Further, scheduling interruptions create ambiguity in real-time operations. Therefore, the present study focused on the container terminal’s ability to schedule and mitigate real-time prob...

In a container terminal, the quay cranes (QCs) are the main equipment involved in the core activities. According to a bottleneck principle, the productivity rate of QCs is related to both worker productivity and deployed yard trucks. Yet, in the literature, the berth and quay cranes allocation and scheduling problems were addressed separately from...

The interface between operations and finance has recently been of interest to both practitioners and academics, who recognize that coordinating decisions from both functions provides a great opportunity to improve the performance of firms. However, the link between dynamic lot-sizing and financing decisions remains largely unexplored in the literat...

In container terminals (CTs), the performance of quay cranes (QCs) is extremely impacted by their operators’ productivity, which makes the QC worker assignment a relevant element in the QC scheduling. Nevertheless, in the literature, this problem was tackled without considering the objectives of balancing operators’ workload and minimising the dist...

The efficient management of maritime logistics operations improves the performance of global supply chains. An important issue in container terminal operations is the scheduling of quay cranes (QCs), which is affected by the productivity rate of QCs. This productivity rate depends on the type of tasks to be completed by QCs on any given vessel. In...

Demand fluctuations influence the configuration of manufacturing workshops. Integration of optimal production planning via the replenishment organization, can significantly reduce the excessive ++reconfigurations number in each period and, thereafter, the global managing costs. In this paper, we discuss the joint machines Group layout design (GLD)...

Our study focuses on the question of national investment in sustainable development and its impact on the performance of the Sustainable Supply Chain Management.
