The DHT model was developed for estimating number of <br>days required for disaster waste disposal, following parameters are mandisopdatory as the model inputs; (1) <br>disaster waste characteristics (distributions, volume and contents) in damaged area, (2) hauling/transportation <br>route, (3) number/capacities of transportation vehicles, (4) maximum capacities at temporary storage / final <br>disposal sites and (5) abilities of crushing/classification equipment. Almost all parameters were set by referring <br>to a planning document of disaster waste disposal provided by Wakayama city and disposal guidelines <br>published by Ministry of the Environment of Japan. Several parameters without description in these <br>document/guideline, e.g. maximum capacities at temporary storage and distance of hauling/transportation route <br>were estimated by using GIS. Severe shock and tsunami caused by Nankai Trough huge earthquake were <br>adopted as external forces generating disaster waste. By assumption that parameters included in (3) and (5) <br>could be critical parameters for a result of simulation, we performed sensitivity analysis of each parameter in <br>them. As a result, abilities of several crushing / classification at temporary storages were the most sensitive <br>parameters of all evaluated parameters. Therefore, augments of crushing/classification functions at temporary <br>storage might be effective to shorten processing days for disaster waste disposal</p> ER -
