Yard Allocation for Outbound Containers Based on the Unified Neutral Theory of Biodiversity and Biogeography

摘要

Yard allocation is the key point of container terminal management. This paper solves the problem by minimizing the distance between the berth and the yard, offering multiple work ways, avoiding loading or collecting at the same time. The solution of yard allocation is similar with the model which all individual organisms have the same possibility to be killed in Unified Neutral Theory of Biodiversity and Biogeography. Based on the improvement of the neutral theory, this paper proposed a multiple group model to reduce the solution set. To guarantee the adjacent container group not to be put in the same yard and assure a consecutive and parallel loading process, a strategy which kills anyone of the species exist prey relationship is put forward. And a greedy strategy is proposed to select an island to accelerate the ecological balance among islands. All these strategies make ecological selection more instructive and faster to find an optimal solution. The experiments show that the model proposed in this paper owns a good performance.
