Abstract
Contribution of the local construction industry is essential to elimination of road obstacles and repair work of the early period of disaster by severe earthquake. However, in late years, the number of construction machine possessed by constrruction companies tends to decrease by intensification of the competition by a decrease in public construction and the change of bidding method. Minagawa and others examined how rubble processing can be efficient by the cooperation of sorrounding regions in case of Tokai earthquake occures.
In this article, the authors added the construction machines possessed by lease work corporations and estimated the amount of the rubble produced by an earthquake stood on the East Japan great earthquake disaster. Influenece of construction machine distribution for the effectiveness of rubble processing were discussed based on the simulations with Multi Agent Technology. As a result, it was confirmed that the distribution of the construction machines including leased machines affected the duration to remove the rubbleand especially the initial placement of the leased machines should be estimated properly.
