Lexicographically Prioritized Multi-criteria Decisions Using Scoring Function
Ronald R. Yager
We consider multi-criteria decision
problems where there is a
lexicographically induced prioritization
relationship over the criteria. We
suggest that the prioritization between
criteria can be modeled by making the
weights associated with a criteria
dependent upon the satisfaction of the
higher priority criteria. We implement
this using a prioritized scoring
operator. We show how the lack of
satisfaction to higher order criteria
block the possibility of compensation
by lower priority criteria. We show that
in the special case where the
prioritization relationship among the
criteria satisfies a linear ordering we
can use a prioritized averaging
operator.
