摘要
城市防震减灾工作关系到经济建设和社会发展,科学合理地对城市承受地震灾害的能力进行评估并有针对性地加强其薄弱环节,是减轻城市地震灾害的有效方法之一。根据影响城市防震减灾能力的主要因素,在设定多层次指标体系基础上,将层次分析法(AHP)用于城市防震减灾能力的评价体系中,其中考虑了信息不全的AHP和不确定的AHP,该方法将复杂的问题分解成若干层次,在比原问题简单得多的层次上逐步分析,从而达到解决问题的目的。
Cities＇ ability reducing earthquake disasters is a complex system involving numerous factors, moreover the research on evaluating cities＇ ability reducing earthquake disasters relates to multi-subject, such as earthquake science, social science, economical science and so on. In this paper, the fragmentary AHP （analytical hierarchy process） , and the indeterminate AHP was used to assess the cities＇ ability reducing earthquake disasters. The AHP easily solves the problem by reducing the complex object to several parts. It can evaluate cities＇ ability reducing earthquake disasters absolutely and quantitatively and consequently instruct the decision-making on reducing cities＇ earthquake disasters loss.
