Distributions to include:
-
PERT (Program Evaluation and Review Technique) Distribution
- Useful when you have estimates for minimum, most likely, and maximum values, with a tendency to weight the most likely value more heavily.
-
Triangular Distribution
- Ideal when you have estimates for minimum, most likely, and maximum values, but less certainty about the weight of the most likely value compared to PERT.
-
Normal (Gaussian) Distribution
- Appropriate for natural phenomena and when you expect values to be symmetrically distributed around a mean.
-
Log-Normal Distribution
- Suitable for modeling quantities that are always positive and have a skewed distribution, such as project durations or costs.
-
Uniform Distribution
- Used when all values between a minimum and maximum are equally likely, often in the absence of more specific information.
-
Beta Distribution
- Flexible for modeling various shapes of uncertainty, especially useful when historical data is available to fit the distribution.
-
Gamma Distribution
- Often used for modeling waiting times or project durations, especially when the distribution is skewed to the right.
-
Weibull Distribution
- Commonly used in reliability analysis and for modeling time-to-failure in projects or systems.
-
Exponential Distribution
- Useful for modeling the time between independent events, such as time between failures in a system.
-
Discrete Uniform Distribution
- Applicable when dealing with a finite number of equally likely outcomes, such as selecting from a set of discrete options.
