摘    要:为了保证铁路集装箱中心站高效地完成站内转运,利用阶梯恶化函数表示翻箱作业过程,并以此构建轨道式集装箱起重机调度优化模型。由于精确算法难以在合适的时间内获得大规模问题的最优解,在此提出自适应邻域搜索规划算法。该方法采用自适应大规模邻域搜索框架,并采用标准求解器求解产生的子问题。研究结果表明:本文方法在处理高达100个作业任务的算例时也能在较短的时间内给出较优解,可为站场转运作业过程中资源调度问题提供决策支持。

Abstract: To enable the efficient container transferring operations in railroad container terminals, a step-deteriorating function for modeling container rehandling operations encountered in the stacking yards was presented in the scheduling of gantry cranes. Since the problem is computationally intractable for realistic sizes via exact algorithms, an adaptive neighborhood search programming algorithm was developed. This method involves conducting an adaptive large neighborhood search (ALNS) and periodically solving a set of sub-problems using a standard solver. The results show that the proposed heuristic is highly effective in finding good-quality solutions to the instances with up to 100 tasks within a reasonable runtime, which provides support for the resource scheduling problems of container transferring process.
