The service level and efficiency requirements of modern coal cargo terminals for overall port scheduling are constantly improving.The unloading solution of the coal cargo yard in Huanghua Port has problems of long manual decision-making time，operation conflict，and long train time in port.Therefore，this paper studies the automatic decision-making method for unloading in the coal cargo yard in Huanghua Port.Considering the characteristics of equipment flow uniqueness and train splitting，the paper proposes an innovative solution with a neighborhood searching strategy to minimize the train waiting time，maximize the matching score，and improve the searching efficiency of the algorithm.The results show that the innovative solution can make decisions within one minute and performs better than manual decision-making.
