Abstract
Methods for incorporating imprecision in
engineering design decision-making are briefly reviewed and compared.
A tutorial is presented on the Method of Imprecision (MoI),
a formal method,
based on the mathematics of fuzzy sets,
for representing and manipulating
imprecision in engineering design.
The results of a design cost estimation example,
utilizing a new informal cost specification, are presented.
The MoI
can provide formal information upon which
to base decisions during preliminary
engineering design
and can facilitate set-based concurrent design.
