Research on Regional Emergency Logistics Center Location Based on Pre-value

Based on the demand of time-effectiveness,the paper proposes to divide the location process of regional emergency logistics center into two stages.The purpose of the first stage is to establish time-operation cost model and to use an enumeration method to calculate a number of optimal solution as pre-value.In the second stage,the maximum coverage model is used for the second location based on the pre-value and finally an example is shown.
