Multiple Experts (Fault Tree)

Multiple Experts

DPL offers a means for combining the probability assessments of multiple experts into a single likelihood (probability of occurrence). To do this, each expert must provide an assessed probability distribution, and a weight must be assigned to each expert. DPL offers an input interface for the process of determining these weights and calculating the expected likelihood. The weights used by DPL are determined by the reliability of the expert and the amount of shared information among the experts.
