About Calculation in RiskyProject
RiskyProject has two types of calculations:
- Deterministic - The default calculation is 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
- Click the Schedule tab. In the Settings and Options
group, click Options. The
Options dialog box opens.
- Click the Calculations tab.
- From the Default Calculation for Small Projects option box, select one of the
two options:
- Current Schedule Calculation only
- Probabilistic Calculation (Monte Carlo simulations)
- 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 Calculate button. You may cancel the probabilistic calculation at any time; however,
if the number of simulations performed is less than 20, no probabilistic results will be calculated.
- By default RiskyProject performs convergence monitoring. Simulations can be stopped when they convergence equals mean
and standard deviation values defined in Schedule tab > Options > Calculation.
- Minimum number of simulations is 200.
- If you cancel a calculation after more than 20 simulations and generate results, use these results with caution as the number
of simulations which have been run may be too small to provide an accurate portrayal of the project’s risks and uncertainties.
- If you try to perform Monte Carlo simulations without risks and uncertainties, simulations will not proceed in the same manner
as when you define risk and uncertainties. Remember that uncertainties include a probabilistic calendar.
