Insert a Monte Carlo simulation

What is Monte Carlo simulation?

If you want to improve your product or service by using simulated data, you can insert and run a Monte Carlo Simulation. Monte Carlo simulation uses repeated random sampling to simulate data for a given mathematical model and evaluate and optimize the outcome.

  1. Choose Insert > Monte Carlo Simulation.
  2. After you insert a Monte Carlo simulation, there are four main steps to running a simulation in Minitab Workspace.
    1. Define the model and run the simulation. Enter the variables and the response equation manually, or click Import Models from Minitab and import them from a Minitab 19 project.
    2. Review the results.
    3. Perform a parameter optimization.
    4. Perform a sensitivity analysis.

After you run a Monte Carlo simulation, Minitab Workspace displays the results, how your results compare to generally accepted values, and guidance for next steps.

What is parameter optimization?

Parameter optimization identifies optimal settings for the inputs that you can control. Minitab Workspace searches a range of values for each input to find settings that meet the defined objective and lead to better performance of the system.

What is sensitivity analysis?

Sensitivity analysis identifies inputs that have little effect on the variation of the output, or inputs that reduce the variation of the output. Minitab Workspace displays a graph that shows the effect of changing the input standard deviation on the percent of output that is out of spec.

After you analyze the results, you can change inputs or outputs, and then rerun the analysis to evaluate a number of "what if" scenarios.
