Probability and Priority
 
 
Non-deterministic choice resolved by a “fair” random choice over possible results
- choice place allows probability distribution to be specified
- depends on model instance
 
 - more complex if multiple choices are in play
 - RISCSIM always resolves choices as a result of some transition terminating
 
Some situations call for arc priority
- could set extreme probability distribution (fudge), but prefer to make explicit.
