In addition, it
has been shown that the weighted linear
combination operator commonly used with such
factors lies on a continuum with these operators,
where it represents the case of intermediate
ANDness and ORness, and full trade-off between
the factors considered. Furthermore, it has been
shown that a more general operator (the ordered
weighted average) can produce all of these results
along with a continuum of other operators with
varying degrees of trade-off and ANDORness.
This not only acts as a strong theoretical
framework for consideration of the aggregationoperator, but also provides a logic for the
standardisation of factors, a rationale for the
expression of decision risk, and a high degree of
flexibility in the land allocation decision process.
