Abstract
This research develops an object-oriented

approach to model airport ground network

traffic operations. A generic modeling library

is developed as a tool kit to model the basic

traffic operations in the airfield using an

object-oriented approach. The proposed

generic modeling library for airfield

operations is a collection of predefined

abstract components implemented in the Java

object-oriented programming language.

Classes are defined and used as the basic

components in a variety of airfield operation

modeling, simulations, and optimizations. The

generic airport modeling framework consists

of a set the components that are necessary for

modeling the basic activities of airfield traffic

operations. By using the multi-threading

techniques, components are integrated into the

proposed modeling framework. Unlike

traditional sequential simulation model, this

framework organizes simulation activities into

four major groups which are: flight schedule,

aircraft movement, time, and animation.

Instead of using built-in control logic, the

framework adapts an open system policy

which gives the flexibility to the end users to

incorporate the user-preferred control logic

into the end models. Another purpose in this

research is to provide a future mechanism to

study airfield ground traffic automated

control systems with Just-In-Time forecasting

and model system performance in a real-time

ATC environment. The proposed generic

library could be implemented into a

Internet/intranet ready application which can

query real time information and provide real

time advice to pilots and air traffic

controllers. This study is one of a few current

research projects that are of using multiple

threading technique to study traffic operation

problems. The proposed generic library is

originally implemented with C++ and, in the

final stage, with Java, a truly cross-platform

object-oriented language. Application written

in Java can run on most of the mainstream

computer operating systems without

modifications. Although the proposed library

is for airfield traffic control system, it could

also be extended into air traffic control

system as well as advanced transportation

system.
