In case that port facilities are damaged by earthquake, their functional disorder have a bigger influence on various economic activities than roads because the former have higher and longer restoration cost and period than the latter.
Since very few previous studies had paid attention to those impacts, however, this paper proposes a method to estimate the earthquake damage costs of port facilities by defining them as the total amount of restoration costs of the damaged port facilities and the additional physical distribution costs due to the disorder of port facilities, for which the estimation techniques can be summarized as follows:
1) In order to estimate restoration cost and period of a berth, this paper applies a reggression analysis on the past experiences of various ports in Japan.
2) For estimating the damage cost in terms of physical distribution function of the port facilities, this paper builds a model of operations research type for the ships and cargos in the port.
3) By applying those models to a port, this paper checks the applicability of our model, and proposes a feasibility study technique of the anti-earthquake berth.
