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