Study on Architecture and Unified Model of Urban Emergency Response System

In order to meet the development demand of Urban Emergency Response System(UERS) in China,this paper designs a UERS model based on Unified Model Language(UML),which follows the mature modeling language standard of software engineering. The UERS model includes a decision-making of emergency command center,an emergency responding coordination center,dispatching centers of all cooperative units,the sub-branches of the cooperative units,execution divisions and sub-divisions. It can assist the system developers to regulate the development and software reusability of the system,optimize the system architecture,and accelerate the development of UERS.
