Yard crane scheduling in port container terminals using genetic algorithm
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...

متن کاملDiscrete time model and algorithms for container yard crane scheduling
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...
متن کاملA Quay Crane Scheduling Model in Container Terminals
This paper discusses the problem of scheduling quay cranes, the most important equipment in port terminals. A simulation model is developed for evaluating time of quay cranes. Then a dynamic scheduling model using objective programming for quay cranes is developed based on genetic algorithm approach. Finally, numerical experiments on a specific container terminal are made for propose approach. ...
متن کاملQuay Cranes and Yard Trucks Scheduling Problem at Container Terminals
A bi-objective mathematical model is developed to simultaneously consider the quay crane and yard truck scheduling problems at container terminals. Main real-world assumptions, such as quay cranes with non-crossing constraints, quay cranes’ safety margins and precedence constraints are considered in this model. This integrated approach leads to better efficiency and productivity at container te...
