关键词：多式联运终端仿真，柔性作业车间调度，资源分配，网络流问题。提出了一种方法来决定哪些设备和人力必须在一系列工作班次中分配。一旦提供了这些资源，就可以找到一个可行的、接近最佳的操作顺序，以便在多式联运集装箱码头装卸一组船舶。资源分配问题的解决基于网络设计公式，该公式假设装卸过程可以建模为船舶和码头堆场之间所有班次的集装箱流网络。因此，调度问题的解决方案是通过详细描述每个容器从起点到目的地的路径来确保这些流在每个工作班次中持续存在的基础。采用离散事件仿真模型对资源分配和调度策略进行了验证，该模型的分辨率低至单个容器单元。
KEYWORDS Intermodal terminal simulation, flexible job-shop scheduling, resource allocation, network flow problem. ABSTRACT An approach to the problem of deciding which equipment and manpower must be allocated over a sequence of work shifts is presented. Once these resources are given, a feasible and near-optimal sequence of operations to load and unload a set of ships harboured in an Intermodal Container Terminal is found. The solution of the resource allocation problem is based on a network design formulation that assumes that the loading and unloading processes can be modelled as a network of container flows between the ships and the terminal yard for all the work shifts. The solution of the scheduling problem is thus fundamental to ensure that these flows are sustained in each work shift, by detailing for each container, the path to follow from its origin to its destination. A discrete- event simulation model with a resolution down to the single container unit is used to validate the resource allocation and the scheduling policies.
