AutoMod
Chair: Matthew W. Rohrer
(Brooks-PRI Automation)
Simulating Reality Using AutoMod
Matthew
W. Rohrer and Ian W. McGregor (Brooks-PRI Automation)
Abstract:
Decision making in industry has become more complicated
in recent years. Customers are more demanding, competition is more fierce, and
costs for labor and raw materials continue to rise. Managers need
state-of-the-art tools to help in planning, design, and operations of their
facilities. Simulation provides a virtual factory where ideas can be tested
and performance improved. The AutoMod product suite from Brooks-PRI Automation
has been used on thousands of projects to help engineers and managers make the
best decisions possible. With the release of AutoMod 11.0 in 2002, AutoMod now
supports hierarchical model construction. This new architecture allows users
to reuse model objects in other models, decreasing the time required to build
a model. Composite models are just one of the latest advances that make
AutoMod one of the most widely used simulation software packages.

Non-Item based Tools
Chair: David
J. Parsons (Simulation Dynamics)
Non-Item based Discrete-Event Simulation
Tools
Richard A. Phelps, David J. Parsons, and Andrew J. Siprelle
(Simulation Dynamics, Inc.)
Abstract:
Discrete event simulation has traditionally been
defined by items (or entities). This modeling paradigm has served the
simulation industry well, but falls far short for many industries in which the
parts / pieces mindset simply does not accurately portray their particular
processes. For the last ten years Simulation Dynamics has been working with
industries where the item paradigm falls short as a descriptive tool. This
work has led to the development of a revolutionary set of simulation tools
built on the Extend simulation engine.

Micro Saint
Chair: Wendy
Bloechle (Micro Analysis & Design)
Micro Saint Modeling and the Human
Element
Daniel W. Schunk, Wendy K. Bloechle, and Ron Laughery
(Micro Analysis & Design, Inc.)
Abstract:
With new technologies emerging daily, one of the
largest problems companies currently face is the challenge of upgrading slow,
outdated systems. While it is common to consider things like cost efficiency
and automation in new systems, companies often overlook the human element in
their system redesign. By factoring in the human element, companies can avoid
having to make costly adjustments to their system because of unexpected human
error. Task network modeling is one approach to modeling human performance in
complex systems. Micro Saint is a modeling environment that supports task
network modeling and human performance modeling. This paper will discuss how
to model the human element using Micro Saint along with a brief case study.

PROMODEL
Chair: Charles R.
Harrell (Brigham Young University)
Simulation Modeling Using Promodel
Technology
Charles R. Harrell (Brigham Young University) and
Rochelle N. Price (PROMODEL Corporation)
Abstract:
PROMODEL’s simulation modeling products are powerful
yet easy-to-use simulation tools for modeling all types of systems and
processes. ProModel is designed to model manufacturing systems ranging from
small job shops and machining cells to large mass production, flexible
manufacturing systems, and supply chain systems. Other simulation products
available from PROMODEL Corporation include MedModel, ServiceModel, Innovate,
and ProModel PI (for process improvement). PROMODEL products are Windows based
applications with intuitive graphical interfaces and object-oriented modeling
constructs, eliminating the need for programming. They combine the flexibility
of a general-purpose simulation language with the convenience of data-driven
simulators. This paper provides an overview of ProModel and presents its
modeling, analysis, and optimization capabilities.

ExpertFit
Chair: Averill M. Law
(Averill M. Law & Associates)
How the Expertfit Distribution-Fitting Software can make
your Simulation Models more Valid
Averill M. Law and Michael G.
McComas (Averill M. Law & Associates)
Abstract:
In this paper, we discuss the critical role of
simulation input modeling in a successful simulation study. Two pitfalls in
simulation input modeling are then presented and we explain how any analyst,
regardless of their knowledge of statistics, can easily avoid these pitfalls
through the use of the ExpertFit distribution-fitting software. We use a set
of real-world data to demonstrate how the software automatically specifies and
ranks probability distributions, and then tells the analyst whether the "best"
candidate distribution is actually a good representation of the data. If no
distribution provides a good fit, then ExpertFit can define an empirical
distribution. In either case, the selected distribution is put into the proper
format for direct input to the analyst’s simulation software.

Extend
Chair: Doug Shannon
(TRW)
The Extend Simulation Environment
David
Krahl (Imagine That, Inc.)
Abstract:
The Extend simulation environment provides the tools
for all levels of modelers to efficiently create accurate and credible models.
Extend’s modern, advanced design and rich feature set reduce the amount of
time developing, validating, verifying, and analyzing simulation models. Model
builders can use Extend’s pre-built modeling components to quickly build and
analyze systems with little or no programming. Simulation tool developers can
use Extend’s builtin, compiled language, ModL, to develop new reusable
modeling components. All of this is done within a single, self-contained
software program that does not require external interfaces, compilers, or code
generators.

Credibility Assessment
Chair:
James D. Arthur (Virginia Tech)
A Collaborative Evaluation Environment for Credibility
Assessment of Modeling and Simulation Applications
Osman Balci,
Robin J. Adams, David S. Myers, and Richard E. Nance (Orca Computer, Inc.)
Abstract:
Credibility assessment of modeling and simulation
(M&S) applications is becoming increasingly more important as M&S
applications are used more and more for complex system design evaluation,
M&S-based acquisition, problem solving, military training, and critical
decision making. M&S credibility assessment is a very complex process,
involves the measurement and evaluation of hundreds of qualitative and
quantitative elements, mandates subject matter expert evaluation, and requires
the integration of disparate measurements and evaluations. Planning and
managing such measurements and evaluations require a unifying methodology and
should not be performed in an ad hoc manner. We have developed such a
methodology, which can be used for credibility assessment of any kind of
M&S application. To provide computer-aided assistance in applying our
methodology and to enable collaborative evaluations by geographically
dispersed people, we have developed a Web-based client/server software system.
This tutorial introduces our software system, which can be used at

AWESIM
Chair: Jean O'Reilly
(Frontstep, Inc.)
Introduction to AweSim
Jean O'Reilly
(Frontstep, Inc.)
Abstract:
AweSim® is a general-purpose simulation system which
takes advantage of the latest in Windows® technology to integrate programs and
provide componentware. AweSim includes the Visual SLAM® simulation language to
build network, subnetwork, discrete event, and continuous models. Network
models require no programming yet allow user-coded inserts in Visual Basic or
C. Discrete event and continuous models can be created using the
object-oriented technology of Visual Basic, C or Visual C++ and can be
combined with network models. This tutorial will demonstrate the process of
using AweSim’s componentware, describe examples of user interfaces that allow
integration with other applications, and present a sample model.
