Multi criteria decision making (MCDM): management of aggregation complexity through fuzzy interactions between goals or criteria
Rudolf Felix
Since fuzzy set theory has been
suggested as a suitable conceptual
framework of decision making many
different approaches have been
developed. However, the subject of the
complexity of the aggregation process
and/or of the aggregation operations is
rather not discussed. Complex real
world applications on the other hand do
not excuse such a lack. In this paper it
is discussed in which way a decision
making approach based on interactions
between goals helps to manage aggregation
complexity. The management of
aggregation complexity is explained
and compared with the way how related
approaches deal with complexity. Two
challenging research topics are
suggested. These topics may help to
close the gap between these approaches
and the approach presented in this
paper.
