A Multi-Objective Model Study Of Emergency Supplies Distribution Under Natural Disasters

Entering the new century, science and technology are developing rapidly andpeople’s life is becoming better and better, but the developing also bring problems such asresources wasting and environmental degradation. It can’t be ignored that the naturaldisasters occurring frequently at home and abroad, which is a big thread to people’s lifeand property. It’s obvious that natural disaster has become an important factor restrictingour economy developing and society stability.This paper do the research about supply chain and logistic under natural disaster,establishing in the background of natural disaster. First, on the basis of relative research athome and abroad, the paper clears the concepts in the supply chain and logistic undernatural disaster, such as natural disaster, emergency supplies, emergency transit point,emergency logistic and so on. And then, the paper builds our country’s supply chain andlogistic network under natural disaster basing on the face of our country, with the help offoreign ones. Following, the paper choose a representative problem, emergency transitpoint locating and supplies distribution routing integrated problem to do the quantitativeresearch and build a multi-objective model. At last, the paper introduces the fuzzyprogramming method to solve the model and do the example research, which proveseffectiveness of the model and feasibility of the fuzzy method in multi-objective.The paper is aimed at summarizing the research about the supply chain and logisticunder natural disaster, and building a representative model for the key problem ofemergency commodity transit point locating and commodity distribution routing, which issolved by fuzzy method. It’s hoped that what the paper do will be meaningful to therelated national department and relevant researchers.
