Average Distribution
In simulations where little data is available to justify use of parametrized statistical distributions use the Average distribution. With this you only need to input your estimate of the average (mean) of the time (or other data).
An Average distribution in Simul8 is actually a Normal distribution with the standard deviation set to 25% of the mean.
Given this large standard deviation, its use is more appropriate when a large variability is desired – either in timings or label values.
