Power Means in Success Likelihood
Abstract. The Successive Likelihood Index Method establishes the
degree of liability, and therefore the corresponding compensation, of the
various errors that have caused an accident. From an expert judgment,
the successive likelihood index of each error is calculated by a weighted
arithmetic mean of their opinions. In this work we have considered other
averaging functions for aggregating this information and we have studied
their behavior. In particular, we have studied in detail the case of power
means applied to the accident of the oil tanker Aegean Sea.
