An extension to the method of imprecision that allows the
decomposition or aggregation of imprecise design problems with
weighted attributes is presented. The method of imprecision uses the
preferences of the designer and customer to define fuzzy sets that
quantify the imprecision
associated with a design attribute. These fuzzy sets, weighted by
relative importance, are combined to produce an overall design
measure. This paper introduces aggregation operators that can be
hierarchically applied to combine weighted design attributes so that
the structure of the design problem is appropriately modeled.
