EGR 100 Chapter 8: Conceptual Design
Document Summary
Once the design space is generated there is need to evaluating the designs and indentifying one design that satisfy the client"s specification. Design alternatives that don"t meet constraints must be immediately rejected as infeasible. Three main methods of evaluations are discussed here, they are: The matrix shows both constraints (upper rows) and objectives (lower row). The entities are evaluated in numerical appropriately and a design is selected according to the client"s specification. It is a simpler, quantitative version of the numerical evaluation matrix. The objectives are simply ranked high (three checks), medium (two checks) or low (one check) on the basis of priority. Similarly, metric results are assigned as 1 if they are awarded more than some arbitrary, but high value, and as 0 if their award is less than the targeted value. This method is user friendly, however this method loses considerable information that may be useful in differentiating between relatively close alternatives.
