Chapter 42. Distribution Types
The Distribution type property defines the distribution of possible time values, that is scores, of process elements.
The elements might use one of the following score distribution types on simulation:
-
Normal: the values are distributed on a bell-shaped, symmetrical curve. -
Uniform: the values have a rectangular distribution, that means every value is applied the same number of times. -
Poisson: the values are distributed on a negatively-skewed normal distribution curve.
42.1. Normal

The element values are picked based on the normal distribution type, which is bell-shaped and symmetrical.
Normal Distribution Attributes
- Processing time (mean)
-
The mean processing time that the element needs in order to be processed. The value uses the time unit defined in the
Base time unitproperty. - Standard deviation
-
The standard deviation of the processing time. The value uses the time unit defined in the
Base time unitproperty.
42.2. Uniform

The Uniform distribution or rectangular distribution returns the possible values with the same levels of probability.
Uniform Distribution Attributes
- Processing time (max)
- The maximum processing time of the element.
- Processing time (min)
- The minimum processing time of the element.
42.3. Poisson

The Poisson distribution returns the possible values similarly as normal distribution. However, the distribution is negatively skewed, not symmetrical. The mean and the variant are equal.
42.3.1. Poisson Distribution Attributes

- Processing time (mean)
-
The mean time for the element processing. The value uses the time unit defined in the
Base time unitproperty.
