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 constructs a berth-quay crane capacity planning model with the lowest average daily cost in container terminal, and analyzes influence of number berths quay cranes on terminal operation. The object is to optimize maximize benefits terminal. A steady state probability transfer based Markov chain for constructed by historical time series queuing process. current minimum operation princ...

Decision support systems and automated planning have become essential for the effective management of seaport container terminals. Due to ever-increasing levels maritime traffic freight transportation, terminals are expected facilitate their intra-yard operations while respecting tighter vessel schedules. Employed models must therefore be capable providing berth allocation decisions which not o...

Efficient management of port resources plays a crucial role in reducing vessel stay times and avoiding the payment demurrage charges. In this paper, we focus on integrated Laycan Berth Allocation Quay Crane Assignment Problem, which considers three main decision problems an way: dynamic continuous Problem time-invariant Problem. second part, problem is extended to Specific Assignment, includes ...

Workers in ports work with and close proximity of heavy machinery. Quay cranes used for moving containers between ships the dockside yard are one most accident-prone equipment types. For picking up containers, these equipped spreaders, i.e. lifting devices which lowered down on top lock to them mechanically. We concerned here monitoring a quay crane spreader so as make sure that safe clearance ...

Maritime transportation plays a critical role in global trade as it accounts for over 80% of all merchandise movement. Given the growing volume maritime freight, is vital to have an efficient system handling ships and cargos at ports. The current first-come-first-serve method insufficient maintaining operational efficiency, especially under complicated conditions such parallel scheduling with d...
