Abstract In order to solve the problem of allocation of two resources-berth and quay crane in container terminals, this paper developed an integrating optimization method to make decisions of the two aspects simultaneously with the objective function of minimizing the total stay time of vessels, and an integrating optimization mathematical model was built. The paper developed a two-level iterative algorithm by separating decision objections. On the first level, the genetic algorithm was presented to optimize the priority list of vessels served and the QC numbers allocated. And on the second level of the algorithm, the paper developed an integrating scheduling plan of berth allocation and QC assignment. Numeral experiments were conducted to prove the validity and superiority of the algorithm proposed.
