A Network Model Research for Emergency Supply Database

For the question that how to show the emergency supply in the software, a mathematical model is developed in this paper. The mathematical model distinguishes connecting sides, nodes from different networks, which includes modeling events as material information, information of transporting vehicles, scheduling schemes, and disaster points. Then according to requirements of the modeling elements and relationships between different modeling elements, the constraints are established. At the end, we developed software which can show the mathematical model is reasonable.
