Welcome to the Spring
2005 Issue of the GoldSim Newsletter!
The mission of
the GoldSim Technology Group is to provide state-of-the-art
software, training and expert consulting to help you understand
complex systems and make better decisions in an uncertain
world. Our GoldSim simulation software package provides the
power, flexibility and usability necessary to efficiently
simulate and understand the future behavior of complex systems
in business, engineering and science.
The purpose of the GoldSim Newsletter is to provide information
that helps you get the most out of GoldSim. Like you, we don't
like getting lots of unnecessary email in our Inbox, so we
only send out our newsletter if we have something useful to
communicate (usually 2 to 4 times per year). This issue of
the Newsletter focuses on the release of our new version,
and also presents several other items of interest, including
an interesting application of GoldSim submitted by one of
our academic users, and news on what we are planning for our
Note that each Newsletter is archived
on our website so you can view old issues.
Since this newsletter is for you, we encourage you to send
us your comments and contributions. Send your contributions

GoldSim Version 9 Released!
At last! It's been in the works for over a year, and GoldSim
Version 9 is now available to download. We are very excited
about this new release, and think that you will find many
of the new features very useful.
All current members of the GoldSim
Subscription Program can download Version 9 now from the
GoldSim Resource Center (GRC). If you are not a current member,
but would like to test drive Version 9, request
an Evaluation version.
Click the Learn More link below to see an overview of some
of the new features. Due to the large number of changes in
this version, we have prepared a Version 9 Summary and Conversion
document to help existing users come up to speed with the
new features and convert existing models. This document can
be downloaded from the GRC prior to downloading the installation
file, and is also automatically installed along with the software
when you upgrade. After installation, it can be found in the
Windows Start menu (All Programs | GoldSim 9.0 | Release Info
| Converting v8 Models). Existing users are strongly encouraged
to read this document.
We appreciate and value your comments, so if you have any
feedback on the new version (both positive and negative),
we'd love to hear from you at firstname.lastname@example.org.
GoldSim Technology Group Wins NASA Research and Development
In January, the GoldSim Technology Group started work on
a NASA Small Business Innovation Research (SBIR) project,
with the goal of demonstrating an integrated total-system
risk and reliability analysis approach that is based on dynamic,
probabilistic simulation. Currently NASA relies primarily
on fault-tree analysis.
This work is expected to lead to enhancements in GoldSim's
ability to differentiate uncertainty from random processes,
and to show how GoldSim's new Reliability Module can be used
for risk and reliability assessments of future NASA missions.
The results of this research will be incorporated into the
new Reliability Module to be released this summer.

No More Free Internet? Modeling Pricing Mechanisms in Packet-Switched
Communication Networks Using GoldSim
So far, once you are connected to the Internet your usage
has been free. However, the capacity of the Internet isn't
infinite, and the day may come when you have to pay for your
usage. Professor Toma Turk, of the Economics Faculty
at the University of Ljubljana in Slovenia, has been using
GoldSim to simulate packet-switched communication networks
and the impacts on traffic of alternative pricing schemes.
Version 9 has just been released, but our development team
never rests. Here are some of the things that we are working
Reliability Module. The Reliability Module, which
enhances GoldSim's ability to do risk and reliability
studies of complex engineered systems, is nearing completion,
and will be released by the end of the summer.
Stochastic Optimization. The Optimization capability
introduced in Version 9 will be enhanced to allow you
to optimize uncertain systems. It's going to take some
time to run these analyses, but you will be able to address
problems such as "Adjust my pricing scheme so as
to maximize my expected profits, while having no more
than a 10% chance of going broke".
Two-Dimensional Monte Carlo. We're adding a capability
for you to embed one GoldSim model inside another. This
should be particularly useful for cases where you need
to separate the effects of uncertainty from randomness/variability.
You will be able to have an outer Monte Carlo model that
samples the uncertain parameters, and an inner model that
simulates system performance subject to random effects.
As always, we encourage our users to send their requests
and suggestions for improvements to GoldSim. If you have a
specific request, please contact us at email@example.com.
