A technique to perform design calculations on imprecise
representations of parameters
has been developed and is presented.
The level of
imprecision in the description of design elements is typically high in
the preliminary phase of engineering design.
This imprecision is represented using the fuzzy calculus.
Calculations can be performed using this method,
to produce (imprecise) performance parameters
from imprecise (input) design parameters.
The Fuzzy Weighted Average technique is used to perform these
A new metric, called the gamma-level measure, is introduced to
determine the relative coupling between imprecise inputs and outputs.
The background and theory supporting this approach are presented,
along with one example.
