Inter-ward, Risk-diversified Allocation Model for Storing of Disaster Relief Goods

This study focuses on the concept of an inter-ward, risk-diversified spatial allocation model for the storage of relief goods to reduce the cost of the relief goods policy. The study proposes the model, and shows the feasibility and efficiency of the suggested logistics policy by applying it to a case study of the Shonai River, Nagoya City. The simulation results show that one day’s worth of stocked relief goods in each shelter is sufficient for sustaining all evacuees for three days in any disaster scenario, and reduces the total costs of the relief goods policy. The study further illustrates the applicability of the model to wide-area disasters.
