Q: Suppose an unbounded distribution (e.g., a normal distribution) is entered for the Lost
Units After Failures, Lost Units After Stops, or Lost Units After Changeovers
operands. What happens if a negative number is sampled from the distribution?
A: You cannot have “negative” loss for an event. Arena Packaging converts negative loss
quantities to zero.
