Advantages and Disadvantages of BBN

Advantages

  • Intuitive, graphical, and efficient
  • Accounts for sources of uncertainty
  • Allows for information updating
  • Models multiple interdependencies
  • Models distributed & interacting systems
  • Identifies critical components & cut sets
  • Includes utility and decision nodes

    Disadvantages

    • Not ideally suited for computing small probabilities
    • Practical limitations on the type of distributions and the form of statistical dependence
    • Computationally demanding for systems with a large number of random variables
    • Exponential growth of computational effort with increased number of states
