In past seismic disasters, a lot of people had a difficulty to take a bath in their own house because of damaged homes and lifelines and got provided services at supporting bases. If the widespread disaster like Nankai earthquake happened, it may cause a large number of ‘disrupted-bathing people' in unprecedentedly wide area. It is important to predict the number of disrupted-bathing people and necessary amount of assistance for them broadly to plan the effective assistance. In this study, we had a case study in Okazaki city, Aichi pref. to estimate the number of necessary bases by mathematical optimization.
