This work describes an innovative operation-time-space network that can be easily adapted to model different logistic problems involving time and space decisions. In the recent literature, different time-space networks have been proposed to deal with specific requirements of problems arising in the logistic and transportation fields. The proposed network is able to deal with different types of capacity and time constraints that characterized the most part of logistic problems. The article explains how to construct the operation-time-space network, how to model time and capacity constraints of different types; moreover, it presents an application of this network to solve a logistic problem arising in the rail-sea exchange node, that is the scheduling of port rail shunting operations. Other applications are briefly introduced. Finally, the well-known quay crane scheduling problem is modeled, thanks to the operation-time-space network; the related flow model is tested by using a benchmark suite available in the literature.

一种创新的操作时空网络，用于解决具有容量和时间限制的不同物流问题

这项工作描述了一个创新的操作-时空网络，它可以很容易地适应对涉及时间和空间决策的不同物流问题进行建模。在最近的文献中，已经提出了不同的时空网络来处理物流和运输领域中出现的问题的特定要求。所提出的网络能够处理不同类型的容量和时间限制，这些限制是大部分物流问题的特征。文章解释了如何构建操作-时空网络，如何对不同类型的时间和容量约束进行建模；此外，它还提出了该网络在解决海铁交换节点中出现的物流问题的应用，即港口铁路调车作业的调度。其他应用程序进行了简要介绍。最后，由于操作时空网络，著名的码头起重机调度问题被建模；相关的流模型通过使用文献中可用的基准套件进行测试。
