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.
