Humanitarian Logistics Modelling for Flood Disaster Management in Thailand

Nowadays, many areas in Thailand have experienced severe flood disasters that have widespread effects on life, property, society, economy, and the environment. Therefore, this research aims to develop a mathematical model for humanitarian logistics management in Thailand's flood-affected areas. Two models were developed using mixed-integer nonlinear programming: one to minimize the total cost of disaster relief management, and another to maximize the number of rescued disaster victims, with operating costs as a constraint, because in some situations there was a limited budget for helping victims. The two proposed models provided disaster preparedness planning by identifying optimal shelter locations, determining appropriate quantities of relief supplies to procure, and allocating and distributing those supplies efficiently to affected victims.
