6.3 Suspended Ceiling Design Process - Bilkent University

These definitions are consistent with the terms “design parameters”
(physical parameters) and “performance parameters” used by Clarkson
and Hamilton (2000) and “explicit attributes” (design parameters) and
implicit attributes (performance parameters) used by McMahon and Xianyi
(qtd. in Clarkson and Hamilton, 2000). The two different parameter types in
building design are illustrated through the exterior wall example shown in
Figure 5.10.

Although it is possible to reflect this classification scheme in a DSM, a
more useful application would be to include performance requirements in
