Since the premium prices of yard trucks and significantly daily volatility of containers serving demand, it is an uneconomic method to keep a full team of fleet to cover the entire service. Some of the transportation services are outsourced to other external companies. The strategy of outsourcing yard trucks is a decision making problem that container terminals are currently facing. Yard truck ...

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...

Distributed arrival time control (DATC) is a highly distributed feedback control algorithm for the scheduling problems in heterarchical operation systems [V.V. Prabhu, Performance of real-time distributed arrival time control in heterarchical manufacturing systems, IIE Transactions 32 (2000) 323–331]. Although DATC has presented outstanding performance for the real-time scheduling problems in d...

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...

This paper considers the effectiveness of a truck appointment system in improving the yard efficiency of the container terminal. This research uses truck appointment information to improve the import container retrieval operation and reduce container rehandles by adopting an advanced container location assignment algorithm. By reducing the container rehandles, the terminal could improve yard cr...

Seaport terminals recognise the need to change current practices in order to improve regional air quality while enhancing their terminals’ competitiveness. One area that terminals can do better at is to improve their yard crane operations and in turn reduce the trucks in-terminal delay. This study examines various container rehandling strategies by the yard cranes with the goal of improving the...

A solution to the problems of resource allocation and scheduling of loading and unloading operations in a container terminal is presented. The two problems are formulated and solved hierarchically. First, the solution of the resource allocation problem returns, over a number of work shifts, a set of quay cranes used to load and unload containers from the moored ships and the set of yard cranes ...

The scheduling problem is one of the most important operation in maritime ports. In this study we solved for a single quay crane and multiple yard trucks port Tripoli-Lebanon. previous proposed two exact methods but faced large instances CPU time. For reason, paper developed heuristic method (genetic algorithm) to obtain near optimal solution with an acceptable main objective minimize completio...

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...
