Complex, confusing decision problems with multiple objectives have been made since the start of the civilisation. The history of the decision analysis is not that long, however. In 1730s Daniel Bernoulli (1738) first used the concept of utility when explaining the evaluation of a particular uncertain gable known as St Petersburg paradox....
