Modus Ponens Generating Function in the Class of ^-valuations of
  Plausibility
  We discuss the problem of construction of inference procedures which can
manipulate with uncertainties measured in ordinal scales and fulfill to the
property of strict monotonicity of conclusion. The class of A-valuations of
plausibility is considered where operations based only on information about
linear ordering of plausibility values are used. In this class the modus ponens
generating function fulfiling to the property of strict monotonicity of
conclusions is introduced.
