　　The big earthquake on September 21, 1999 caused huge damage to Taiwan and made the government take this issue seriously again. Disaster prevention, protection, and reconstruction are the major topics of the hazard mitigation system. Protection means the emergency program after earthquakes, and how to distribute relief efficiency and effect is one of the key issues. From the optimization viewpoint, we constructed a relief distribution model using multiobjective programming methodology to solve this problem. Three objectives were included in the model – to minimize the total cost, total travel time, and to maximize the minimal satisfaction during the planning period. A blueprint was provided to illustrate what needs futher investigation in the future.
