指标的权重是重要问题之一。笔者介绍了一种无需一致性检验的方法G1法;分析并提出城市应急能力评估指标,通过实例利用该方法对指标在体系中的权重进行了计算。结果表明,在指标的数量较多的情形下,其计算量较其他方法明显减少,同时该方法的可操作性强,便于使用。

Prior to the evaluation of emergency response ability of a city, to determine the weight of each index in evaluating emergency response ability is of great importance. G1 method, a kind of method needless to test its consistence, is induced. After analysis, a set of indexes for evaluating emergency response ability of a city are proposed. Illustrated by a real case, the weight of each index in the system is calculated by this method. Result shows that when the number of index is numerous, the amount of calculation is reduced significantly. The method is easy to operate.
