Railway station plays an important role in improving the operation efficiency of rail-sea intermodal container terminal. The cooperative scheduling of multiple gantry cranes (GCs) can reduce the production and operation cost of railway station. Most studies look into discarding the conflict schemes of GCs, which may obtain excellent scheduling …
This paper proposes a method to optimize the configuration and scheduling of dual trolley quay crane and AGV so as to reduce the cost in automated container terminal.

The problem of yard crane dispatching in container terminals is addressed in this paper. We proposed two new hybrid algorithms which combine the advantages of A* heuristic search and Recursive ...
A three-level, hierarchical system for yard crane (YC) management in container terminals and the algorithms for the bottom two levels were proposed in previous studies.
2. Container Terminal Equipment. A container terminal relies on an array of intermodal equipment to perform its operations, including straddle carriers, gantry cranes, and …
Yet most container terminals charge customers as they have since the 1960s—a flat rate per container moved. ... Providing an accurate and timely stowage plan is important to help a terminal plan its crane deployment and yard work. ... of this model, using the assumptions outlined in Exhibit 3. In a scenario in which lines follow their ...
The significant congestion during the COVID-19 epidemic has prompted terminal managers to prioritize efforts to enhance daily operational efficiency in the post-epidemic era. In direct response to these priorities, this study develops a dynamic stack-based yard space allocation model tailored to optimize daily yard space allocation in …

A terminal yard crane, also known as a container yard crane or a container handler, is a type of heavy-duty mobile crane used in port terminals, intermodal yards, and container …
The productivity of a container terminal can be measured in terms of the productivity of two types of operations. ... They also attempted to minimize the delay costs. The studies by Daganzo (1989) and Peterkofsky and Daganzo (1990) assumed one task per ship-bay, a task which needs crane operations during a specific length of time, and …

use of a single crane, dual passing RMGCs, twin (non-passing) gantry cranes, or the three-crane configuration (two non-passing and one pa ssing), respectively (see Section 2).
The major difficulties of the operation of loading, unloading and transportation at container terminals are how to schedule berths, quay cranes and trucks more effectively and efficiently. Therefore, how to optimize their configurations effectively and connect them more reasonably is a problem which should be solved eagerly. However, …
In this paper, it is assumed that a container terminal utilizes yard cranes to transfer containers from (to) trucks, as shown in Fig. 1. We try to devise decision rules to maximize the level of service for trucks. These decision rules, which are suggested for automated container terminals, can also be used for conventional terminals.
Currently, DRMGs are in use at the HHLA Container Terminal Altenwerder (CTA), Hamburg/Germany (see Stahlbock and Voß 2010 as well as Speer et al. 2011).The technical parameters for this crane system are provided by Koch as well as Speer and Fischer ().These settings are similar to those used for the comparison in Sect. 18.6. …
