An optimization model of the problem is formulated, which determines the transportation mode while selecting the 3PL providers and minimizes the total logistics costs subjective to the constraint of distribution time. According to the characteristic of the model of the problem, a Shuffled Frog Leaping Algorithm(SFLA) is developed to solve it. Finally, several simulation experiments are executed to verify the reasonability of the model and test the effectiveness of SFLA. The results of the experiments indicate that the proposed model can describe the problem reasonably and SFLA can solve the problem effectively. %U http://cea.ceaj.org/EN/10.3778/j.issn.1002-8331.1803-0463
