The Normal distribution has a distribution strategy similar to a bell curve in which numbers in the middle of the distribution scale are more likely to be generated at random, as shown in the following image:
The Normal distribution has three settings:
- Mean - The most common number on average that will be generated at random.
- Standard Deviation (Std Dev) - The amount of variation or dispersion of values relative to the mean. A lower standard deviation will cause the numbers to be very close to the mean. A higher standard deviation will generate numbers that are more widely dispersed from the mean.
- Stream - Determines which one of FlexSim's random number streams should be used to generate these random numbers. Typically you won't need to edit this parameter.
When you make changes to the settings, the blue bar graph will update to display the probabilities that certain numbers will be generated.
