DecisionTools Helps with
Geothermal Energy Project
Based in Reykjavík, Iceland, Enex provides renewable energy services, specializing in the development of geothermal power plants to generate electricity. The company is planning to build a geothermal power plant in Europe. In preparation for this, and to maximize expected financial gains, Enex conducted a study using Palisade's The DecisionTools Suite comprising decision and risk analysis software for Microsoft Excel. The DecisionTools software PrecisionTreeŽ, Palisade's decision analysis tool, and risk analysis software @RISK, its Monte Carlo simulation tool, enabled Enex to determine the optimal timescale for procuring equipment during the construction of this new geothermal power plant along with the optimal plant size.

Palisade 2009 Energy Risk Analysis Forum
May 21, 2009, Houston
Following the success of the 2008 Energy Forum held in Calgary in September, Palisade is pleased to announce the 2009 forum covering risk and decision analysis from all angles specific to the energy sector. The event includes hands-on software training and real-world case studies featuring @RISK and DecisionTools software. Whether you are in oil and gas, renewable energy, utilities, or related engineering services, this is an excellent opportunity to network with your peers and fellow @RISK users in your industry. The registration fee includes all sessions, food, a reception, and the book Decisions Involving Uncertainty: @RISK Tutorial for the Petroleum Industry by Dr. James Murtha. We are also calling for presenters to give case studies at the forum. Tell us how you use @RISK or DecisionTools software in your organization, and attend for free.

Why Use Risk Analysis? Part I
Wednesday, December 10, 2008
To many people, it may seem "obvious" that conducting a risk analysis will produce a better analysis and decision-making under uncertainty than just static forecasting. However, management are justified in asking whether the extra effort and potential that is required to do so is really worthwhile. Why and when does risk analysis produce better results?

Cpk; What is its "Capability?"
Monday, December 08, 2008
There seems to be some low level confusion about Cpk and Ppk and what they actually represent. Very basically, Cpk is short term "noiseless" process capability where Ppk is long term "noisy" process capability. Some of the confusion regarding these two metrics may be because the automotive industry had at one time used Cpk to represent long term process capability and Ppk for short term, the complete opposite of the rest of the Six Sigma community. They have since conformed to the industry's standard definitions. Another potential source of confusion is that Ppk is a much underutilized metric for what it measures. When developing a process performing at six sigma level, wouldn't we ultimately want be focused on Ppk instead of Cpk? That is another subject that hopefully will receive more attention in the future.

"Using @RISK to Simulate a Regression Derived
Transfer Function Created Using Minitab”
Presented by Anwar El-Homsi
TPS-Lean Six Sigma LLC - January 29, 2009, 1:00pm EST
This presentation will cover the methods used to generate and build a Regression Analysis equation and the tools necessary to evaluate and diagnose how effective the equation is. We'll also cover the application of Monte Carlo Simulation using @RISK software to assess the performance of the process.

Webcast: @RISK and DFSS
“DFSS-based Design Optimization using
Design of Experiments and @RISK ”
This webcast will take you through the fundamental steps of the Design and Optimize phases of a Design for Six Sigma product development effort. The steps involve modeling a physical system using a designed experiment, and using the model to achieve the required system performance using Monte Carlo simulation to estimate system sensitivity and capability.
This webcast is aimed at the practicing product development engineer, quality engineers and technical project managers.

Automating @RISK with VBA
Presented at the Palisade Risk
& Decision Analysis Conference
New York City, November 13, 2008
Dr. Chris Albright, author of the book VBA for Modelers, recently presented a number of examples of how to automate @RISK, RISKOptimizer, and StatTools in Excel using Excel's VBA and Palisade's built-in object-oriented Excel Developer Kit. These examples include production applications, scheduling applications, World Series simulation, and more. All examples include macros written by Dr. Albright, so you'll need to enable macros when you open them.

The Poisson Distribution
The Poisson distribution is a model for the number of events that occur in a given time period where the intensity of the process is constant (that is, it can equally be applied to processes over other domains e.g. spatial). The distribution can be thought of as an extension of the Binomial distribution (which has a discrete
domain). It is often used in insurance modeling and financial markets as a distribution of the number of events (e.g. earthquakes, fires, stock market crashes) that might occur in a given period.
RiskPoisson(lambda) specifies a Poisson distribution with the specified lambda value, where lamba must be greater than zero. The argument lambda is also the same as the mean of the Poisson distribution. The Poisson distribution is a discrete distribution returning only integer values greater than or equal to zero.
RiskPoisson(5) specifies a Poisson distribution with a lambda of 5.
RiskPoisson(A6) specifies a Poisson distribution with a lambda value taken from
