Robust optimization model and algorithm of emergency establishment

In order to effectively choose emergency establishment in uncertain case, the weight interval estimation of emergency node was dealt with by using robust optimization method, the minimum weight distance between emergency establishment and emergency node was regarded as aim function, a choice model of emergency establishment in uncertain case was built, a solving arithmetic of the model was put forward, and the robust optimization result and the optimization choice result in certain case were compared.Comparison result shows that compared with the optimization function value, the windage of the optimization solution in certain case is larger than that of the robust optimization solution in uncertain case, so the model availably avoid risk.
