A Principled Analysis of Merging Operations in Possibilistic Logic
  Possibilistic logic offers a qualitative framework for representing pieces of
information associated with levels of uncertainty of priority. The fusion of
multiple sources information is discussed in this setting. Different classes of
merging operators are considered including conjunctive, disjunctive,
reinforcement, adaptive and averaging operators. Then we propose to analyse
these classes in terms of postulates. This is done by first extending the
postulate for merging classical bases to the case where priorites are avaialbe.
