I don't understand how to use statistical distribution for risk. Why do you use only uniform o triangular distribution? What does this distribution mean? How to use seed for the risk distribution?

You can specify statistical distribution for the moment of risk. It has nothing to do with probability of risk occurrence. Statistical distribution for the moment of risk specifies time when the risk would occur during the course of task (in percents).
For example, uniform distribution means with start time 0% and finish time 100% means that risk would occur anytime during the course of the task with equal probability.
Triangular distribution (start time 0%, most likely time 0%, finish time 100%) means that risk would occur most likely at the beginning of the task.
You may read more about moment of risk in our technical paper regarding event chain methodology.
