Defining Probabilistic Calendars

You can create a probabilistic calendar. Probabilistic calendars will be used only for Monte Carlo simulations. The current project schedule will use the project calendar. Probabilistic calendars are a set of base calendars with their respective probabilities.

Defining probabilistic calendars

To define probabllistic calendars:

  1. Click the Schedule tab. In the Schedule and Calendars group, click Working Time.
  2. Define base calendars that will be used for your probabilistic calendar. For example, if you would like to model that March will be 50% non-working, you need to create a base calendar entitled 'March non-working'.
  3. Click the Schedule tab. In the Settings group, click Project Settings.
  4. Enter probabilities for each base calendar. For the example above, enter 50% probability for the standard calendar and 50% probability for 'March non-working'. The sum of all probabilities must be exactly 100%.

Calculations with probabilistic calendars are performed according to the following rules:

  • If a resource calendar is used, base calendar for resources would probabilistic calendar. For example, you have a resource Crew that has a non-working exception for February 18 on the standard calendar. This exception will be applied to the standard calendar 50% of the time and to the 'March non-working' another 50% of the time.
  • If the task calendar is defined, the probabilistic calendar will be ignored and the task calendar will be used.
  • If there is no task calendar or resource calendar defined, the probabilistic calendar will be used.
