RESUMO
In the rehabilitation stage of lifelines after earthquake, there would be no room for argument that people tend to experience various kinds of incovenience due to the functional failure of lifeline systems. However, we do not know yet the exact nature and degree of such incovenience people may experience during the lifeline functional failure. In order to make it the optimal the rehabilitation processes of lifelines after earthquake, we need to have some empirical data for the quantitative understanding of the incontinences. In this paper, we would like to present a model that describe the inconveniences due to lifeline functional failure based on the experiences by those who lived in Npshiro-city at time of 1983 Nihonkai-chubu earthquake.(AU)
