Container terminal (CT) operations are often bottlenecked by slow YC (yard crane) movements. Efficient YC scheduling to reduce the PM waiting time is therefore critical in increasing a CT’s throughput. This paper develops an efficient continuous time MILP model for YC scheduling. The model treats realistic operational constraints such as multiple inter-crane interference, fixed YC separation di...

The problem considered in this paper is to locate storage containers while a set of container storage and retrieval requests are sequenced. Two automated cranes stack and retrieve containers in a single block of a yard. The cranes cannot pass each other and must be separated by a safety distance. Storage containers are initially located at the seaside and landside input/output (I/O) points of t...

Due to mismanagement of supply chain operations, fresh produce, which deteriorates highly depending on time and operating environment (including temperature humidity), will suffer huge losses in transit, resulting substantial monetary losses. Cross-docking, as an efficient logistics operation strategy, has been widely used produce distribution the cold chain, whereas it not received adequate at...

Truck platooning has been identified as an emerging and promising operational technology with the advantages of fuel consumption savings carbon emissions reductions. We formulate truck routing optimization problem a multi-commodity network flow from transportation scheduling perspective. Based on generated through reduction aerodynamic drag by formation platooning, route each is also set to be ...
