Car-carrier loading optimization can improve the transportation capacity and control the transportation cost of the logistics company.This paper proposed an integer linear programming model for the car-carrier loading problems.The optimal loading strategy of each Car-carrier can be obtained by solving this model.To solve this model,two easy sub-problems,namely,associated problem and transportation problem are split.By solving these two sub-problems,the optimal solution of the original problem can be quickly obtained.At last,numerical experiments are given to demonstrate the solving strategy.It shows that the method can quickly get the optimal loading scheme.
