News Release

INCLINE VILLAGE, NV -- October 9, 2006 -- Frontline Systems is shipping Risk Solver Engine V7.0 for Excel -- a new approach to Monte Carlo simulation that enables Excel users to play 'what if' with uncertain values as easily as they do with ordinary numbers.  A trial version is available for download from www.solver.com.

Each time a user changes a number on the spreadsheet, Risk Solver Engine performs a simulation with thousands of trials -- often in no more time than a single spreadsheet recalculation -- and the full range of simulation results and statistics can be displayed instantly. Users programming in Excel's VBA language can fully control Risk Solver Engine and build custom applications.

"Risk Solver Engine provides the easy to use, lightning-fast Interactive Simulation in Excel that I've envisioned," said Dr. Sam Savage, president of AnalyCorp, consulting professor at Stanford University, and a noted authority on Monte Carlo simulation. "It has the potential to do for uncertainty what the spreadsheet did for numbers."

"Several innovative applications have already been created with Risk Solver Engine, that empower users to understand and deal with risk," said Daniel Fylstra, president of Frontline Systems.  "And now Risk Solver Engine works with our optimization software, to help users make decisions using simulation optimization of realistic-size models."

Proven PSI Technology Key to Speed

Risk Solver Engine uses Frontline's Polymorphic Spreadsheet Interpreter technology to achieve breakthrough simulation speeds -- up to 100 times faster than normal Excel-based Monte Carlo simulation -- thus making Interactive Simulation practical every time a user changes a number on the spreadsheet.

PSI Technology was first developed to greatly enhance the performance of the Premium Solver Platform, Frontline's leading product for optimization in Microsoft Excel. Licensed by Frontline to Denver-based Decisioneering Inc., it also powers the Extreme Speed feature of Crystal Ball, Decisioneering's leading product for Monte Carlo simulation in Microsoft Excel.

Support for Probability Management Concepts

Risk Solver Engine supports the practice of Probability Management and Coherent Modeling in large organizations, proposed by Dr. Savage. In addition to Interactive Simulation on every spreadsheet recalculation, the Engine directly supports Stochastic Libraries, both on the Excel spreadsheet and in Excel VBA. Certification Authorities such as the "Chief Probability Officer" proposed by Dr. Savage can approve such libraries for use in the Risk Solver Engine.

Simulation Optimization at Unprecedented Speed

Once they've modeled uncertainty, users want to make choices for the factors that are under their control, to achieve best results over the range of future scenarios explored by Monte Carlo simulation.  Risk Solver Engine works with Frontline's market-leading Premium Solver Platform for Excel to solve simulation optimization problems, at speeds often a hundred times faster than other Excel-based solutions.  Users can for example seek to maximize expected profits that depend on uncertain demand, sales and costs, while maintaining inventory levels within acceptable limits.

Models Created with Excel Functions or VBA Code

Risk Solver Engine is aimed at consultants, modelers and application developers.  It operates "behind the scenes" with no graphical user interface, offering over 70 new functions that can be used in Excel formulas to create Monte Carlo simulation models and access simulation results. It also provides a complete object model in Excel VBA that enables Visual Basic programmers to quickly create custom risk analysis applications. Uncertain inputs or 'random variables' can be defined either with functions such as PsiUniform() and PsiNormal() that define analytic probability distributions, or with a PsiSlurp() function that supplies a Stochastic Library Unit, Relationships Preserved (SLURP). Property functions may be used to specify correlations between random variables, shifting and truncation of distributions, and the like. And statistics functions such as PsiMean(), PsiVariance() and PsiPercentile() can be used to access simulation results -- instantly on every spreadsheet recalculation.

The easy-to-use VBA object model allows the user to define uncertain inputs and properties such as correlations, perform simulations, and access statistics and other simulation results -- at a high level with all the power of the function-based approach. The full Excel object model, including worksheets, charts, database access, custom user interface elements, and the like is also available in VBA, making it exceptionally easy to create custom applications.

Engine Empowers Application Developers

Consultants and application developers can use Risk Solver Engine to create a wide range of custom applications that may be offered to clients or distributed commercially. Dr. Savage's firm AnalyCorp has created custom applications for clients in several fields, ranging from oil exploration for a global firm to retirement planning for individuals.

Dr. Savage expects that "Interactive simulation models throughout organizations will serve as light bulbs, illuminating risk and uncertainty. But instead of electricity they will be powered by centrally certified stochastic libraries." Risk Solver Engine provides the technology for a more intuitive approach to dealing with uncertainty in millions of decisions made by businesses and individuals every day.
