Reliablility

Certainty:
  • Assume complete given knowledge
  • All potential outcomes known
  • Best outcome determined easily
  • Can be very complex
Uncertainty:
  • Incomplete given information
  • Several ‘acceptable’ outcomes for each decision
  • Probability of occurrence of each outcome unknown
  • Assess risk and willingness to take it
  • Pessimistic/optimistic approaches
