ABSTRACT
Today's proliferation of terminal types with their various features, speeds, line disciplines, and idiosyncrasies is harassing the computer system implementer who would like to serve a variety of terminals. In addition to the ability to interface to a particular terminal type, it is necessary to identify that terminal among those able to use the same hardware interface.
The advantages of more complete identification of terminal speed and type are developed. The properties of terminals are classified from the standpoint of their necessitating or facilitating such identification. Historical methods of determining the type of terminal approaching a system are discussed. A recognition character algorithm for simultaneously determining the terminal speed and type is described. Some quasi-standard terminal features are proposed that would permit the general application of such algorithms.

Scheduling of Different Automated Yard Crane Systems at Container Terminals
In this work, different variants of a branch-and-bound procedure for yard crane scheduling at seaport container terminals and their effect on the terminal's performance are studied. In particular, this work investigates the level of detail needed to ...
Modelling and simulation of high capacity waterside container handling systems at deep-sea terminals
SpringSim '08: Proceedings of the 2008 Spring simulation multiconferenceCurrent handling systems at deep-sea container terminals run into their physical limits and new methods of handling containers are needed to deal with the ever-growing container shipping volumes. We present a domain specific simulation model of high ...
A decision support system for managing combinatorial problems in container terminals
A container terminal is a facility where cargo containers are transshipped between different transport vehicles. We focus our attention on the transshipment between vessels and land vehicles, in which case the terminal is described as a maritime ...
