Simulation Master

See your risks more clearly

Simulation Master is a Monte Carlo simulation tool and so much more...

Imagine a tool where you can track, rank, and analyze risks in-depth.  Simulation Master is a an Excel add-in that is a comprehensive risk management and risk analysis solution.

Maintain a risk register, qualitatively analyze risks and quantitatively analyze risks with Monte Carlo simulation.

Track and analyze your risks in one place.

Easily rank risks qualitatively so you can find the risks that are most important.

Communicate risks to stakeholders and risk owners quickly and efficiently.  Simulation Master has a wide array of reports and charts so you can focus on risk instead of manipulating a spreadsheet.

Drill down into critical risks using Monte Carlo simulation.  Avoid the flaw of single point estimates so you can get a more realistic view of risk.

You don't need to be an Excel expert!

100% Excel

Simulation Master runs 100% inside Excel in an environment with which you are already comfortable.  All reports and charts are Excel native objects allowing you to edit them for communication with colleagues.

Ease of Use

All simulation functions can be entered directly in the worksheet.  If you’re not sure how to enter them, Simulation Master has assistance tools to enter random variables, time series, decision variables, and copulas for you.

How Simulation Works

Walk through the process of a simulation.

Product Interoperability

If you have a decision tree created with DTace, instead of discrete outcomes, you can simulate chance node outcomes with Simulation Master.

If you have a machine learning model created with Vaimal, you can simulate the model with Simulation Master.  This is a powerful combination that allows data models to be used with analytic simulation models.

Data Transparency

All simulation data can be saved to a worksheet.

Compare Editions

There are two editions of Simulation Master to meet your needs, a standard edition and a premium edition.  The standard edition is a full Monte Carlo simulation add-in package, and is perfect for the light user.  The premium edition has all the features of the standard edition plus more advanced features for the power user.  Both editions contain full risk register and qualitative capabilities.


"A comprehensive, cost-effective solution that will bring your risk analysis and management to new levels."
