Defi nition
A distribution definition describes how values are distributed over a defined
value range.
It is a stereotype ?«distributedProperty?» of the UML element property.
A distribution defi nition describes how values could possibly be distributed.
Specifi c distribution defi nitions have to be defi ned as specialized stereotypes.
SysML defi nes the interval distribution and the normal distribution as basic examples
( Figure 4.34 ).
The notation corresponds to the notation for standard stereotypes. You can see
an example for the interval distribution for the value operatingTemperature in
Figure 4.
