Abstract
The improvement of the process of design requires the evaluation of alternative design methods. A framework for evaluating graphically based, intuitive design methods is (1) solve a set of problems with a proven algorithm, (2) have a sample of designers solve the same set of problems, and (3) compare the results to identify the success of each designer or design method. A proto-typical experiment using the problem of corridor selection is used to illustrate the approach, with solutions obtained by twelve students being compared to solutions obtained by discrete dynamic programming for a set of three problems. An important distinction is drawn between measuring the success of the solution vs the success of the problem solving procedure. An extension to evaluate the handling of separately defined objectives is suggested, and questions concerning the stability of a solution with respect to minor changes in the algorithms identified.
