yard crane is an important resource in container terminals. efficient utilization of the yard crane significantly improves the productivity and the profitability of the container terminal. this paper presents a mixed integer programming model for the yard crane scheduling problem with non- interference constraint that is nphard in nature. in other words, one of the most important constraints in...

This paper studies the simultaneous reshuffle and yard crane scheduling problem in the yard of container terminals, which is one of the key logistics problems affecting the operation efficiency in container terminals. Although the reshuffle scheduling problem has received many research attention due to its importance, the problem without considering yard crane is not very practical, which is be...

The logistics operation of container terminal can be exploded into several subsystems which are correlative, these subsystems connect by some handling facilities. This paper study the coordinated scheduling of three main kinds of facilities-Quay Crane(QC),Yard Truck(YT) and Yard Crane(YC), use multidisciplinary variable coupling design optimization method(MVCDO) to build YT coordinated scheduli...

In order to reduce the conflict of yard, vehicles and quay crane in the process of loading container, and upgrade safety of the ship stowage and transport economics, this paper took minimizing reshuffle times in yard and ship, minimizing the ship center of gravity, getting appropriate trim and minimizing the total moving distance of quay crane as optimization objectives to guarantee the balance...

In this paper, we studied a crane scheduling problem, i.e., the scheduling of RMCs to minimize the total weighted remaining work for the blocks in a terminal storage yard. The approach is a mix of planning method from AI and optimization methods based on MIP formulation. We implemented a DSS to incorporate both AI techniques and OR models. The experiments in simulation environment showed promis...

In automated container terminals, containers are transported between ships and storage yard by differen types of vehicles, for example, guided vehicle (AGV, yard crane (YC) and quay crane (QC). To improve the productivity of the automated container terminals, it is important to harmoniously synchronize operations of different types of container handling equipment. This paper examines the schedu...

Container terminal (CT) operations are often bottlenecked by slow YC (yard crane) movements. PM (prime mover) queues in front of the YCs are common. Hence, efficient YC scheduling to reduce the PM waiting time is critical in increasing a CT’s throughput. We develop an efficient model for YC scheduling by taking into account realistic operational constraints such as inter-crane interference, fix...

The efficiency of container handling has got great improvement with the usage of the 40ft quay crane and the twin 40 ft yard crane. Reasonable bay planning strategies is necessary to reach the high handing efficiency by the twin 40 ft yard crane. This paper studies both bay planning and row planning for yard bay allocation. The models of bay planning and row planning are created, and the discre...
