研究了城市防震减灾能力指标体系中指标权数的确定方法。首先用层次分析法计算了三个评价准则相对于城市防震减灾能力目标的权数和影响城市防震减灾能力的六大因素相对于每个评价准则的权数;在确定六大因素内部各指标权数时,主要根据震害经验、震害实例和专家经验,并举例说明了用层次分析法和影响度思想来确定五个生命线系统相对于整个生命线系统的权数,及供电系统中电力设备指标权数的确定方法。 The method to determine the index weight in the index system of earthquake resistance and disaster reduction in cities is studied. First, using AHP method to calculate the weight of the three evaluation criteria relative to the target of urban earthquake disaster reduction and mitigation capacity and the weight of the six factors that affect the capacity of urban earthquake disaster prevention and reduction relative to each evaluation criteria; in the determination of the six indicators In the meantime, we mainly use the experience of earthquake damage, examples of earthquake damage and expert experience, and give an example to illustrate the weights of five lifeline systems relative to the entire lifeline system by the analytic hierarchy process and the influence degree theory, and the indexes of power equipment in the power supply system How to determine the weight.
