Autumn 2008 GoldSim Newsletter
The mission of the GoldSim Technology Group is to help you make better
decisions in an uncertain world by providing state-of-the-art software, training
and expert consulting. Our GoldSim simulation software package provides the
power, flexibility, and usability to efficiently simulate and understand the
future behavior of complex systems in business, engineering, and science.

GoldSim Version 10 Beta Available for Download
A Beta release of GoldSim Version 10 is now available from the GoldSim
Resource Center (GRC). GoldSim Version 10 has a very large number of new
features and enhancements, and all current GoldSim users are encouraged to give
it a test drive.
The Beta version installs in parallel to your current version and shares your
existing license, so you can experiment with the Beta while maintaining and
using your current GoldSim version.
You can view a document summarizing the extensive changes included in Version
into the GRC to download GoldSim Version 10 Beta
Save the Date: 2009 GoldSim User Conference
The 2009 GoldSim User Conference is moving back to our hometown,
Seattle Washington on
June 22-24, 2009.
The Conference will be held at the
Monday, June 22 will be dedicated to a GoldSim training and refresher course.
The User Conference itself will follow on June 23 and 24.
The conference and training provides a terrific opportunity for you to share
experiences with other users and the GoldSim developers, and to provide input
for the future development of GoldSim. As always, we will schedule several
social events in the evenings so you can enjoy the sights of one of the world's
most beautiful cities while networking with fellow GoldSim users.
The program for the conference will include workshops and seminars to improve
your GoldSim skills, presentation of a number of invited papers from our most
experienced and knowledgeable users on topics of general interest, a poster
session so you can see how other users are applying GoldSim, a model contest so
you can show off your GoldSim skills (and learn from others), and several
breakout sessions so users with common interests can share ideas
A detailed program and further information for reserving your spot will be
provided before the end of the year.
Featured GoldSim Application
Using GoldSim to Simulate the Impact of California's Water Management
Practices on Salmon Populations
The State of California
wrestles with a number of complex water resource issues that affect humans and
wildlife alike. As in any ecosystem, critical, and sometimes unexpected,
cause-and-effect relationships exist. It is imperative that
California's water management strategies help sustain and recover its diverse
fish populations. In order to model the impacts of
California's myriad water management strategies on the
state's salmon populations.
Cramer Fish Sciences, a Sacramento
fisheries and environmental consultancy, used GoldSim to develop a salmon life
cycle model. The model forecasted how small changes in various water projects
would affect the current and future salmon populations. The model identified the
most viable, environmentally-friendly water management strategy for the State of
California to implement. This article briefly discusses
Cramer's modeling application.
Using Importance Sampling to Model High-Consequence, Low-Probability
For risk analyses, it is frequently necessary to evaluate the
low-probability, high-consequence end of the distribution of the performance of
the system. Because the models for such systems are often complex (and hence
need significant computer time to simulate), it can be difficult to use the
conventional Monte Carlo approach to evaluate these low-probability,
high-consequence outcomes, as this may require excessive numbers of
To facilitate these type of analyses, GoldSim allows you to utilize an
importance sampling algorithm to modify the conventional Monte Carlo
approach so that the tails of distributions (which could correspond to
high-consequence, low-probability outcomes) are sampled with an enhanced
