Journal of Vibration and Acoustics, Transactions of the ASME | Published : 1995


Methods for incorporating imprecision in engineering design decision-making are briefly reviewed and compared. A tutorial is presented on the Method of Imprecision (Mol), 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 Mol can provide formal information upon which to base decisions during preliminary engineering design and can facilitate set-based concurrent design. © 1995 ASME.
