About Calculation Types

RiskyProject has two types of calculations:

• Deterministic - this is the default calculation automatically performed when you modify a project schedule. As this calculation occurs automatically, you do not need to press the Calculation button. This calculation uses the Base input parameters (duration, start time, lag) without calculating the effect of risk or uncertainty.
• Probabilistic (Monte Carlo simulations) – Use this to calculate the project schedule and costs with uncertainties and risks.
  

Enabling or disabling automatic Monte Carlo simulations for small projects

1. Click the Schedule tab. In the Settings and Options group, click Options. The Options dialog box opens.
2. Click the Calculations tab.
3. From the Default Calculation for Small Projects option box, select one of the two options:
• Current Schedule Calculation only
• Probabilistic Calculation (Monte Carlo simulations)
4. Click OK. RiskyProject automatically determines which project is small based on your computer’s performance and the size of the project

Running probabilistic calculations

Click the Calculation button on the Schedule tab. You may cancel the probabilistic calculation at any time; however, if number of simulations performed is less than 20, no probabilistic results will be calculated.
