Back

• Stochastic Multiattribute Utility based Decision Analysis !!
  • Using Monte Carlo methods, specified uncertainties in attribute outcomes from each decision are induced and a performance-rank probability matrix tabulated as output (Pij, probability ith decision is jth best)
  • Correlations between attributes can be incorporated into randomization process via Latin Hypercube Sampling
  • Probabilities of each decision alternative's violating specified critical linear/nonlinear constraints on sets of attributes are also computed e.g. Cij, probability ith decision causes jth catastrophic failure
  • Possible to construct LaGrangian-based loss metrics for constrained-best i.e. "best subject to not violating any constraint" and compute constrained-best probabilities and expected losses.
  • Remember....you saw it here first!!
