基于关键资源优先的三级装卸搬运分时协调策略

Time-dependent coordination strategies for key resource prioritized three-stage handling operations

研究基于关键资源优先的单元化"装卸、搬运、装卸"三级作业链的调度问题.在已知关键资源调度方案的条件下,将两个非关键各作业级的调度问题分别转化为最小单位流问题,并建立相应的0/1整数规划模型求解.为求解大规模问题,提出三级装卸搬运的分时协调策略.参照宁波港码头数据,设计面向集装箱码头的仿真算例,实验结果验证了所提出模型和策略的有效性.

The problem of unitized three-stage operational chain for material handling operations with key resource priority conditions is studied, including three sub-processes： loading, unloading and transport. Based on the known scheduling scheme of the key resource, the two non-critical stage scheduling problems are converted into the minimum unit flow problem respectively, and the corresponding 0/1 integer programming models are established. In order to solve the largescale problem, time-dependent clustering and coordination strategies are developed. In the background of real Ningbo port terminal, the numeric study is conducted to verify the effectiveness of the model and strategy.
