Date of Defense 1997-04-29 Availability unrestricted AbstractUse of the World Wide Web (WWW) for transfer of information and ideas is
increasingly popular. Java, a programming language for the WWW, provides a
simple method of distributing platform-independent, executable programs over
the WWW. Such programs allow the expansion of WWW-based computational
and analytical tools that support and enhance the existing WWW environment.
However, a WWW-based, generalized simulation package is not yet available.
Current literature motivates development of a general, WWW-based simulation
package with maximum user interactivity and cross-platform capabilities.
Advantages of such a package are discussed and explored in three potential
applications. Main advantages are wide availability, controlled access, efficient
maintenance, and increased integration. Disadvantages, such as variable download
times, are also discussed. Netsim, a general, WWW-based simulation package
written entirely in Java, is developed and demonstrated. Netsim provides
complete model creation and modification capabilities along with graphical
animation and data output. Netsim uses the event graph paradigm and
object-oriented programming. Java, event graphs and object-oriented
programming are discussed briefly. The Java random number generator is
verified for uniformity and independence. Netsim is compared to SIGMA, a
non-Internet simulation package, using a standard M/M/1 queueing model.
Comparison issues and results are discussed. Additionally, tested through
hand-tracing for coding validity, Netsim performs as theory prescribes. Netsim
documentation and user's manual are included. Netsim allows expandability for
complex modeling and integration with other Java-based programs, such as
graphing and analysis packages. Current Netsim limitations and potential
customization and expansion issues are explored. Future work in WWW-based
simulation is suggested
