Simulation Master

See your risks more clearly

Simulation Master is an Excel® add-in for Monte Carlo simulation and much more. Take your spreadsheet models to another level by replacing single point estimates with a more in-depth analysis. See outcome probabilities and the spectrum of potential outcomes in ways that aren’t possible with traditional models.

The applications of Simulation Master are endless. You'll find the combination of features, world-class support, and price is an exceptional value.

If you're not sure how to build a model, we'll build it together at no additional cost.

Your Problems Solved | Your Performance Improved

Risk analysis and Monte Carlo simulation are often intertwined.  Of course simulation is great for risk analysis, but there are many problems beyond risk analysis that Simulation Master can solve.

Find the probability that your project has a positive net present value.

Replace single point estimates with a range of possible outcomes.  If you generate an NPV based on single point estimates, what is the probability that NPV is positive?

You’re putting together a cost estimate where some costs are variable.

Replace them with random variables and simulate the total cost.  You can see the all the possible total costs and their probabilities.

How to balance a portfolio given a risk tolerance?  You don’t want to lose money more than 5% of the time.  How should you allocate funds for the 10 assets you’ve chosen to invest?

Use simulation with optimization to find the proper asset weights for the portfolio.

What’s the value at risk and the expected shortfall of my portfolio?

Simulation Master has tools to calculate these measures instantly.

What’s the probability that the project finishes on time?

Replace best guess task time estimates with three point estimates.  Run a simulation to find the range of project completion times and their probabilities.  Understand the risks to your schedule and the tasks that are the biggest source of risk.

You’ve got an integral that can’t be solved analytically.

Use Monte Carlo simulation to estimate it.  Simulation Master has an integration tool that estimates integrals up to four dimensions.

Complicated mechanical assemblies where tolerance stack-up is a problem.

Given the variation in the manufacturing processes of each part, you can estimate the assembly rejection rate.

Probabilistic design.

The dimensions, strengths, loadings are all random variables.  Simulate each random variable and estimate the failure rate.

You’ve got random variables in your model, but want to know the optimum values of variables you can control.

Simulation Master’s optimizer can find the optimum values of your decision variables.

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 it 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 Versions

There are two versions 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 version has all the features of the standard edition plus more advanced features for the power user.
