A bi-objective evacuation routing model with secondary evacuation expected costs

摘要：

The recent nuclear leakage accidents have made evacuation a leading issue in emergency management. Evacuation routing is one of key problems for helping people move to safety. In this paper, a bi-objective model is proposed to optimize the route assignment, with the possibilities of secondary evacuation in consideration. This model is aimed to minimize the maximum travel time and minimize the secondary evacuation expected costs simultaneously. An approximation algorithm with polynomial complexity is designed to solve this model. Finally, a numerical example is given to demonstrate the actual significance of our model and the validity of this algorithm.
