Abstract: For the overbooking problem of ocean shipping container position with stochastic capacity，an overbooking model with the expected total cost as the optimization objective is constructed by considering the empty container transportation and the impact of overbooking levels for credit standing，where the uncertain capacity of container position is set to be discrete stochastic variable.The solving method for the optimal solution of the overbooking model is given based on chaos optimization algorithm.The existence and uniqueness of the optimal solution are proved when the ratio of the container arriving is taken to be random variable subjecting to uniform distribution.Finally，the result from numerical example illustrates the effectiveness of the method proposed.
