Decision nets are useful in solving decision problems, where the interrelations between variables are represented as in a Bayes net, and the goal is to find a set of decision functions which maximize a utility objective. An example decision net is “Umbrella”.
Creating a
decision net is similar to creating a Bayes net. Once the decision
net is constructed, it may be solved,
after which you may want to do model-iteration
and what-if analysis.
