对混堆模式下的集装箱箱区指派问题进行了研究,在滚动式计划的基础上,以提高堆场空间资源的利用率为目标,建立了箱区间作业量均衡的多目标整数规划模型,并采用模拟退火算法进行求解.验证结果表明,该模型平衡了堆场箱区间的作业量,实现了集装箱堆场箱区空间资源的优化配置.
Assignment problem of container storage yard based on mixture storage is studied. In order to improve the utilization rate of storage space, a multi-objective integer programming model on basis of rolling plan is established and solved with simulated annealing algorithm. Analysis result shows that the imbalance of the operation volume among the blocks is minimized and the optimization of stor- age space allocation is achieved using this model
