集装箱堆场基于混堆的滚动式计划堆存方法

对集装箱码头堆场进、出口箱混堆模型进行了研究．首先，对于一个计划周期内所有要堆放的进、出口箱，应用数学规划的方法决定了分配到各个箱区各个倍位中的箱的数量．然后，以此数量为约束条件，应用线性规划的方法决定了一个周期内对于每艘船的要分配到各箱区各倍位中的箱的数量．减少了集卡从堆场到码头前沿的行走距离，从而提高了堆场的操作效率．

A Lagrangian relaxation-based algorithm for the allocation of yard cranes for yard activities with different priorities

This paper proposes a mixed integer programming model for the allocation of rail mounted gantry cranes for four basic yard activities with different priorities.The model pays special attention to the typical features of this kind of gantry cranes,such as a restricted traveling range and a limited number of adjustments during loading and discharging operations.In contrast to most of the literature dealing with these four yard activities individually,this paper models them into an integrated problem,whose computational complexity is proved to be NP-hard.We are therefore motivated to develop a Lagrangian relaxation-based heuristic to solve the problem.We compare the proposed heuristic with the branch-and-bound method that uses commercial software packages.Extensive computational results show that the proposed heuristic achieves competitive solution qualities for solving the tested problems.
