A time satisfaction function is introduced to build the transshipment model for emergency materials, combining the traditional point to point transportation mode and hub-and-spoke distribution mode. The total time satisfaction is defined though considering the quantity of materials as the weight of time satisfaction. The model considers quantity and arrived time of emergency materials, and has the real significance to the reasonable transportation of emergency materials, and improves the total time satisfaction. A simulated annealing algorithm imbedding with linear programming algorithm is proposed to solve the problem based on the characteristics of the model. Numerical examples are presented to demonstrate the efficiency of the model and algorithm.
