“…To date, only a few studies have modeled earthquake events of lifeline interrelations using system dynamics, which have attempted to quantitatively evaluate the impact on other lifelines by stopping the supply of one lifeline [3]. Although a part of the restoration process can be understood using this method, the model becomes more complicated when the interrelationship is explained as if the entire lifeline of the urban area is overlooked.…”

Although many studies have been undertaken in the area of lifeline interrelation, examinations based on the quantitative evaluation of post-earthquake lifeline interrelations have been limited. In this study, we present a new methodology to evaluate lifeline interactions, with an emphasis on the aspects of earthquake disasters. Terms related to other lifelines used in disaster reports are somewhat influenced by postearthquake behaviors. In this study, the number of related terms was counted, and the relationships between the lifelines were quantitatively assessed for the 2011 Tohoku earthquake that occurred in Japan. The validation process included checks through academic reports as well as government reporting. We found that many lifelines were strongly dependent on the electric power systems, which gave no consideration to the accident at the Fukushima nuclear power plant. We confirmed further that the similar lifeline interrelation results could still be obtained regardless of the reporting used.

In this paper the two analytical models which predict damage, post-earthquake restoration strategies and its period of water supply pipeline network are presented. The detailed model evaluates emergency restoration period of water supply pipeline network using the actual network data and the several restoration strategies that was provided from the experiences of past earthquakes. The simplified model also evaluates restoration period by strategy restoring from the side of distribution reservoir using the 1 km grid data of pipeline length of pipe type and diameter estimated from population data of reference area and water-supply pipeline expansion data. Using actual data of water supply pipeline network of three waterworks bureaus in Japan, we studies the accuracy of grid data of the proposed pipeline length modeling of the simplified model. Finally the efficiency and accuracy of approximate restoration period using the simplified model are confirmed by comparing with the results of two models about damage estimates and restoration periods.
