The causes and effects of seismic disaster in an urbanized area were investigated with special emphasis on their functional impairment. There are two major problems when one tries to approach this very difficult task. They are (1) How to quantify the relation between a cause and an effect, and (2) How to clarify the inter-relational structures amony the causes and effects. In the early stages of the investigation, the Interpretive Strictural Modelling (ISM) and the Fuzzy Scvuctural Modelling were used to analyze the structures amoug the causes and effects, which had been identified by summarizing the results of the questiovaire survey to about 50 persons from various fields. However, during the course of the study, several drawbacks of these methods became clear, and a new method named "Fuzzy Quantitative Structural Modelling" I was developed.The new method was found to be very useful for the king of study under consideration in that it enables one to make more flexible interpretations of the cause-effect structure.

对城市化地区地震灾害的原因和影响进行了调查，特别关注其功能损害。当一个人试图完成这项非常艰巨的任务时，会遇到两个主要问题。它们是（1）如何量化原因和结果之间的关系，以及（2）如何阐明原因和结果之间的相互关系结构。在调查初期，通过对来自各领域的约50人的问卷调查结果进行总结，使用解释性结构模型（ISM）和模糊结构模型来分析因果关系的结构。然而，在研究过程中，这些方法的一些缺点逐渐显现出来，我开发了一种名为“模糊定量结构建模”的新方法。人们发现这种新方法对于正在考虑的研究非常有用，因为它使人们能够对因果结构做出更灵活的解释。
